1. Ukushisela okuyisicaba: kuphela i-welding ungqimba lwangaphandle, akudingeki ukuthi ushise ungqimba lwangaphakathi;Ngokujwayelekile esetshenziswa emigqeni yengcindezi ephakathi nendawo kanye nephansi, umfutho ojwayelekile wokufakwa kwamapayipi kufanele ube ngaphansi kuka-2.5mpa.Kunezinhlobo ezintathu zokubekwa uphawu kwendawo yokushisela eyisicaba, uhlobo olubushelelezi ngokulandelana, uhlobo lwe-concave ne-convex kanye nohlobo lwe-tenon groove, olusetshenziswa kabanzi ngohlobo olubushelelezi, futhi oluthengekayo, olungabizi kakhulu.
2. Ukushisela izinqe:izingqimba zangaphakathi nezingaphandle ze-i-flangekufanele zishiselwe.Ivamise ukusetshenziselwa amapayipi anomfutho ophakathi nendawo nophezulu, kanti umfutho wepayipi uphakathi kuka-0.25 no-2.5MPa.Indawo yokubeka uphawu yokuxhumeka kwe-butt welding flange i-concave-convex, ukufakwa kuyinkimbinkimbi kakhulu, ngakho-ke izindleko zabasebenzi, indlela yokufaka kanye nezindleko zempahla ezisizayo ziphakeme kakhulu.
3. I-Socket Welding: ngokuvamile asetshenziselwa amapayipi anengcindezi encane noma elingana no-10.0mpa kanye nobubanzi obuncane obungaphansi noma obulingana no-40mm.
4. Umkhono oxekethile: ngokuvamile esetshenziselwa ingcindezi ayikho phezulu kodwa okuphakathi konakala kakhulu epayipini, ngakho lolu hlobo lwe-flange lunokumelana nokugqwala okuqinile, okubalulekile ikakhulukazi insimbi engagqwali.

Lolu hlobo lokuxhuma lusetshenziselwa ikakhulukazi ukuxhunywa kwepayipi lensimbi ecijile, ipayipi lensimbi yerabha, ipayipi lensimbi elingelona elensimbi kanye ne-valve ye-flange, njll., ukuxhumana kwemishini yenqubo kanye ne-flange nakho kuyasetshenziswa.i-flangeuxhumano.
Inqubo yokuxhuma i-Flange imi kanje: Ukuxhumeka kwe-Flange nepayipi kufanele kuhlangabezane nezidingo ezilandelayo:
1. Isikhungo sepayipi kanyei-flangekufanele ibe sezingeni elifanayo.
2. Indawo yokuvala yesikhungo sepayipi kanye ne-flange ingama-degree angama-90 aqondile.
3. Isikhundla sikai-flangeamabhawodi epayipini kufanele ahambisane.
