CovASTM A312 Yeeb Nkabmuaj alloying ntsiab xws li chromium, npib tsib xee, tooj liab, molybdenum, thiab lwm yam, uas muab lawv zoo heev kam rau ua thiab tsis kam mus rau corrosive thiab oxidative media thoob plaws kev ntxhov siab vim teeb. Cov qib ntau yam npog seamless, ntau yam txias ua haujlwm welded austenitic stainless hlau thiab ncaj weld yeeb nkab modules. CovASTM A312 Teem caij 40 Yeeb Nkabyog tsim los siv rau hauv qhov kub thiab txias thiab feem ntau pom nyob rau hauv nruab nrab siab tshuab. Lub sch 40 yeeb nkab yog ib lub sij hawm uas cov yeeb nkab no muaj nyob rau hauv kev lag luam. CovASME SA12 Tubeyog cov qib siab ntawm cov raj xa dej uas tsim los rau kev ua kom siab siab thiab ntsuas kub. Cov modules no muaj lub zog zoo thiab tsis yooj yim khoov lossis distort nyob rau txhua qhov xwm txheej.
CovASTM A312 Seamless Yeeb Nkabnyob rau hauv qib no yog cov khoom siv muaj zog uas yog tsim los ntawm cov txheej txheem extrusion. Ntawm no cov hlau kub kub tau dhau los ntawm cov hlau extruded, tso cai rau lawv ua kom zoo li qhov tseeb qhov ntev. Tsim tsis muaj welds lossis seams, lubASME SA 312 Seamless Yeeb Nkabyog siv nyob rau hauv high-temperature setups. Cov kav dej no tau txhim kho lub zog thiab muaj peev xwm ua tau zoo heev. Lawv muaj 20% siab dua-tuav lub peev xwm piv rau cov kav dej welded hauv qib no. CovASTM A312 Cold Draw Seamless Pipestau ua tiav ntxiv tom qab cov txheej txheem kub dov. Raws li cov kav dej tau khiav dhau los tuag, lawv qhov kev tiv thaiv thiab qhov chaw tiav tau txhim kho, muab cov khoom zoo rau lawv.A312 welded yeeb nkabmuab cov kev daws teeb meem zoo tshaj tus nqi piv rau cov kav dej seamless. Cov kav dej no yog tsim los ntawm cov ntawv yob los yog ib lub strips thiab vuam lawv nyob rau hauv qhov chaw raws li cov txheej txheem vuam txheej txheem. Peb lub tuam txhab khaws cia cov kav dej ntawm cov duab sib txawv thiab qhov ntau thiab tsawg tso cai rau koj xaiv cov khoom zoo.
