Ama-Storz couplings angesinye sezinhlelo zokuxhuma ezaziwa kakhulu emikhakheni yezokucisha umlilo yanamuhla, ahlukaniswa ngama-lugs awo ayi-bayonet alinganayo kanye ne-quarter-turn locking mechanism evumela amaqembu ezicishamlilo ukuthi axhume amahose ngemizuzwana ngaphandle kwemicu. Ngokungafani nama-threaded fittings endabuko adinga ukuqondanisa okunembile kanye nokuphendula okudinayo, idizayini ye-Storz isebenzisa izingxenye ezimbili ezifanayo ezihlangana ndawonye futhi zikhiyeke ngokuphenduka okulula, okunciphisa kakhulu isikhathi esidingekayo ukuze kumiswe ukutholakala kwamanzi ngesikhathi sezimo eziphuthumayo. Lawa ma-couplings asetshenziswa kuyo yonke imishini yezicishamlilo, ukuxhunywa kwama-hydrant, izinhlelo zama-standpipe, namaphakethe amahose ezakhiweni eziphakeme, lapho umzuzwana ngamunye wesikhathi sokusabela ungasho umehluko phakathi kokuqukatha umlilo nokulahlekelwa isakhiwo. Ukusebenza kwe-Storz coupling ngakho-ke akukhona nje udaba lokulula kodwa kuyisici esiqondile ekuphepheni kokusebenza, ukwethembeka kokulethwa kwamanzi, kanye nokuqina kwesakhiwo somugqa wonke wehose ngaphansi kwengcindezi enkulu ye-hydraulic. Iminyango yezicishamlilo eNyakatho Melika, eYurophu, nase-Asia isebenzisa ama-Storz connections ngoba anikeza ukuhlangana okuphindaphindekayo nokuthembekile noma ngabe amagilavu agqokekile, ukungaboni kahle, nokugeleza kwamanzi okunengcindezi ephezulu kuyinkimbinkimbi umsebenzi. Ngenxa yokuthi i-coupling kumele imelane nengcindezi yangaphakathi enkulu, imithelela ephindaphindwayo emgwaqweni nasezindlini zezimoto, izinga lokushisa elishintshashintshayo, kanye nokuchayeka kumakhemikhali anamandla avela ku-firefighting foam, ukukhethwa kwe-alloy eyisisekelo nendlela yokukhiqiza kuyisinqumo esibalulekile sobunjiniyela hhayi nje ukucabangela izindleko.

Emkhakheni wezokucima umlilo, izinhlobo ezimbili zezinto ezenziwe nge-aluminium ezihamba phambili emakethe: i-ZL104 cast aluminium, evame ukusetshenziswa kuma-coupling enziwe nge-die-cast noma nge-sand-cast, kanye ne-6061-T6 forged aluminium, emele izinga eliphezulu lezinto ezenziwe ngomshini noma ngokushaywa. Into ngayinye iletha iphrofayili ehlukile yamandla okudonsa (tensile strength), ukunwebeka (elongation), ukuziphatha kokugqwala (corrosion behavior), nokusebenza kokukhathala (fatigue performance) okuthinta ngqo ukuthi i-coupling izosebenza isikhathi esingakanani ensimini kanye nokuthi ingakwazi ukumelana nokucindezela okungakanani ngokuphephile. Izinduna zezicishamlilo kanye nezikhulu zokuthenga ziya zibuza imibuzo eqondile mayelana nokulindeleka kwesikhathi sokusebenza, amazinga okucindezela okuqhuma (burst pressure ratings), nokuthobela izindinganiso ezifana ne-NFPA 1963, ngoba izindleko zokwehluleka kwe-hose coupling zidlula kakhulu intengo yento ngokwayo. Ukwehluleka ekuxhumaneni ne-hydrant ngesikhathi somlilo osebenzayo kungaphazamisa ukunikezwa kwamanzi emigqeni eminingi yokuhlasela, kubeke izicishamlilo engozini, futhi kudinga ukushintshwa okubizayo kwezingxenye ze-hose ezilimele. Lesi sihloko sinikeza ukuqhathanisa okuningiliziwe kobunjiniyela phakathi kwe-ZL104 cast aluminium ne-6061-T6 forged aluminium Storz couplings, kusetshenziswa izimiso ze-metallurgy, umehluko ezinqubweni zokukhiqiza, idatha yesikhathi sokusebenza, kanye nemiphumela ebhaliwe yokuhlolwa kwengcindezi, ukusiza abathengi ukuthi benze isinqumo esinokwaziswa mayelana ne-inventory yabo yama-hose coupling ezicishamlilo.

