ASTM A213 vs ASTM A312: TP316L yeeb nkab
Tso lus
Thaum muas TP316L stainless hlau kav, ntau tus neeg yuav khoom tau txais cov lus hais raws li ASTM A213 TP316L thiab ASTM A312 TP316L. Txawm hais tias ob qho khoom siv tib yam 316L stainless hlau qib (UNS S31603), lawv tsis yog cov qauv sib hloov. Xaiv qhov kev qhia tsis raug tuaj yeem ua rau muaj teeb meem kev teeb tsa, kev tshuaj xyuas tsis tiav, cov nqi tsis tsim nyog, lossis qhov project qeeb.
Phau ntawv qhia no piav qhia txog qhov sib txawv ntawm ASTM A213 TP316L Tube thiab ASTM A312 TP316L Yeeb Nkab, pab EPC cov neeg ua haujlwm, cov chaw tsim hluav taws xob hloov hluav taws xob, refineries, thiab cov neeg yuav khoom ua qhov kev txiav txim siab yuav raug.
Dab tsi yog qhov txawv ntawm ASTM A213 thiab ASTM A312?
ASTM A213 npog seamless raj tsim los siv rau hauv boilers, superheaters, thiab tshav kub exchangers-tshwj xeeb seamless, nyias-walled hlab tsim rau siab- kub, siab - cov khoom siv hluav taws xob hloov hluav taws xob; Hauv qhov sib piv, ASTM A312 npog seamless, welded, thiab txias - ua haujlwm welded austenitic stainless hlau kav npaj rau cov txheej txheem piping thiab kev pabcuam corrosive.
Dab tsi yog qhovASTM A213 TP316L khoom?
ASTM A213 TP316L yog tus qauv tshwj xeeb rau seamless austenitic stainless hlau tubing npaj rau siab - kub thiab corrosive ib puag ncig, xws li boilers, superheaters, thiab tshav kub exchangers. Qhov "L" nyob rau hauv qib kev xaiv sawv cev rau "Low Carbon"; Cov ntsiab lus tsis tshua muaj cov pa roj carbon tsawg (qhov siab tshaj 0.035%) ua rau cov hlau tiv thaiv kev puas tsuaj, ua kom cov khoom tsis plam nws cov corrosion kuj. Tsis tas li ntawd, qhov kev txwv sab saud rau qhov ntsuas kub tsis tu ncua yog kwv yees li 870℃(1,598℃F).
Dab tsi yogASTM A312 TP 316Lkhoom?
ASTM A312 TP316L yog cov khoom siv tshwj xeeb rau seamless, welded, thiab txias hnyav - ua haujlwm austenitic stainless hlau kav. Lub npe "L" sawv cev rau "Low Carbon," uas qhia txog qhov muaj pes tsawg leeg uas tiv thaiv cov carbide nag lossis daus thaum lub sijhawm vuam, yog li tshem tawm qhov xav tau tom qab-weld annealing. Nrog rau qhov tsawg kawg nkaus tensile lub zog ntawm 485 MPa (70,000 psi) thiab qhov tsawg kawg nkaus yield zog ntawm 170 MPa (25,000 psi), qib no yog dav siv nyob rau hauv petrochemical, tshuaj ua, tshuaj, thiab marine industries.
ASTM A213 TP316L vs ASTM A312 TP316L Kev tsim khoom
ASTM A213: Tshwj xeeb seamless. Tubes yog extruded los yog kos los ntawm ib tug khoom billet yam tsis muaj welded pob qij txha.
ASTM A312: tuaj yeem ua seamless, welded, lossis txias hnyav - ua haujlwm. Yog tias welded, tsis muaj cov hlau muab tub lim ntxiv thaum lub sijhawm vuam.

High- ntim khoom hiav txwv zoo
Kev Tiv Thaiv Thaum Kawg: Txhua lub yeeb nkab haum nrog lub hau yas kawg (qhib lossis kaw hom) txhawm rau tiv thaiv kev sib kis sab hauv thiab kev puas tsuaj rau cov npoo kawg.
Kev Tiv Thaiv Qhov Nto: Cov kav dej tuaj yeem ua ib lub tes tsho hauv cov yeeb yaj kiab yas los yog ntim rau hauv cov duab hexagonal thiab qhwv hauv cov hnab woven kom tsis txhob khawb qhov chaw thaum lub sijhawm thauj khoom.
Ntoo Case Ntim: Plywood lossis khoom ntoo rooj plaub yog siv- tsim nyog rau LCL cov khoom xa tuaj lossis siab -cov kav dej A213- kom ntseeg tau tias tsis muaj deformation tshwm sim thaum caij tsheb npav.
Marking / Labeling: Txhua yeeb nkab bears meej inkjet cov cim (tus qauv, qib steel, specifications, cua sov tooj), thiab txheej ntim qhia txog cov khoom xa tuaj.
