Xav txog kev teem rau hlau Stainless Flange

Chuangyi hlau khoom Co., Ltd | Updated: Jun 27, 2016

1, kom tsis txhob muaj qhov muag corrosion vim yog lub flange tebchaw cua sov, vuam tamsis no tsis loj heev, tsis muaj li 20% dua cov pa roj carbon steel electrodes, arc yuav tsis tau mus ntev lawm, ceev cov cua txias, nqaim hlaws yog tsim nyog.

2, tus electrode yuav tsum khaws tseg cia qhuav, kua qaub-Titania yam yuav tsum tau 150 ℃ qhuav 1 teev, ib hydrogen uas tsis muaj yam yuav tsum tau 200-250 ℃ qhuav 1 teev (tsis ua kom qhuav, los yos tawv nqaij nws cracking spalling), cov roj thiab lwm cov av ntawd tsis pub electrode so, thiaj li tsis mus nyhuv uas ua rau kom cov txheej ntawm weld thiab weld zoo.

3, hlau stainless flange vuam, ua rau cov cua kub precipitated carbides, kuj muaj corrosion thiab txhua yam khoom.

4, chrome stainless hlau flange tom qab vuam thiab cov qhov hauv koj cov flange American txheem no loj, kom tawg yooj yim. Yog siv tib hom chromium hlau stainless electrode (G202, G207) vuam, yuav tsum tau tshaj 300 tawm ℃ Preheat thiab ncej weld qeeb txias txog li 700 c. Yog tus weld tshav kub kho tom qab vuam yog tsis tau, koj yuav tsum siv hlau stainless flange vuam qws (A107, A207).

5, hlau stainless flange, thiaj li ua hauj corrosion thiab weldability nrog ua nyiaj stability ntsiab Ti, Nb, Mo, zoo weldability ntawm CR hlau stainless flange. Siv tib hom chromium hlau stainless flanged electrode (G302, G307), yuav tsum muaj ntau tshaj 200 ℃ Preheat thiab ncej weld 800 ℃ tempered. Yog hais tias cov kev kho mob kub weld yog tsis tau, koj yuav tsum siv hlau stainless flange vuam qws (A107, A207).