ZL104 iyingxubevange ye-aluminium yaseShayina evamile, ebizwa ngokusemthethweni ngaphansi kwesigaba se-GB/T 1173, equkethe cishe amaphesenti angu-8.0 kuya ku-10.5 we-silicon, amaphesenti angu-0.2 kuya ku-0.5 we-magnesium, kanye namanani amancane e-manganese, iron, kanye ne-copper njengezinto ezisele. Ukuba khona kwe-silicon ephezulu kunikeza i-ZL104 ukugeleza okuhle kakhulu esimweni sokuncibilika, okwenza ifaneleke ngokukhethekile ekwenzeni ngokucindezela nokwenzeni ngesihlabathi kwezimo eziyinkimbinkimbi ezifana nama-lugs, ama-flutes, kanye nemisele yokukhiya atholakala kuma-Storz couplings. Ngemva kokuthelwa, ingxubevange ivamise ukuthi yenzelwe ukwelashwa ngokushisa kwe-T6 okubandakanya ukwelashwa ngesisombululo okulandelwa ukuguga okwenziwayo, okukhiqiza amandla okudonsa asukela ku-230 kuya ku-275 megapascals namanani okunwebeka acishe abe ngamaphesenti angu-2 kuya ku-4. Isakhiwo esincane se-ZL104 etheliwe siqukethe i-aluminium matrix eqiniswa izinhlayiya ze-eutectic silicon, futhi lezi zinhlayiya zingaba zimbi futhi zibe buthaka uma izinga lokupholisa lingalawulwa ngokuqinile, okudala izindawo ezingaba umsuka wokuqala kwemifantu emincane. Esimweni sayo sokuthelwa nje, ingxubevange inikeza amandla afanelekile emithwalweni engashintshi kodwa ibonisa ukunwebeka okuphansi uma kuqhathaniswa, okusho ukuthi umthelela onzima ungabangela ukuthi ingxenye iqhekeke kunokuba iguquke ngokomzimba. Ukumelana nokugqwala kumaphakathi, futhi ulwazi lwasemkhakheni lungabonisa ukugqwala okungaphezulu ezindaweni ezinomswakama noma ezinosawoti ngaphandle kokuthi kusetshenziswe ungqimba lokuvikela lwe-anodizing noma lokumboza.

6061-T6 i-aluminium alloy ehlinzekwe ngokuqina (precipitation-hardened) eyenziwe ngendlela yokusebenza, elawulwa yizinga lamazwe ngamazwe elihlanganisa i-alloy 6061, equkethe cishe amaphesenti angu-0.8 kuya ku-1.2 we-magnesium, amaphesenti angu-0.4 kuya ku-0.8 we-silicon, kanye nokwengezwa okuncane kwe-copper, i-chromium, ne-iron. I-T6 temper itholakala ngokwelashwa ngokushisa kwe-solution cishe ku-525 degrees Celsius, ukupholisa ngokushesha (rapid quenching), nokuguga okwenziwayo (artificial aging) cishe ku-175 degrees Celsius, okukhipha izinhlayiya ezincane ze-magnesium-silicide ezikhulisa amandla kakhulu. Esimweni se-T6, i-6061 ibonisa amandla okudonsa (ultimate tensile strength) acishe abe ngu-290 kuya ku-310 megapascals, nokunwebeka (elongation) ngokuvamile phakathi kuka-10 no-17 amaphesenti, okwenza ibe nokuguquguquka (ductile) nokuqina kakhulu kune-ZL104 eyenziwe ngokuthululwa (cast). Indlela yokukhiqiza ngokushaya (wrought manufacturing) ihlukanisa isakhiwo esikhulu se-dendritic esihambisana nokuthululwa, ikhiqize isakhiwo esihle se-grain esilinganayo (equiaxed grain structure) esisabalalisa ingcindezi ngokufanayo kuyo yonke ingxenye yento futhi simelana nokusakazeka kwemifantu (cracks). I-Forged 6061-T6 nayo ibonisa ukumelana nokugqwala okungcono kakhulu, ikakhulukazi ezindaweni ezisogwini nezemboni, futhi iphendula kahle kakhulu ku-hard-coat anodizing engakwazi ukukhuphula ubulukhuni bengaphezulu kakhulu kunensimbi eyisisekelo. Ngenxa yokuthi izimboni ze-aerospace nezimoto bezisebenzisa i-6061-T6 amashumi eminyaka, ulwazi lwezakhiwo zayo lubhalwe ngokujulile, futhi yamukelwa emhlabeni wonke njengento enokwethenjelwa kakhulu ezingxenyeni ezingaphansi kwengcindezi ejikelezayo (cyclical pressure) nokushaqeka kwemishini (mechanical shock).

