Uma kukhulunywa ngezinhlelo zamapayipi omlilo, ukukhetha isixhumi esifanele kuyisinqumo esibalulekile esithinta ngqo ukusebenza kahle, ukuphepha, nokuqina kwemishini. Izinsiza zamapayipi omlilo njenge-GOST ne-Rotta zimelela izindinganiso ezimbili ezisetshenziswa kakhulu emikhakheni yezimboni kanye nokulwa nomlilo emhlabeni wonke. Lezi zinhlobo ezimbili ezihlukene zokuxhuma zisebenza izinjongo ezifanayo kodwa zisebenza ngezimiso ezihlukene kakhulu zokuklama okufanele abachwepheshe bakuqonde ngaphambi kokuthenga. Izixhumi ze-GOST zivela ezindinganisweni zaseRussia futhi zine-mekanizimu yokuxhuma enezintambo enikeza ukuvaleka okuhle kakhulu ngaphansi kwengcindezi ephezulu, kanti izixhumi ze-Rotta zilalela izincazelo ze-German DIN 14366 futhi zisebenzisa uhlelo lokukhiya lwe-bayonet oluvumelanayo ukuze kusetshenziswe ngokushesha. Ukukhetha phakathi kwezinhlelo ezimbili kuncike ezintweni ezahlukahlukene okubandakanya imvelo yesicelo esithile, izilinganiso zengcindezi ezidingekayo, ukuhambisana kwamapayipi, kanye nendlela yokusebenza yeqembu lokulwa nomlilo. Ochwepheshe embonini yezokuphepha komlilo kufanele bahlole ngokucophelela lezi zihlukahlukene ukuze baqinisekise ukuthi bakhetha isixhumi esifanele kakhulu izidingo zabo ezithile kanye nokucushwa kohlelo. I-Varicpand International izibeke njengomphakeli omethembayo wezindinganiso zombili, enikeza uhla olubanzi lwezixhumi ezisezingeni eliphezulu ezihlangabezana nezidingo eziqinile zokusebenza zomhlaba wonke.

Ukuqonda umehluko oyinhloko phakathi kwezixhumi ze-GOST neze-Rotta kuyisinyathelo sokuqala sokwenza isinqumo sokuthenga esinolwazi kunoma yiluphi uhlelo lokuvikela umlilo noma lokudlulisa uketshezi lwezimboni. Imishini yokucisha umlilo kufanele isebenze ngokuthembekile ngaphansi kwezimo ezinzima, ngakho-ke ukukhethwa kwesixhumi kuthinta ngqo ukuthi amaqembu angakwazi yini ukuphendula kahle ezimeni eziphuthumayo nokugcina ukugeleza kwamanzi okungaguquki. Ubukhulu obujwayelekile be-DN50, i-DN70, ne-DN150 baphakathi kobukhulu obucelwa kakhulu, ngalinye lisebenza umthamo othile wokugeleza nobubanzi besicelo abachwepheshe okufanele babufanise namapayipi abo kanye nezidingo zengcindezi. Lo mhlahlandlela ophelele uzokuhambisa ngokusebenzisa umehluko oyisisekelo, imininingwane yobukhulu, izinketho zezinto, kanye nezidingo zezesekeli ukusiza abathengi ukuthi bathole isixazululo esihle kakhulu endaweni yabo yokusebenza. Ekupheleni kwalesi sihloko, abaphathi bokuthenga, onogada bezokuphepha komlilo, kanye nonjiniyela bokulungisa bazoba nenkambiso ecacile yokuhlola izixhumi ze-GOST neze-Rotta kuzo zonke izigaba ezidume kakhulu zobukhulu.

