Khoom Taw qhia

ASTM A928 tus qauv npog hluav taws xob fusion welded kav,ASTM A928 UNS S32750 EFW yeeb nkab yog super duplex alloy nrog zoo heev corrosion kuj. Cov ntsiab lus chromium siab nyob rau hauv cov hlau tso cai rau nws tiv taus ntau dua cov tshuaj chloride. Tsis zoo li qib 316 lossis 304, Super Duplex 2507 hluav taws xob welded kav muaj kev tiv thaiv corrosion zoo dua. Vim lawv cov kev siv kub kub, cov kav dej no tau nrov hauv cov qhov dej qaub thiab kev lag luam roj thiab roj.

ASTM A928 Standard npog tsib qib:

Kev ua haujlwm ntawm Chav Kawm 1 thiab 2 suav nrog ob qhov vuam, thiab qib 1 cov kav dej yuav tsum tau kuaj hluav taws xob.
Kev vuam ntawm A928 UNS S32750 EFW kav chav kawm 3 thiab 4 siv ib qho kev vuam thiab raug kuaj hluav taws xob.
Qib 5 yuav tsum muaj cov txheej txheem duplex weld nrog cov hlau muab tub lim, thiab tus qauv yuav tsum tau kuaj xyuas qhov chaw radiography ntawm A928 S32750 Class 5 electrofusion welded yeeb nkab.