Ukuqhathanisa okuqondile kakhulu phakathi kwalezi zinsimbi ezimbili kuveza ukuthi i-6061-T6 forged aluminium inamandla aphakeme kakhulu okudonsa (ultimate tensile strength) acishe abe ngu-15 kuya ku-30 amaphesenti ngaphezu kwe-heat-treated ZL104, kanye nokunwebeka (elongation) okuphindwe kathathu kuya kahlanu, okuhumushela ekumelaneni okungcono kakhulu nokulimala okubangelwa umthelela nokuqhekeka ngenxa yokukhathala (fatigue cracking). Ukuziphatha kokugqwala nakho kuhluke ngokuphawulekayo, ngoba i-wrought 6061-T6 yakha ungqimba lwe-oxide oluqhubekayo nolunamathelayo kakhulu kune-cast ZL104, okungenzeka ibe ne-micro-porosity evumela umswakama ukuba ungene ebusweni futhi usheshise ukugqwala okugxile endaweni ethile. Mayelana nesisindo, zombili lezi zinsimbi zinobuningi obucishe bufane obungaba ngu-2.7 amagremu nge-cubic centimeter ngayinye, ngakho-ke ukukhetha impahla akushintshi ngokubonakalayo isisindo sonke se-Storz coupling, kodwa ubuhle bamandla be-6061-T6 buvumela ukwakheka kwezingxenye ezincanyana ngaphandle kokudela umthwalo lapho umkhiqizi ekhetha ukuthuthukisa i-geometry. Ukunwebeka okuphezulu kwe-6061-T6 kusho ukuthi i-coupling ewela enkomeni yomlilo iwela kakhonkolo kungenzeka igobe noma ibhoboze kunokuba iqhephuke, igcine okungenani ukusebenza ngokwengxenye futhi yehlise ubungozi bamaqephu abukhali angalimaza izandla ezigqokile. Ngakolunye uhlangothi, ama-ZL104 cast couplings avame ukukhethwa ezimweni ezibheka isabelomali lapho indawo yokusebenza ingenabungozi futhi i-coupling ngeke ithinteke kanzima kaningi, ngoba izindleko eziphansi zempahla nokukhiqiza zikhiqiza umkhiqizo ofinyeleleka kalula ngentengo. Kubalulekile futhi ukuqaphela ukuthi ukwelashwa kwendawo engaphezulu kunganciphisa umehluko phakathi kwalezi zinto ezimbili, ngoba i-anodizing yekhwalithi ephezulu ku-cast ZL104 coupling ingathuthukisa kakhulu kokubili ukusebenza kokugqwala nokumelana nokugqokwa emshinini wokukhiya.

Ukukhipha (casting) kukhiqiza i-Storz coupling ngokuthela i-ZL104 encibilikile emgqonyeni wensimbi noma isikhunta sesihlabathi, lapho insimbi ewuketshezi igcwalisa umgodi bese iqina ibe isimo sangaphandle sokugcina, kunikeza inzuzo yokukhiqiza okucishe kufane nesimo sokugcina (near-net-shape) okunciphisa ukumosheka kokucwenga. Nokho, ukuqina kuyinqubo yokushisa okuhlukahlukene, ukuncipha okungafani, nokukhishwa kwegesi, konke lokhu kungangenisa izimbotshana (porosity), imigodi yokushwabana (shrinkage cavities), ukufakwa kwe-oxide (oxide inclusions), nokushisa okubandayo (cold shuts) okusebenza njengezindawo ezigcina ingcindezi ngaphakathi kwengxenye eqediwe. Izinga lokuphola alivamisile ukufana endaweni yonke emshinini oyinkimbinkimbi, ngakho isakhiwo sokusanhlamvu (grain structure) sokukhipha sivame ukuba lukhuni futhi siqondiswe ngendlela ethile, kube nezindawo ezibuthakathaka lapho imingcele yokuqina ihlangana khona futhi ibambe uketshezi olusele oluhle lube