1. Ukushisela okuyisicaba:kuphela ukushisela ungqimba lwangaphandle, ngaphandle kokushisela ungqimba lwangaphakathi;Ngokujwayelekile esetshenziswa kumapayipi anengcindezi ephakathi nendawo, ingcindezi yepayipi ingaphansi kuka-0.25mpa.Kunezinhlobo ezintathu ze-sealing surfaceflat Welding flange, okuwuhlobo olubushelelezi, uhlobo lwe-concave kanye ne-convex kanye nohlobo lwe-tenon groove.Phakathi kwazo, uhlobo olubushelelezi lusetshenziswa kakhulu, futhi intengo iyathengeka futhi iyabiza.
2. Ukushisela izinqe:kokubili izingqimba zangaphakathi nezangaphandle ze-i-flangekufanele ashiselwe, ngokuvamile asetshenziswe emigqeni yomfutho ophakathi nendawo nophezulu, futhi ukucindezela okulinganiselwe kwepayipi kuphakathi kuka-0.25 ~ 2.5mpa.Indawo yokuvalwa kwe-welding flangeuxhumano luyi-concave futhi luyi-convex, futhi ukufakwa kuyinkimbinkimbi kakhulu, ngakho-ke izindleko zabasebenzi, indlela yokufaka kanye nezindleko zempahla eyisizayo ziphezulu uma kuqhathaniswa.

3. I-Socket Welding:ngokuvamile esetshenziselwa ukucindezela okulinganiselwe ingaphansi noma ilingana no-10.0MPa, ububanzi obujwayelekile bungaphansi noma bulingana no-40mm epayipini.
4. Umkhono oxegayo: Ivamise ukusetshenziswa epayipini elinengcindezi ephansi kodwa iphakathi nendawo ebolayo, ngakho lolu hlobo lwe-flange lunokumelana nokugqwala okuqinile, futhi impahla ngokuyinhloko iyinsimbi engagqwali.
Lolu hlobo lokuxhuma lusetshenziselwa ikakhulukazi ukuxhunywa kwepayipi lensimbi, i-bushing hose, ipayipi lensimbi engeyona eyensimbi kanyei-valve ye-flange, njll., kanye nokuxhumeka kwemishini yenqubo kanye ne-flange nakho kuxhunywe ne-flange.