Ama-coupling we-GOST enziwa ngokuhambisana namazinga ombuso waseRussia futhi aziwa kakhulu ngokwakhiwa kwawo okuqinile kwezintambo okuletha ubuqotho obuhle bokubopha ngaphansi kwezimo zengcindezi ephezulu. Lawa ma-coupling ezimboni avame ukuba nezingxenye zokubopha zesilisa nezabesifazane ezijikijelwa ndawonye ngokuvikelekile, kudale ukubopha kwensimbi-kuya-ensimbi okwazi ukumelana nengcindezi yokusebenza efika ku-40 bar ezimweni eziningi. Izinto zokubopha ezijwayelekile ze-GOST ngokuvamile zenziwa ngensimbi eqinile noma ithusi, zinikeza amandla amakhulu emishini nokumelana nokuhlanekezelwa ngesikhathi sokuxhuma nokukhipha izikhathi eziningi. Indlela yokubopha idinga imizuzwana embalwa eyengeziwe ukuxhuma uma kuqhathaniswa nezindlela zokuxhuma ngokushesha, kodwa inikeza inzuzo yokuxhumana okungazamazamiswa okungeke kuxhumeke ngephutha ngaphansi kwezimo zokusebenza eziyinselele. Izindawo ezimbonini ezisindayo njengezimayini, izindawo ezinkulu zokukhiqiza, kanye nezinhlelo zokuhlinzekwa kwamanzi kamasipala zivame ukukhetha ama-coupling we-GOST ngenxa yokwethembeka kwawo okufakazelwe ezinhlelweni zokusebenzisa njalo. Ochwepheshe kufanele baqinisekise ukuthi i-pitch nokubanzi kwezintambo ziyahambisana ngokunembile phakathi kwe-coupling kanye ne-hose fitting ukugwema ukuvuza noma ukuhluleka kokuxhuma ngesikhathi sokusebenza okubalulekile. Izinga le-GOST lwamukelwe kabanzi kulo lonke i-Eastern Europe, iRussia, kanye nezingxenye zase-Asia, okwenza kube ukucaciswa okubalulekile ezinhlanganweni ezisebenza noma ezithola izinto zokusebenza kulezi zifunda.

Kokubili izixhumi ze-GOST neze-Rotta zitholakala ngezinto ezahlukahlukene, futhi ukukhetha i-alloy efanele kubaluleke njengokukhetha indinganiso yokuxhuma uqobo ukuze kuqinisekiswe ukwethembeka kwesistimu yesikhathi eside. Izixhumi ze-GOST ezinsimbi zinikeza amandla aphezulu emishini futhi zilungele ukufakwa unomphela noma okungapheli lapho isisindo singeyona into ebalulekile, kanti izixhumi ze-GOST ezithusi zinikeza ukumelana okungcono nokugqwala ezindaweni zasolwandle noma ezimanzi. Izixhumi ze-Rotta ezakhiwe nge-aluminum forge zinikeza isilinganiso esihle kakhulu samandla-kuya-esisindo esinciphisa ukukhathala komsebenzisi phakathi nemisebenzi yomlilo ende lapho amaqembu kufanele athwale ubude obukhulu bemibhobho nemishini. Izinhlobo zensimbi engagqwali zazo zombili izindinganiso ziyatholakala ezinhlelweni ezibandakanya amakhemikhali anolaka, ukwelashwa kwamanzi amdaka, noma izindawo zokucubungula ukudla lapho inhlanzeko nokumelana nokugqwala kubaluleke kakhulu. Ibanga lokucindezela lokusebenza liyahluka phakathi kwezindinganiso ezimbili, nge-GOST ejwayele ukukalwa ngamabanga aphezulu afika ku-40 bar, kanti izixhumi ze-Rotta ngokuvamile zikaliwe phakathi kuka-16 no-25 bar kuye ngosayizi kanye nokucaciswa kwempahla. Ukuqonda lezi zici zezinto kanye nokucindezela kuvumela abathengi ukuthi bahambisane nesixhumi hhayi kuphela nobubanzi bemibhobho kodwa futhi namakhemikhali athile, okushisayo, kanye nezidingo zemishini zendawo yesicelo sabo.

Ukukhetha usayizi ofanele wokubopha izivunguvungu zomlilo kubalulekile ukugcina amanzi kahle futhi kuqinisekise ukuhambisana nezivunguvungu ezikhona, imilomo, nemishini yokumpompa kunoma yiluphi uhlelo lokuvikela umlilo. Usayizi we-DN50 uhambisana nomgodi ongama-intshi angu-2 ovame ukubhanqaniswa nezivunguvungu zomlilo ezingama-millimeter angu-52, okwenza kube ukukhetha okujwayelekile kwemigqa yokuhlasela, ama-booster reels, kanye nezinhlelo zokudiliva ezincane lapho ukuhambisa kubalulekile. Kuzivunguvungu ze-DN50 Rotta, ibanga ukusuka endaweni eyodwa kuya kwenye (lug-to-lug) lingama-millimeter angu-66, kanti imininingwane yokubopha ye-GOST ingama-M64x2, okubhekisela kumgodi onama-millimeter angu-64 one-pitch engu-2 millimeter okufanele uqeqeshwe ngokunembayo ukuze kuqinisekiswe ukuxhumana okungavuza. Ukudlulela ku-DN70, okuyingxenye engama-intshi angu-2.5 eyenzelwe izivunguvungu ezingama-millimeter angu-70, ochwepheshe bazothola ukuthi izivunguvungu ze-Rotta zidinga ibanga le-lug elingama-millimeter angu-89, kanti izivunguvungu ze-GOST zisebenzisa i-M76x2 threading ukuze ziqine ngaphansi kwezimo zokugeleza okuphezulu. Usayizi we-DN150 uyikakhulu kulawa amathathu, unikeza umthamo womgodi ongama-intshi angu-6 ongasekela ukugeleza okukhulu kwamanzi kwemigqa yokuhlinzekwa kwama-hydrant, imilomo yokuqapha, kanye nezinhlelo ezinkulu zokucisha umlilo ezimbonini lapho umthamo uyinto ebaluleke kakhulu. Kuzivunguvungu ze-DN150 Rotta, ibanga le-lug landa libe ngama-millimeter angu-133, kanti inguqulo ye-GOST inokubopha okukhulu kwe-M156x3 okudinga ukuphathwa ngokucophelela ngesikhathi sokufakwa ukuze kugwenywe ukubopha okungalungile nokulimala okungase kube khona kwesithiyo. Ithebula elilandelayo lihlinzeka ngereferensi ehlanganisiwe yezici ezibalulekile zobukhulu nokucindezela kuzo zonke izinhlobo ezintathu ukuze kusizwe amaqembu okuthenga ekuqinisekiseni ukuhambisana nemihlangano yabo yezivunguvungu ekhona nezidingo zokusebenza.

