Tso lus
ASTM A312 TP321 seamless steel kav peb muab yog tsim los ntawm extruding kub steel billets, ua rau lub seamless raj yam tsis muaj pob qij txha los yog welds. Los ntawm ci ntsa iab annealing, cov kav dej ua tiav qhov chaw du thiab meej qhov ntev, ua rau lawv tsim nyog rau kev siv hauv petrochemical, siab - cov cuab yeej kub, thiab kev thauj mus los hauv xov xwm corrosive.
Cov kav dej no ua raws li cov qauv xws li ASME SA-312 thiab ASTM A312. EN 1.4541 (sib npaug rau TP321) cov kav dej tuaj yeem hloov kho ntau yam duab thiab ntau thiab tsawg raws li cov neeg siv khoom xav tau. Cov kav dej feem ntau yog siv rau hauv cov pob qij txha txuas ntxiv, cov khoom siv hluav taws xob sib hloov, cov khoom siv rau cov khoom siv hluav taws xob, cov khoom siv dav hlau dav hlau, cov tshuab raj, thiab cov ntawv siv zoo sib xws.