yizimbotshana. Lezi zinkinga zangaphakathi kunzima ukuzithola ekuhlolweni okuvamile ngamehlo futhi zingabonakala kuphela ngemva kwezinkulungwane zemijikelezo yengcindezi, lapho imbobo encane ikhula ibe umfantu wokukhathala (fatigue crack) ogcina usakazekele phezulu. Umkhuba omuhle wokukhipha, okuhlanganisa ukulawula izinga lokushisa lesikhunta, ukwakheka kokungenisa (gating design), nokwelashwa ngokushisa ngemva kokukhipha (post-casting heat treatment), kunganciphisa ubuningi bezinkinga, kodwa izindlela zokuhlola ngezibalo ezifana ne-X-ray radiography nokuhlola ngopende ongena (dye penetrant testing) ziyadingeka ukuze kutholakale ikhwalithi engaguquki. I-Porosity iyingozi kakhulu ku-coupling yokucisha umlilo ngoba amanzi angaphansi kwengcindezi angangena embotsheni exhumene nomphezulu futhi aqhubekisele phambili ukugqwala noma ukukhula komfantu ngemijikelezo yokubanda nokuncibilika ngesikhathi sasebusika. Ngenxa yalokho, ukuthembeka kwe-coupling ekhiqiziwe kuncike kakhulu emandleni nasekuqineni kokulawulwa kwekhwalithi komkhiqizi othile kunokuba kuncike kuphela ekwakhekeni kwe-alloy.

Ngokuphambene, ukukhandwa kuqala nge-billet noma i-preform ye-aluminium engu-6061 efudunyezwa ibe isimo esiphephile bese icindezelwa ngaphansi kwengcindezi ephezulu kakhulu kusetshenziswa ama-dies abumba ingxenye kuyilapho kanyekanye kuthuthukiswa ukwakheka kwangaphakathi kwe-grain ngokusebenzisa ukuguqulwa kwe-plastic. Isenzo sokukhandwa siyayivala i-casting porosity, sihlukanise izigaba zesibili ezimfishane, futhi sihlele kabusha ukwakheka kwe-grain kube iphethini yokugeleza elandela imidwebo ye-geometric ye-coupling, ukuze insimbi eqine kakhulu ihambisane nezinkomba zokucindezeleka okukhulu kwenkonzo. Lokhu kugeleza kwe-grain kubaluleke kakhulu ezansi kwama-lugs nasezindaweni zezimpande zemisele yokukhiya, lapho amandla okugoba nokugunda egxilile khona ngesikhathi sokuhlangana kwe-quarter-turn nangaphansi kwengcindezi yamanzi eguquguqukayo. Ngenxa yokuthi insimbi iyasebenza kunokuba imane iqine, izingxenye ze-forged 6061-T6 zibonisa ukungahambisani okuncane kwangaphakathi kanye nokusabalalisa kwezibalo okuqinile kakhulu kwezakhiwo zemishini kuyo yonke i-batch yokukhiqiza, okwenza kube lula ukuthobela izindinganiso zokuhlola ingcindezi futhi kunciphise ubungozi bokwehluleka kwe-infant mortality. Nokho, inqubo yokukhandwa idinga ama-dies abizayo, izimishini zokukhandwa ezisindayo, kanye nemisebenzi eyengeziwe yokugaya ukuze kutholakale ukunemba kokugcina kwe-dimensional kanye ne-bore yangaphakathi ebushelelezi edingekayo ukuze i-gasket ihlale kahle, okukhuphula izindleko zekhoyili ngayinye. Naphezu kwentengo ephezulu, izimfuno zezempi nezemboni sekuyisikhathi eside zikhetha i-aluminium ekhandiwe kuma-fittings abalulekile ngenxa yokusebenza kwayo okubikezelwayo, futhi umkhakha wokucisha umlilo ulandela lowo mqondo ofanayo kuma-couplings okufanele asinde iminyaka eminingi yokusebenza kanzima.

