ASTM A312 yog cov yeeb nkab steel yeeb nkab khoom tus qauv. Nws yog tsuas yog siv los tsim seamless thiab welded yeeb nkab steel kav. Nws txoj kev siv npog roj av, tshuaj lom neeg, hluav taws xob fais fab, metallurgy thiab hydraulic yeeb nkab industries. Nws cov yam ntxwv tseem ceeb yog cov yeeb nkab yuav tsum muaj lub zog zoo compressive thiab zoo tensile lub zog, thiab muaj corrosion kuj zoo. Thaum tshav kub kub tsis kam thiab sealing kuj yog ib qho ntawm cov cim tseem ceeb.
ASTM A312 tus qauv muab faib ua peb theem: TP304L, TP316L thiab TP321L. TP304L yog npib tsib xee-chromium stainless hlau nrog zoo corrosion kuj thiab kub tsis kam. Qhov kub siab tshaj plaws tuaj yeem ncav cuag 800 degree, qhov tsawg kawg nkaus kub tuaj yeem ncav cuag -320 degree, thiab nws lub zog compressive tuaj yeem ncav cuag 200 megabytes ib square centimeter. Pa. TP316L yog nickel-molybdenum alloy steel nrog ntau dua corrosion kuj. Nws lub zog compressive tuaj yeem ncav cuag 220 MPa ib square centimeter, qhov kub siab tshaj plaws tuaj yeem ncav cuag 850 degree, thiab qhov ntsuas kub tsawg tshaj plaws tuaj yeem ncav cuag -320 degree . Thaum kawg, TP321L yog npib tsib xee-chromium-titanium alloy hlau nrog qhov siab tshaj plaws corrosion kuj. Nws lub zog compressive tuaj yeem ncav cuag 230 MPa ib square centimeter, qhov kub siab tshaj plaws tuaj yeem ncav cuag 900 degree, thiab qhov ntsuas kub tsawg tshaj plaws tuaj yeem ncav cuag -320 degree C.
Qhov loj ntawm ASTM A312 tus qauv yeeb nkab feem ntau yog kho raws li cov neeg siv khoom xav tau. Lub thickness ntawm cov yeeb nkab kuj muaj nyob rau hauv kev xaiv sib txawv, los ntawm 2.11mm mus rau 50.8mm. Txoj kab uas hla ntawm cov yeeb nkab yog los ntawm 1/8 "mus rau 4", thaum lub puab txoj kab uas hla yog txiav txim los ntawm cov neeg siv khoom xav tau. Nug kom txiav txim siab.
Muaj peb txoj kev kho deg rau ASTM A312 tus qauv kav: kev kho cua sov, seamless, thiab electroforming. Kev kho cua sov yog muab cov yeeb nkab rau kev kho cua sov kom nws qhov chaw du thiab muaj kev tiv thaiv corrosion zoo dua.

FAQ
Q. Koj puas tuaj yeem xa cov qauv?
A. Tseeb, peb tuaj yeem xa cov qauv mus rau thoob plaws lub ntiaj teb. Tab sis cov neeg siv khoom yuav tsum them tus nqi xa khoom.
Q. Koj lub sijhawm ua haujlwm yog dab tsi?
A. Peb muaj Tshuag txaus txhua hnub, yog li rau qhov ntau thiab tsawg, peb tsuas xav tau txog 7 hnub Tshuag. Yog tias koj xav tau xaj tshwj xeeb loj, peb xav tau cov khoom tshiab tsim lub sijhawm.
Q. Kuv tuaj yeem tau txais cov lus hais los ntawm koj li cas?
A. Koj tuaj yeem tso peb cov lus, thiab peb yuav teb txhua cov lus hauv lub sijhawm. Los yog peb yuav tham onine los ntawm kev lag luam manaqer. Thiab koj tuaj yeem pom peb cov ntaub ntawv tiv toj ntawm nplooj ntawv tiv tauj.