Uma ubuyekeza ithebula elingenhla, ochwepheshe kufanele baqaphele ukuthi izilinganiso zengcindezi ziyizindinganiso eziphakeme kakhulu futhi ingcindezi yangempela yokusebenza kufanele ihlale iqinisekiswa ngokumelene nesitifiketi somkhiqizi esithile samamodeli ngamunye we-coupling kanye nezinga lezinto. Umehluko wobukhulu phakathi kwama-coupling aseRotta kanye ne-GOST kuwo wonke usayizi ofanayo kusho ukuthi ama-adapter avame ukudingeka lapho uhlanganisa imishini kusuka kuzo zombili izindinganiso ohlelweni olulodwa lwe-fire hose noma inethiwekhi yokuhlinzekwa kwamanzi. Abasebenzi abasebenza ngosayizi be-DN50 kanye ne-DN70 bazothola ukuthi lezi zigaba ezimbili zihlanganisa iningi kakhulu lezimo zokulwa nomlilo ezisebenzisa isandla, kanti i-DN150 igcinelwe izimo zokuhlinzekwa kwevolumu ephezulu kanye nokufakwa okumile lapho isilinganiso sokugeleza kunokuba lula khona siyisici esihamba phambili sokuklama. I-Varicpand International incoma ukuthi abathengi bahlale beqinisekisa ububanzi bangaphakathi be-hose kanye nokujiya kodonga ngaphambi kokuqeda ukukhethwa kwe-coupling, njengoba ukuhluka okuncane ekubekezeleleni kokukhiqizwa kwe-hose kungathinta ukusebenza kokubeka uphawu kuzo zombili izinhlobo ze-quick-connect kanye ne-threaded coupling. Izinhlangano ezigcina izimoto zemishini ezindaweni eziningi zingazuza ngokujwayela umndeni owodwa we-coupling, kodwa ukuguquguquka kokusebenzisa ama-adapter kuqinisekisa ukuthi izinselelo zokusebenza ndawonye zingaphathwa ngempumelelo ngaphandle kokudela ukulungela kokusebenza.

I-Varicpand International yakhe idumela eliqinile emakethe ezinto zokucisha umlilo nezokuxhuma izimboni ngokuhlinzeka njalo ngemikhiqizo ehlangabezana noma edlula amazinga ekhwalithi yamazwe ngamazwe ngokuhlolwa okuqinile nezinqubo zokukhiqiza eziqondile. Uhla lwenkampani lwezixhumi ze-GOST ne-Rotta luhlanganisa izinketho zensimbi ye-aluminum, ithusi, ne-stainless steel, zonke ezihlolwa ngokucophelela ukuze kuqinisekiswe ukunemba kobukhulu, ubuqotho bezinto, kanye nekhono lokubamba ingcindezi ngaphambi kokuba ziphume efektri. Isixhumi ngasinye esenziwe yi-Varicpand senzelwe ukuthi sihambisane nemikhiqizo emikhulu yomhlaba, siqinisekisa ukuthi abasebenzisi bokugcina bangathola izingxenye ezithembele kuzo nezokushintsha ngaphandle kokuboshwa ezinhlelweni eziyimfihlo ezilinganiselayo ukuguquguquka kwabo kokuthenga.