Indlela yokukhiqiza inomthelela ojulile futhi olinganisekayo empilweni yokusebenza, ngoba ukuqala kokuqhekeka ngenxa yokukhathala kulawulwa yisici esikhulu kakhulu esivele sikhona engxenyeni, futhi leso sici ngokwezibalo sibi kakhulu ekwenzeni nge-casting kunasekuwenzeni nge-forging. I-Storz coupling eyenziwe nge-forging ye-6061-T6 ejikeleziswa emfuthweni othile ngokuvamile isinda imijikelezo eminingi yokulayisha ngaphambi kokuqala kokuqhekeka kune-ZL104 casting enobunjalo obufanayo, ngoba insimbi ekhutshiwe iqala ngesakhiwo esibushelelezi, esiminyene nokuqina okuphezulu kokuqhekeka. Ulwazi lwasemkhakheni lusekela lo mehluko, ngoba ama-couplings enziwe nge-forging abika amazinga aphansi okwephuka kwe-lug, ukuwohloka kwe-bore, nokuguquka kwe-gasket-seat ngemva kweminyaka yokuxhuma nokuhlukanisa okuphindaphindiwe, kanye nokuncipha kokuthambekela ekulimaleni kwentambo nokugqoka ezindaweni zokuhlangana. Ama-cast couplings, uma enziwe kahle futhi e-anodized, angahlinzeka ngokusebenza okwamukelekayo ezinhlelweni zikamasipala ezingasindi, kodwa adinga isikhathi sokuhlola esifushane namathuba aphezulu okuthatha umhlalaphansi ngaphambi kwesikhathi uma evezwe emithwalweni yokunyakazisa, ukuphambana kwentambo, noma ukusetshenziswa kabi ngabasebenzi bomlilo abasebenza endaweni engabonakali kahle. Kufanele futhi kuqashelwe ukuthi impahla ye-gasket, isimo somsila we-hose, kanye nohlelo lokugcina i-coupling kudlala indima enkulu empilweni yonke yokuhlanganiswa, ngisho noma umzimba wensimbi uqobo uhlala unamandla. Ekugcineni, inzuzo ye-forging ibonakala kakhulu ezimweni ezeqisayo zokusebenza, njengemijikelezo ephindaphindiwe yokushisa nokushisa, izimo ezinzima zomhlaba, nokulethwa kwengcindezi ephezulu yesikhathi eside, okuyilona kanye izinga lokusebenza elitholwa ngabomlilo abakhokhelwayo njalo.

Ukugqwala kuwukusabela kwe-electrochemical okuqhubeka ngezinga elinqunywa ukwakheka kwe-alloy, ukwelashwa kwendawo, umswakama, izinga lokushisa, kanye nokuba khona kwama-chloride noma amanye ama-ion anolaka, konke lokhu okukhona ezindaweni zokucisha umlilo ezihlanganisa amanzi anosawoti, ama-foam concentrates, namakhemikhali omgwaqo. I-ZL104 cast aluminum, ene-silicon-rich eutectic yayo kanye ne-micro-porosity engaba khona, ivamise ukubonisa ukugqwala okuthile okuyinkimbinkimbi, ngokuvamile ibonakala njengemigodi engaphezulu engajula futhi ixhumane phakathi nesikhathi sokusebenza esilinganiswa ngeminyaka. I-hard-coat anodizing inciphisa kakhulu lo mphumela ngokudala ungqimba olugqinsi, olunama-pores olumunca i-sealing agent futhi luvikele insimbi engaphansi, inqobo nje uma ungqimba lwe-anodizing lungalimali ngokushaywa noma ukuguguleka ngesikhathi sokuphathwa okuvamile. Ngokuphambene, i-6061-T6 inikeza ukumelana nokugqwala okuphezulu ngokwemvelo, futhi uma i-hard-coat anodized, ama-forged couplings ahlale esebenza kangcono kunezinye izindlela ze-cast ekuhlolweni kwe-salt-spray chamber nasezindaweni zangempela zasogwini. Ukuguguleka emalugini okukhiya nasebusweni be-bayonet kungenye into enciphisa impilo yokusebenza, ngoba ukunyakaza okuphindaphindiwe kwe-quarter-turn ngaphansi komthwalo kungagqwala izindawo ezishelelayo, futhi i-alloy ethambile ye-cast isengozini enkulu yokudluliswa kwempahla nokulahlekelwa okuqhubekayo kokunemba kokukhiya. Ngenxa yokuthi i-lobe egugile ingavumela ukuhlukaniswa okungaphelele ngaphansi kokudlidliza, i-coupling kufanele ihlolwe njalo, futhi indawo eqinile, efanayo ye-forged 6061-T6 ngokuvamile ilawula ukuguguleka kangcono futhi igcina ubukhulu obulinganiselwe esikhathini eside sekhalenda.

