Ukupholisa ipayipi usebenzisaithubhu yensimbi engenamthungokufanele isetshenziswe njenge-welding, ngaphezu kokusetshenziswa uma ixhunywe kumishini, ama-valve ane-flanged noma uxhumano oluxhunyiwe.ukushisela igesi kusetshenziswa ububanzi obungaphansi kuka-5mm, ububanzi bukhulu kuno-5mm kusetshenziswa ukushisela.I-pipe welding ivame ukusetshenziswa esiqandisini, kuphela uma kunesidingo mayelana nokufakwa nokugcinwa, uxhumano lwe-flanged noma i-threaded lusetshenziswa.Kusetshenziswa i-convex surface flat welding flange flange eyisikwele noma i-flange emise okwezinso, lapho ixhunywa i-flange, ama-gaskets anogqinsi lwe-asbestos yerabha kawoyela engu-1 ~ 3mm, kanye nokuguquguquka kwe-graphite egcotshwe ngamafutha.Lapho uxhumano olucushiwe, kufanele usebenzise uphethiloli noma uphalafini ukuhlanza uwoyela ezintanjeni, bese umbozwa nge-glycerol ukuze uhlanganise okuphakelayo kwe-gluten noma i-Teflon tape njengendlela yokupakisha uphawu, kwenqatshelwe ukusetshenziswa komthofu njengamafutha efilakisi nokupakisha uphawu.

Ububanzi bepayipi lesiqandisi se-Freon bungaphansi kuka-25 mm ngepayipi lethusi, kunezindlela eziningana zokuxhuma.

(1) izingcezu zethusi eziqediwe.ifomu lesixhumi esibonakalayo sohlobo lwesokhethi, uxhumano lwe-brazing.

(2) isokhethi exhunywe nge-brazing yethusi, i-annealing kufanele iqale iphele ipayipi, bese ifudumeza isikhunta ngesokhethi, ububanzi besokhethi kufanele bube bukhulu kunobubanzi obungaphandle beshubhu lokufaka 0.25 ~ 0.5mm, isokhethi ukujula okuvumelekile kungaba ilingana nobubanzi bepayipi, isiqondiso esikhuphukayo Ibheka ukugeleza okuphakathi.

(3) uxhumano lwe-flange.Ngokwezidingo zokuklama kanye nezimo ezithile, imisebenzi yokufaka ipayipi ingasetshenziselwa ipayipi le-alloy yethusi ne-copper alloy flange flange, indandatho yokushisela i-flange exekethile kanye ne-welded flange, ifomu lokuxhuma elihlanganisiwe.
