Ngakho-ke, lapho ukhetha i-camlock yokusebenza ngaphansi kwengcindezi ephezulu, kubalulekile ukukhetha impahla ye-gasket ehambisana ngokugcwele nokwakheka koketshezi kanye nobubanzi bokushisa kokusebenza.

Isitifiketi se-EN14420-7 siyadingeka futhi siyanconywa kakhulu kuma-camlock couplings athengiswa eYurophu, ngoba sisungula izimfuneko ezifanayo zobukhulu, izinto zokwakha, nokuhlolwa eziqinisekisa ukuphepha, ukushintshana, nokwethembeka. Leli zinga libhekiselwa kulo emithethweni ehlukahlukene yaseYurophu nakwimihlahlandlela yezimboni, futhi abasebenzisi abaningi bokugcina, onjiniyela abayeluleki, nezinhlaka ezilawulayo ziyakugcizelela ukuthobela le mfuneko ezinhlelweni zokudlulisa uketshezi olunomfutho. Ama-couplings aqinisekisiwe abhekana nokuhlolwa okuqinile kwengcindezi ye-hydrostatic, ukuhlolwa kokuvuza, nokuhlolwa kobukhulu ukuze kuqinisekiswe ukuthi ahlangabezana nezimfuneko ezishiwo. Ukuthenga ama-camlocks aqinisekisiwe nge-EN14420-7 kumthengisi ohloniphekile njenge-Varicpand kuqinisekisa ukuthobela imithetho futhi kunikeza isiqinisekiso sekhwalithi esibhaliwe esivikela ibhizinisi lakho.

Ama-camlock couplings e-aluminium ngokuvamile alinganiswa ukuthi asebenze ngomfutho omkhulu ofinyelela ku-16 bar, okuhambisana nesilinganiso somfutho se-PN16 ngaphansi kwezinga le-EN14420-7. Lesi silinganiso esiphansi ngokuqhathaniswa sibonisa amandla emishini aphansi ngokuphelele wezingxubevange ze-aluminium uma kuqhathaniswa nensimbi engagqwali noma ithusi, kanye nokucatshangelwa mayelana nokuqhekeka kwe-stress corrosion ezindaweni ezithile. Noma kunjalo, ama-aluminium camlocks athandwa kakhulu ezinhlelweni lapho ukwakhiwa okulula kuyinto ebalulekile, njengokunisela kwezolimo, ukubekwa kwamapayipi okwesikhashana, amasistimu okucisha umlilo, kanye nemisebenzi yokudlulisa ehambayo. Ezinhlelweni ezidinga imfutho ephakeme, ukukhetha i-camlock yensimbi engagqwali noma yethusi ohlwini olubanzi lwemikhiqizo ye-Varicpand kungaba yikho okufanele.

Izinga lokushisa elisebenzayo lithinta isigaba sokucindezela kwe-camlock ngokwezinga lezinto ezisetshenziswayo ngoba izinto eziningi, ikakhulukazi ama-thermoplastics nama-elastomeric gaskets, zilahlekelwa amandla emishini nokuqina lapho izinga lokushisa likhuphuka. I-polypropylene camlock elinganiselwe ku-10 bar ku-20°C lingadinga ukwehliswa kwezinga lalo kakhulu ukuze lisebenze ku-60°C noma ngaphezulu, ngoba i-polymer iyathamba futhi ibe sengozini yokukhukhumala nokuguquka ngaphansi kwengcindezi eqhubekayo. Ngokufanayo, ama-rubber gaskets angaba lukhuni, avuvukele, noma abe buthaka emazingeni okushisa aphakeme, okubeka engcupheni ukuvaleka kokuxhumana. I-stainless steel nethusi zigcina izakhiwo zazo zemishini emazingeni okushisa aphakeme kakhulu kangcono kune-aluminium nama-thermoplastics, kodwa ekugcineni zonke izinto zidinga ukwehliswa kwezinga ngokuya ngezinga lokushisa, ngakho-ke hlala ubonisana namashadi wezinga lokushisa nengcindezi omkhiqizi ngaphambi kokuqeda ukukhetha kwakho.

Ngokwezinga lokucindezela okubizwa nge-nominal pressure rating, zombili izixhumanisi ze-camlock ze-SS304 ne-SS316 zivame ukukalwa ukuthi zisebenze ngomfutho omkhulu ongafika ku-25 bar, njengoba zombili lezi zinsimbi zinamandla afanayo okudonsa. Nokho, umehluko omkhulu usekumelaneni nokugqwala (corrosion resistance) kunamandla okucindezela, njengoba i-SS316 iqukethe i-molybdenum enikeza ukumelana okuphezulu nama-chloride, ama-acid, nendawo enosawoti. Ezimweni ezigqwala kakhulu, isixhumanisi se-SS316 sizogcina ukuqina kwaso nokulinganiselwa komfutho isikhathi eside kunese-SS304, okungenzeka sithinteke nge-pitting corrosion ekugcineni inciphise amandla aso asebenzayo. Ngakho-ke, nakuba izinga lomfutho lifana, i-SS316 ivame ukukhethwa ezinhlelweni zasolwandle, zamakhemikhali, nezemithi lapho ukumelana nokugqwala kubaluleke kakhulu.

Izihlanganisi ze-camlock ezenziwe nge-polypropylene zifanele ukusetshenziswa emisebenzini enomfutho ophansi kufika ku-10 bar, okuhambisana nesilinganiso somfutho se-PN10, uma nje izinga lokushisa lokusebenza lihlala ngaphakathi kwemikhawulo yezinto zokwakha, ngokuvamile ngaphansi kuka-80°C. Zisetshenziswa kabanzi ezinhlelweni zokulinganisa amakhemikhali, imishini yaselabhorethri, izindawo zokuhlanza amanzi, kanye nemigqa yokudlulisa enomfutho ophansi lapho ukumelana kwazo okuhle kakhulu nezinhlobonhlobo zamakhemikhali kudlula amandla azo aphansi emishini. Kubalulekile ukuqinisekisa ukuthi uketshezi alulimazi into ye-polypropylene nokuthi i-gasket ihambisana nakho kokubili uketshezi kanye nezinga lokushisa. Ezinhlelweni ezidinga imfutho ephezulu, kunconywa ukukhetha ama-camlock ensimbi afana ne-stainless steel noma ithusi.
