Umbhobho wokupholisa usebenzisaityhubhu yentsimbi engenamthungokufuneka isetyenziswe njenge-welding, ukongeza ekusebenziseni xa iqhagamshelwe kwisixhobo, iivalvu eziphothiweyo okanye ezinentambo.ukuwelda kwerhasi usebenzisa i-diameter engaphantsi kwe-5mm, ubukhulu obukhulu kune-5mm usebenzisa ukuwelda.I-pipe welding isetyenziswa ngokuqhelekileyo kwifriji, kuphela xa kuyimfuneko ngokubhekiselele kufakelo kunye nokugcinwa, ukudibanisa i-flanged okanye i-threaded isetyenziswa.Ukusebenzisa i-convex surface flat welding flange isikwere iflange okanye i-flange emile okwezintso, xa uqhagamshelo lweflange, iigaskets ezinobunzima obuyi-1 ~ 3mm yerubha ye-asbestos yeoli, kunye nokumodareyithwa kwegraphite eqatywe ngeoyile.Xa udibaniso oluthungelweyo, kufuneka usebenzise i-petroli okanye i-kerosene ukucoca ioli kwimicu, kwaye emva koko ifakwe nge-glycerol ukulungelelanisa ukutya kwe-gluten okanye i-teflon tape njenge-packing yetywina, inqatshelwe ukusetyenziswa kwelothe njengeoli yeflakisi kunye nokupakishwa kwetywina.

Ububanzi bombhobho wefriji yeFreon bungaphantsi kwama-25 mm kunye nombhobho wobhedu, kukho iindlela ezininzi zokudibanisa.

(1) amaqhekeza obhedu agqityiweyo.ifom yojongano yohlobo lwesokethi, uqhagamshelo lokubrawuza.

(2) Isokethi eqhagamshelwe ngokujongisa ubhedu, i-annealing kufuneka iqale iphele umbhobho, kwaye ke ukufudumeza ukungunda kunye nesokethi, idayamitha yesokethi kufuneka ibe nkulu kunobubanzi obungaphandle betyhubhu yofakelo 0.25 ~ 0.5mm, ubunzulu obusebenzayo besokethi ilingana nedayamitha yombhobho, indlela yokunyuka Ukukhangela ukuhamba okuphakathi.

(3) uqhagamshelwano lweflange.Ngokweemfuno zoyilo kunye neemeko ezithile, imisebenzi yofakelo lwemibhobho ingasetyenziselwa ubhedu kunye ne-alloy pipe ye-alloy flange flange evulekileyo, i-welding ring flange ekhululekile kunye ne-welded flange, ifom yokudibanisa i-welded.
