Yini okufanele ngiyinake lapho ngisebenzisa i-neck butt welding flange?

Zonke insimbi ngeintamo isinqe welding flangeizinto ezifakwayo zizosabela nge-oxygen yasemkhathini, kwakheka ifilimu ye-oxide ngaphezulu. Umkhiqizo kufanele ufakwe ngokulandela imiyalelo, ukuze kuqinisekiswe ukusebenza okuvamile komkhiqizo esikhathini esizayo. Namuhla, kunamamodeli amaningi omkhiqizo. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, imikhiqizo ethuthukisiwe iya ngokuya ihambisana nezidingo zabantu. Ikakhulukazi, imikhiqizo yenkampani ithuthuka njalo ekusebenzeni.

Uma iintamo isinqe welding flangeihlanganiswe ngohlobo olufanayo lwe-electrode yensimbi engenasici ye-chromium (G202, G207), kufanele ishiswe kuqala ibe ngaphezu kuka-300 ngemva kokushisela, futhi ipholiswe kancane kancane cishe ku-700. Ukufakwa kwe-weld flange kufanele kusetshenziswe.

Yini okufanele ngiyinake lapho ngisebenzisa i-neck butt welding flange?

1. I-Flangeukufakwa nge-neck butt welding kunokumelana nokugqwala okuhle nokumelana ne-oxidation ku-welding rod kanye ne-butt welding flange, esetshenziswa kabanzi kumanyolo wamakhemikhali, imboni yamakhemikhali, i-petroleum kanye nokukhiqizwa kwemishini yezokwelapha.

2. Ngesikhathi sokushiswa kwe-flangeukufakwa nge-neck butt welding, ama-carbides ancishiswa ukushisa okuphindaphindiwe, okuholela ekwehleni kwezakhiwo zemishini kanye nokumelana nokugqwala.

3. Ukwenza lukhuni i-American flange ene-neck butt welding flange fittings inkulu ngemva kokushisela futhi kulula ukuqhekeka. Uma uhlobo olufanayo lwe-electrode yensimbi engagqwali ye-chromium (G202, G207) kufanele ibe ngaphezu kokushisisa kwangaphambili okungu-300 kanye nokwelashwa kokupholisa okuhamba kancane okungu-700 ngemva kokushisela. Uma i-weldment ingakwazi ukuphathwa ngokushisa ngemva kokushisela, i-electrode ene-neck weld flange fittings (A107, A207) kufanele ikhethwe.

Ukuzalwa kwemikhiqizo empilweni yomuntu kulethe ukunethezeka okuningi, imikhiqizo ayishintshi, kodwa ngokuthuthukiswa kwesayensi nobuchwepheshe emisha. Ngakho-ke, kubaluleke kakhulu ukukhetha umkhiqizo ofanele ukuze uzuze wena.

Ngenxa yokumelana nokugqwala okuhle kwensimbi engagqwali, amalungu esakhiwo angagcinwa unomphela ngobuqotho bomklamo wobunjiniyela. Ama-flange ensimbi engenasici e-Chrome nawo ahlanganisa amandla emishini ne-ductility ephezulu futhi kulula ukuwenza ukuze ahlangabezane nezidingo zabadwebi bezakhiwo nabaklami bezakhiwo.