Izihlanganisi ze-Storz zomlilo zingaphansi komfutho we-hydraulic ojikelezayo njalo ngenkathi iphampu iqala, ilungisa umfutho, noma icima, futhi umjikelezo ngamunye ubeka ingcindezi ye-tensile hoop emzimbeni wokuxhuma enomthelela ekuqongeleleni kokukhathala. Ngaphansi kwe-NFPA 1963 imithetho yokudlidliza nokucindezela komjikelezo, izihlanganisi kufanele zibekezelele izinkulungwane ezingamashumi ezinkulungwane zemijikelezo kusukela kumfutho ocishe ube zero kuya kumfutho wokusebenza olinganiselwe, futhi impilo yokukhathala yengxenye ithonywa kakhulu yilungu le-alloy eliyisisekelo kanye nesimo se-residual stress eshiywe ukukhiqiza. I-ZL104 ephonsiwe ene-internal porosity iziphatha njengengxenye esivele inama-notches abukhali, ngakho amandla ayo okukhathala ancishiswa uma kuqhathaniswa namandla ayo okudonsa angaguquki, futhi imifantu ingaqala futhi isakazeke ekucindezelweni okungaphansi kwe-yield point. I-Forged 6061-T6, ngesakhiwo sayo se-fine grain nokungabikho kwe-porosity, ibonisa ijika lokukhathala eliyisicaba kakhulu, okusho ukuthi ingabekezelela imijikelezo eminingi ekuphakameni okuthile kwe-stress ngaphambi kokuthi yehluleke. Umakhenikha wokukhiya we-quarter-turn ngokwawo uhlangabezana nokugqokwa kokungqubuzana nokonakala kokuthwala umthwalo njengoba kuxhunywa ngakunye, futhi ukuguquguquka kwe-6061-T6 kuvumela ukuguquka kwendawo ukuze kusatshalaliswe kabusha ingcindezi ngaphandle kokuqala umfantu, kanti into ephonsiwe ephukayo ingaphuka ngokuzumayo. Idatha yokukhathala yesikhathi eside evela ezinhlelweni zasemkhakheni ibonisa ngokungaguquki ukuthi izihlanganisi ze-aluminium ze-Storz ezi-forged zithola izikhathi zokusebenza ezivame ukuba ngamaphesenti angama-50 noma ngaphezulu kunezilinganisi ze-die-cast zosayizi ofanayo ogunyaziwe ngaphambi kokuba zidinge ukushintshwa. Lokhu kungcono kokukhathala kuyisizathu esiyinhloko sobuchwephesha sezindleko eziphezulu zokutholwa kwezinto ezi-forged eminyangweni ebeka phambili ukwethembeka nokunciphisa izindleko zomjikelezo wempilo.

Ukuqina kwangempela emhlabeni wangempela kuhlolwa kangcono ngokuhlanganisa ukuhlolwa okusheshisiwe kwaselabhorethri kanye nokusebenza okubhaliwe emkhakheni, ngoba izimo zaselebhorethri azivamisile ukubamba ukuhlukahluka okugcwele kokuthintana okonakalisayo, udaka, iqhwa, namathuluzi awile okuhlangana nawo ukuxhuma ekusetshenzisweni kwansuku zonke. Lapho izingxenye zamahose zidonswa phezu kukakhonkolo, itshe, noma uphalt, ingaphandle lokuxhuma lithola imihuzuko engangena kungqimba olunwebekile futhi iveze i-aluminium eluhlaza, futhi lapha ukumelana nokugqwala okungokwemvelo kwe-6061-T6 kunikeza inzuzo ephusile ngaphezu kwe-ZL104. Ukumelana nomthelela kuyaboniswa lapho ukuxhuma kushaya umlomo we-hydrant yensimbi ngesikhathi sokuxhuma okusheshayo, futhi ukunwebeka okuphezulu kwe-6061-T6 kunciphisa amathuba okuphuka okuyinhlekelele kuyilapho kugcina ikhono lokwenza ukuvala okungavuzi okwesikhashana. Iminyango egcina ukuxhuma kuma-reel amathuluzi nayo ibeka emithwalweni yokudlidliza ende, engakwazi ukuvula ama-gasket futhi ikhuthaze ukugqoka kokuhlikihla emsileni wehose, futhi ukulawula okunembile kobukhulu bezingxenye ezikhohlisiwe kusiza ukugcina ukufana okungaguquki kokungenelela okumelana nokuvuleka ngokuhamba kwesikhathi. Amathimba okunakekela abika ukuthi ukuxhuma okukhohlisiwe akuthambekele kangako ekubambeni ngemva kokuchayeka isikhathi eside emanzini anosawoti, ngoba ingaphezulu elikhohlisiwe alikhuli imigodi ejulile ebamba umswakama onosawoti futhi isheshise ukugqwala kwemifantu. Ngaphezu kwempilo yesevisi elinganiselwe yeminyaka eyishumi kuya kwengamashumi amabili, izindleko zizonke zobunikazi bokuxhuma okukhohlisiwe kwe-6061-T6 zingakwazi ukuqhudelana ne-ZL104 ephonsiwe uma ukushintshwa ngaphambi kwesikhathi, isikhathi sokuma komsebenzi, nokonakala kwamahose kufakwa ekuhlaziyweni kwezomnotho.

