ASTM A312 SS316LN Steel Pipe Chaw tsim tshuaj paus. Tiv tauj peb kom tau txais kev tsocai dawb thiab qauv!
316 LN ibyog austenitic stainless hlau tsim los ntawm optimizing cov ntsiab lus nitrogen nyob rau hauv lub hauv paus ntawm 316L stainless hlau. Nws cov txiaj ntsig tseem ceeb yog kev ua haujlwm zoo corrosion, siab zog, thiab kev ua haujlwm zoo. Qhov sib ntxiv ntawm cov ntsiab lus nitrogen tsis yog tsuas yog txhim kho cov khoom siv zog, tab sis kuj tsis ua rau nws lub zog thiab corrosion kuj stability. HT PIPE yog SS 316Ln yeeb nkab xa khoom nrog 15+ kev xa tawm.Tiv tauj pebkom paub ntau ntxiv thiab quotes dawb!
ss317ln khoom Chav ntsuas kub txhua yam khoom
Yield zog:Ntau dua lossis sib npaug rau 275MPa, nce txog 34% piv rau 316L (Ntau dua lossis sib npaug rau 205MPa).
Tensile zog:Ntau dua lossis sib npaug ntawm 585MPa, elongation ntawm kev tawg (δ ₅): Ntau dua lossis sib npaug li 40%.
Hardness:Tsawg dua los yog sib npaug rau 220, nruab nrab Brinell hardness.
Impact zog:Ntau dua lossis sib npaug li 60J.
Kev ua haujlwm kub kub:Nyob rau hauv thaj tsam ntawm 200-600 degree, lub zog tseem ruaj khov, thiab thermal conductivity thiab linear expansion coefficient yog qis dua li cov pa roj carbon zoo tib yam.
Tsawg kub ua haujlwm:Qhov tsawg kawg nkaus ua haujlwm kub tuaj yeem ncav cuag -270 degree, ze rau cov kua nitrogen kub, thiab tseem tsis muaj kev pheej hmoo ntawm kev tawg ntawm qhov kub no.
| Element | ASTM A312 TP316LN Limits (Wt.%) |

stainless hlau 316ln kev ua haujlwm ntev
Fatigue zog:Nyob rau hauv cyclic loading, lub qaug zog txwv yog siab tshaj 316L, tshwj xeeb tshaj yog nyob rau hauv high kub los yog corrosive ib puag ncig, qhov twg lub neej qaug zog yog zoo dua.
Creep Performance:Nyob rau hauv qhov kub thiab txias ntev - lub sij hawm thauj khoom ntawm 400-600 degree, lub creep deformation yog me me, thiab creep fracture zog yog siab dua li ntawm 316L.
Cov ntsiab lus tseem ceeb rau kev siv thiab tu
316lb steel yeeb nkab Kev teeb tsa thiab sib dhos
Thaum lub sij hawm lub installation txheej txheem, tsis txhob khawb qhov nto passivation zaj duab xis. Plasma txiav lossis laser txiav yuav tsum zoo dua rau kev txiav, thiab daim tawv nqaij oxide, burrs, thiab slag ntawm cov npoo yuav tsum tau muab tshem tawm tam sim tom qab txiav.
Thaum nyob rau hauv kev sib cuag nrog cov hlau sib txawv xws li carbon steel thiab qis - alloy steel, rwb thaiv tsev gaskets yuav tsum tau siv rau kev sib cais, los yog los tiv thaiv -corrosion coatings yuav tsum tau siv rau qhov chaw tiv tauj los tiv thaiv galvanic corrosion.
Stainless hlau bolts ntawm tib yam khoom los yog sib npaug corrosion kuj yuav tsum tau xaiv rau fastening bolts kom tsis txhob ntsia liaj qhov rooj tsis ua hauj lwm los ntawm corrosion ntawm dissimilar hlau.
Vuam los yog flange kev twb kev txuas yog nyiam rau cov kav dej txuas. Tom qab vuam, vuam slag thiab spatter rau saum npoo ntawm vuam seam yuav tsum tau muab tshem tawm, thiab kev kho mob passivation yuav tsum tau nqa tawm dua yog tias tsim nyog.
ss316ln steel yeeb nkab Tu thiab tu
Kev tu txhua hnub tuaj yeem siv cov dej huv lossis cov tshuaj ntxuav tes kom tshem tawm cov plua plav saum npoo av, roj stains, thiab lwm yam kuab paug. Tom qab yaug, so qhuav nrog ib daim ntaub huv kom lub ntsej muag qhuav.
Tsis txhob siv cov tshuaj ntxuav corrosive xws li tshuaj dawb chlorine, muaj zog acids (hydrochloric acid, nitric acid), thiab cov hauv paus muaj zog (sodium hydroxide) los tiv thaiv kev puas tsuaj rau cov yeeb yaj kiab passivation. Yog tias qhov chaw muaj kab mob zoo li no, tam sim ntawd yaug nrog dej kom ntau.
Tom qab siv sijhawm ntev -, yog tias muaj xeb me ntsis los yog stains ntawm qhov chaw, ib tus neeg saib xyuas tshwj xeeb stainless hlau tuaj yeem siv los so nws, tom qab ntawd yaug nrog dej huv thiab so qhuav kom rov zoo dua ntawm cov yeeb yaj kiab passivation.
Rau cov kav xa dej nyob rau hauv kev ua haujlwm hnyav xws li thaj chaw marine thiab siab - qhov kub thiab txias corrosive ib puag ncig, nws raug nquahu kom ua qhov kev tshuaj xyuas saum npoo thiab kev saib xyuas txhua 6-12 lub hlis kom sai li sai tau cov ntsiab lus corrosion hauv zos.
