Uhloboyizingxenye ezenziwe nge-disk ezisetshenziswa kakhulu kumapayipi.Uhlobozisetshenziswa ngababili nangokufanauhlobokuma-valves. E-Pipeline Engineering,uhlobozisetshenziselwa ikakhulukazi ukuxhumana kwamapayipi. Esidlekelini sokuxhuma ipayipi, zonke izinhlobo zokufakwa kwe-flange, ipayipi eliphansi lokucindezela zingasebenzisa ucingoi-flange, ukusetshenziswa kwe-welding flange ngaphezu kwamakhilogremu ama-4 wengcindezi. Engeza ukubopha uphawu phakathi kwamabiliuhlobo, bese uqinisa nge-bolt.UhloboNgezingcindezi ezahlukene zinobukhulu obuhlukile futhi usebenzise ama-bolts ahlukile.

Uma kuqhathaniswa nensimbi yekhabhoni, insimbi engenasici inezici ezilandelayo:
1) Izinga elibi likagesi eliphakeme, cishe izikhathi ezi-5 zensimbi yekhabhoni.
2) I-coefficion enkulu yokunwebeka, i-40% enkulu kunensimbi yekhabhoni, futhi ngokwanda kwamazinga okushisa, ukunwetshwa kokwenyuka okuqondile kwenani kukhuphuke ngokufanele.
3) Ukuqhutshwa okuphansi okushisayo, cishe 1/3 wensimbi yekhabhoni.
Qaphela:
1. Ukuze uvikele ukugqwala phakathi kwamehlo ngenxa yokushisa kwesembozo se-flange, i-welding yamanje akufanele ibe nkulu kakhulu, cishe ama-20% ngaphansi kwe-arcon yensimbi, i-arc akufanele ibe yinde kakhulu, ukupholisa okusheshayo Phakathi kwezendlalelo, futhi ubuhlalu obuncane beleveli bufanele.
I-2 Ukuqhekeka kanye ne-flake), ukuvikela i-electrode coating amafutha amafutha nokunye ukungcola, ukuze ungandisi okuqukethwe kwekhabhoni yomthungo we-welding futhi kuthinte ikhwalithi yezitho ze-welding.

3.i-flangeI-Pipe Welding, ngokuphindaphinda kwe-carbide ye-carbide ye-carbide, yehlisa ukumelana nokugqwala kanye nezakhiwo zemishini.
4. Chromei-flangeUkufakelwa ngemuva kwe-welding harning american flange evamile yaseMelika inkulu, kulula ukuqhekeka. Uma uhlobo olufanayo lwe-chromium steel engaseki i-electrode yensimbi (G202, G207) i-welding, kufanele yenziwe ngenhla kwama-300 ℃ Preheating futhi cishe ngo-700 ℃ ngemuva kokwelashwa okupholile kancane. Uma i-weldentiment ingakwazi ukwelashwa ngemuva kokushiswa, i-flanged electrode yamapayipi (A107, A107) izosetshenziswa.
5.i-flange, ukuze kuthuthukiswe ukumelana nokugqwala kanye nokushayisana futhi kwandise inani elifanelekile lezinhlobo zokuqina TI, NB, MO, njll. Lapho usebenzisa uhlobo olufanayo lwe-Chromium Flange Electrode (G302, G307), kufanele lube shukunyiswa lube yize ngaphezulu kwama-200 ℃ futhi lususwe ngemuva kokufudumala cishe nge-800 ℃. Uma i-welderment ingakwazi ukushiswa ukushisa, i-flanged welding electrode (A107, A107) kufanele isetshenziswe.
6.-VuvukeleUkufakwa kwamapayipi, inkinobho-i-weldingi-flangeI-Electrode inokumelana kahle nokuphikiswa kokogqwala kanye nokumelana ne-oxidation, kusetshenziswe kabanzi kumakhemikhali, umanyolo wamakhemikhali, u-petroleum, ukukhiqiza imishini yezokwelapha.