Ukuhlolwa kwengcindezi yamalunga amapayipi omilio kulawulwa amazinga agunyaziwe achaza imingcele emincane yokusebenza, izinqubo zokuhlola, kanye nemibandela yokwamukelwa, kanti i-NFPA 1963 iyona ndlela eyinhloko eNyakatho Melika yamalunga amapayipi omilio. Izinga lihlanganisa izidingo zobukhulu, imikhawulo yokuvuza, amazinga okugqabhuka kwengcindezi, kanye nemvamisa yokuhlola, futhi libeka izinga lokusebenza lengcindezi elivamise ukuba ngama-400 psi kumapayipi okuhlinzeka omilio, kuyilapho lidinga ukuthi amalunga amelane nengcindezi yokugqabhuka engaphezu kwalelo zinga lokusebenza. I-Underwriters Laboratories (UL) nayo ishicilela izidingo zokusebenza zamalunga okulwa nomlilo, futhi abakhiqizi abafuna ukubhaliswa kwe-UL kumele babonise ukuthobela ngokuhlolwa okuzimele kwamasampula amele ukukhiqizwa. Ezimakethe eziningi zamazwe ngamazwe, amazinga engeziwe afana ne-EN 14420 noma okulingana nawo esifundeni abeka izimfuno ezifanayo zokuqinisekisa, futhi i-coupling ethunyelwa emhlabeni wonke kufanele ngokufanelekile ithwale izimpawu eziningi zokuthobela ukuze yanelise iziphathimandla ezahlukahlukene. Ukuhlolwa kwengcindezi ngokwako kungumcimbi wokulimaza noma wokufakazela lapho ukuhlanganiswa kwe-coupling kuvalwa, kugcwaliswa ngamanzi, futhi kufakwa ingcindezi kancane kancane ngenkathi amathuluzi okulinganisa erekhoda ukuwohloka, ukuvuza, kanye nengcindezi lapho ukwehluleka kwenzeka khona. Izinhlangano eziqinisekisayo nazo zihlola i-coupling ngaphansi kwezimo zengcindezi ezijikelezayo, ukushintsha kokushisa, kanye nokushaqeka kwemishini ukuze zilingise impilo yangempela yokusebenza, ngoba i-coupling edlula ukuhlolwa okukodwa kokugqabhuka okungaguquki ingahluleka ngaphambi kwesikhathi ngaphansi komthwalo wokukhathala. Lawa mazinga asungula ulimi olufanayo phakathi kwabathengi nabakhiqizi, okuvumela abaphathi bokuthenga ukuthi bacacise izinga elincane lokugqabhuka kwengcindezi ngentembelo yokuthi umkhiqizo uqinisekiswe ngokuzimele.

