Cov khoom siv stainless hlau yog siv los tsim ntau yam khoom. Cov kav dej yog ib qho ntawm lawv. Lawv muab faib ua subcategories. ASTM A312 Stainless Hlau Yeeb Nkab yog ib qib zoo li no uas hnyav hnyav ua haujlwm welded stainless hlau yeeb nkab. Nws yog tsim los siv rau hauv qhov kub thiab txias thiab cov kev pabcuam siab uas feem ntau pom corrosion. Lawv yog tsim los ntawm welded, seamless, los yog coldworked daim ntawv. ASTM A312 Yeeb Nkab muaj ib txoj kab uas hla ntawm ⅛ ntiv tes mus rau 30 ntiv tes loj. Lub thickness ntawm cov kav dej no txawv ntawm lub sij hawm 10s mus rau lub sij hawm 80. Filler hlau tsis tas yuav tsum tau ntxiv rau cov txheej txheem vuam.

A312 cov khoom siv yeeb nkab yog dawb los ntawm cov hlau tsis huv thiab oxide scaling. Nyob rau hauv rooj plaub hais tias cov yeeb nkab yog ci annealed ces tsis muaj qhov yuav tsum tau rau nto finishing, blasting, los yog pickling. Txawm li cas los xij, ntawm cov neeg siv khoom thov, cov kav dej no tuaj yeem ua dhau los. ASME SA312 tuaj yeem ua rau tus kheej quenched lossis txias sai hauv dej tom qab kev kho cua sov. Cov hluav taws xob fusion welded kav dej tsis tshua muaj kev cuam tshuam rau hauv cheeb tsam corrosion thaum piv rau lwm cov kav dej. Cov pa roj carbon tsawg ntawm cov kav dej no ua rau lawv yooj yim rau kev tsim thiab vuam. ASTM A312Mis muaj nyob rau hauv 1.2 hli mus rau 2 hli thickness. Cov yeeb nkab muaj nyob rau hauv qhov ntau thiab tsawg ntawm 3 meters, 6 meters, thiab 10 meters. Cov kav dej txhuam thiab satin tiav yog siv hauv khw thiab ntau qhov chaw vim lawv qhov zoo nkauj.
ASTM A312 Seamless Stainless Hlau Yeeb Nkab yog thawb lossis rub los tsim cov khoom siv raw khoom siv los tsim cov kav dej seamless. Cov khoom muab los ntawm peb tau dhau los ntawm ntau yam kev ntsuam xyuas xws li hydrostatic test, flattening test, straightness, thiab deg zoo kuaj thiab lwm yam. ASTM A312 Tubing muaj cov txiaj ntsig zoo thiab lub zog tensile. Lawv kuj tso siab rau siab. Lawv muaj qhov melting point ntawm 1400 ° C thiab qhov ceev ntawm 8.0 g / cm3. Cov kav dej no tuaj yeem tiv taus cov neeg kho tshuab siab thiab tau hais tias rov siv tau dua. 312 cov kav dej muab los ntawm peb tau ua raws li cov qauv thoob ntiaj teb thiab tau txais kev saib xyuas zoo tshaj plaws.