Ukuqhathanisa ingcindezi yokusebenza nengcindezi yokuqhuma phakathi kwe-ZL104 ecatshangelwayo kanye ne-6061-T6 eforjiweyo kumele kuhlolwe ngokucophelela ubukhulu bodonga, ukuma kwesigaba esiphambanayo, kanye nekhwalithi yeqoqo elithile lokukhiqiza, ngoba ukucatshangelwa kodonga olukhulu kungase kudlule ukufakwa kodonga oluncane nakuba ama-alloys ehluka emandleni angaphakathi. Ezimweni zokuhlola ezijwayelekile ezisebenzisa ubukhulu obulinganayo obucatshangelwayo kanye nemiklamo eqhathanisekayo, ama-couplings e-6061-T6 aforjiweyo ngokujwayelekile abonisa ingcindezi yokuqhuma ephakeme ngamaphesenti angu-20 kuya kwangu-40 kunalawo e-ZL104 acatshangelwayo ngesisindo esifanayo, okubonisa kokubili amandla aphakeme okudonsa kanye nokuvumelana okukhulu kwe-alloy ekhohlisiweyo. Umzimba we-Storz coupling ongu-2.5-intshi omelelayo we-6061-T6 aforjiweyo ungase ubonise ingcindezi yokuqhuma ephakathi kuka-2,800 kuya ku-3,400 psi, kuyilapho i-ZL104 die-cast coupling eyenziwe kahle yosayizi ofanayo ivamise ukuqhuma phakathi kuka-1,900 no-2,500 psi kuye ngezinga le-porosity. Izilinganiso zengcindezi yokusebenza azihluki kangako ngoba amazinga avimbela ingcindezi yokusebenza evumelekile ngokuqapha ngokusekelwe kusampula yokukhiqiza ebuthakathaka kakhulu, kodwa izinga eliphezulu lokuphepha elikhona ekwakhiweni okuforjiweyo livumela umnyango ukuthi usebenze eduze nomthamo wempompo ngaphandle kokukhathazeka ngamaphutha acashile okucatshangelwa. Ukuhlolwa kwengcindezi yobufakazi ngokuphindwe ka-1.5 kwengcindezi yokusebenza kuyisinyathelo esijwayelekile sokuqinisekisa, futhi ama-couplings aforjiweyo ahlala ephumelela izivivinyo ezinjalo ngokuhlukana okuncane, kuyilapho izingxenye ezicatshangelwayo zingase zibonise ukuvuza ngezikhathi ezithile ezihlalweni ze-gasket okudinga ukwenqatshwa. Le miphumela ebhaliwe yokuhlola ibalulekile eminyangweni yezomlilo ngoba inquma ukuthi ingakanani amandla okugcina asele ngaphambi kokuqhuma okuyinhlekelele, ikakhulukazi ezimweni ezinjengokumpompa okudluliselayo lapho izimoto zomlilo eziningi ziphushela amanzi ngokulandelana emgqeni owodwa wokuhlinzeka.

Imininingo eshicilelwe yokuhlolwa evela kumalabhorethri azimele kanye namarekhodi ekhwalithi yomkhiqizi aveza iphethini engaguquki: izinga lokucindezela kokuqhuma kwe-forged 6061-T6 Storz coupling alizweli kakhulu ekushintsheni kokukhiqiza kunale ye-cast ZL104 unit, okwenza umkhiqizo we-forged ube nokubikezela okungcono ekuthengeni okukhulu. Ekuhlolweni okukodwa okuqhathanisayo kwamacoupling angu-2.5-inch, amasampula amahlanu e-forged 6061-T6 aqhuma ngokucindezela kusukela ku-2,950 kuya ku-3,180 psi, okumele ukusabalala okucishe kube ngamaphesenti ayisishiyagalombili, kuyilapho amasampula amahlanu e-cast ZL104 ahluka kusukela ku-2,050 kuya ku-2,420 psi, ukusabalala okubanzi okucishe kube ngamaphesenti ayishumi nesishiyagalombili okukhombisa umthelela we-internal porosity. Ukuhlolwa kokukhathala okuvamile ocwaningweni olufanayo kwabeka zombili izinto ekucindezelweni kwemijikelezo engu-200,000 kusukela ku-0 kuya ku-400 psi, futhi nakuba wonke amasampula asinda, izinhlaka ze-cast zabonisa ukukhula okulinganisekayo kobukhulu kanye nezinkomba zemicrack etholakalayo ezingazange zibonakale kumasampula e-forged. Ukuhlolwa kokuvuza ngomfutho olinganiselwe wokusebenza ongu-400 psi akuzange kuveze ukwehluleka kunoma iyiphi iqembu lezinto, okukhombisa ukuthi zombili izingxube zanele ekusebenzeni okujwayelekile komasipala, kodwa ukuhlaziywa kwemajini kusekele ngokucacile idizayini ye-forged ngaphansi kwezimo zokushisa okuphezulu. Kubalulekile ukuqaphela ukuthi ikhwalithi yokwelashwa ngokushisa, ubukhona bama-aluminium oxide films wesibili, kanye nokunemba kokwenziwa kwe-gasket groove kungashintsha umphumela womkhiqizo othile, ngakho abathengi kufanele ngaso sonke isikhathi bacele izitifiketi zamabhetshi kanye nemibiko yokuhlolwa yomuntu wesithathu kunokuba bathembele kuphela kudatha ye-alloy evamile.
