304 thiab 316 Stainless Hlau Chev Ua tiav thiab ua tiav
Kev ua tiav ntawm stainless hlau kauj tsis yog tshuaj pleev ib ce xwb. Nws qhia txog txoj hauv kev thiab cuam tshuam rau kev tsim khoom, kev huv, kev xav, thiab qee zaum kev coj cwj pwm hauv kev pabcuam. Raws li Euro Inox,1Dyog ib qho kub dov, annealed, descaled tiav siv rau ntawm daim ntawv tuab thiab phaj qhov zoo li theem nrab.2Dyog ib qho txias dov, kub kho, pickled matt tiav.2Byog tsim los ntawm 2D nrog lub teeb kawg dov dhau, muab cov xim grey tiav cov neeg yuav khoom feem ntau nug rau hauv kev lag luam thiab kev tsim khoom.2Ryog txoj kev ci ntsa iab annealed, muab qhov ua kom pom tseeb uas yooj yim dua los ntxuav.
Rau cov khoom siv coil, qhov no tseem ceeb hauv ob qho xwm txheej. Thawj yog thaum cov txheej txheem qis qis suav nrog polishing, txhuam hniav, lossis kho kom zoo nkauj; Nyob rau hauv tas li ntawd, pib nrog txoj cai zeb tiav txuag ntxiv rework. Qhov thib ob yog thaum kawg siv yog kev tu cev -sensitive lossis zoo li-sensitive.

304 vs 316 Stainless hlau kauj
Qhov txawv ntawm304 stainless hlau kaujthiab316 stainless hlau kaujtsis yog chemistry xwb. Nws yuav pom thaum lub kauj yog txiav, tsim, welded, thiab raug rau cov kev pab cuam tiag tiag. Qib 304 tseem yog tus qauv xaiv rau kev tsim khoom siv dav vim nws muaj kev tiv thaiv corrosion zoo, weldability zoo, thiab ruaj khov ua haujlwm. Qib 316 raug xaiv thaum cov tshuaj chloride- bearing noo noo, tshuaj ntxuav cov ntaub ntawv, los yog aggressive water exposure ua rau cov kev pab cuam ib puag ncig tsis zam txim.
Ib qho piv txwv zoo yog qhov sib txawv ntawm lub vaj huam sib luag khoom noj khoom haus sab hauv tsev thiab cov ntug dej hiav txwv lossis tshuaj lom neeg - txheej txheem fabrication. A304 stainless hlau kaujfeem ntau txaus rau cov khoom siv hauv chav ua noj, cov khoom siv vaj huam sib luag, thiab cov vaj tsev nyob sab hauv. Thaum cov khoom raug tsim los rau hauv cov ntim tshuaj, marine- cov khoom siv uas nyob ib sab, kev tsim sab nrauv ze ze rau qhov raug ntsev, lossis cov khoom siv uas raug tshuaj chloride ntxuav,316 stainless hlau kaujfeem ntau tsim nyog rau kev txhim kho vim hais tias ib puag ncig, tsis tsuas yog cov khoom siv tus nqi, feem ntau tsav tsis ua haujlwm.
Uas tau hais tias, 316 tsis yog lus teb rau txhua qhov kev pabcuam corrosive. Cov kev taw qhia pej xeem corrosion kuj tseem sau tseg tias cov qauv austenitic qib xws li304Lthiab316Ltseem tuaj yeem nkag siab rauchloride-induced stress corrosion cracking at high temperature. Yog li yog tias qhov kev pabcuam yog ob qho tib si chloride- nplua nuj thiab kub, qhov kev txiav txim siab qib yuav tsum tau txav mus dhau tus qauv 304/316 kauj thiab mus rau qhov siab dua - alloy lossis duplex txoj kev.
304 thiab 316 Stainless Hlau Chev Daim Ntawv Thov
304 Stainless hlau kauj
304 stainless hlau kaujfeem ntau yog siv rautso tsheb hlau luam, cov khoom vaj tse, cov txheej txheem npog, kev lag luam hauv chav ua noj, dab dej, cov khoom siv vaj huam sib luag, thiab cov ntawv welded dav -cov khoom siv hlauqhov twg huv si sib sau, ruaj khov vuam, thiab dav corrosion kuj yuav tsum tau. Nws yog qhov kev xaiv tswv yim rau qhov chaw uas yuav yogtxiav, khoov, dov, stamped, los yog maj mam polishedthaum lub sij hawm fabrication, tshwj xeeb tshaj yog thaum qhov kev pab cuam ib puag ncig yog nyob rau hauv tsev los yog tsuas yog me ntsis corrosive.
Nws kuj yog siv dav rauzaub mov-cov khoom sib cuag, cov khoom siv sab hauv tsev, lub teeb- ntsuas qhov chaw tsim khoom, thiab kev tsim vaj tsevmuab tso tseg los ntawm kev raug ntsev ncaj qha. Hauv cov ntawv thov no, tus nqi tseem ceeb ntawm 304 yog tias nws muaj qhov sib npaug zoo ntawmnto tiav, fabrication stability, thiab tswj tus nqiyam tsis hloov mus rau qib siab dua - alloy.
316 Stainless hlau kauj
316 stainless hlau kaujyog tsim nyog rau qhov chaw raugchloride- bearing washdown, tshuaj tiv tauj, huab cua ntug hiav txwv dej, dej- kev kho mob, lim cov ntxaij vab tshaus, tso tsheb hlau luam, thiab marine- nyob ib sab fabrication. Nws feem ntau xaiv thaum qhov ua tiav yuav tsum nyob hauv ntub dej rau lub sijhawm ntev, pom cov tshuaj ntxuav ntau dua, lossis ua haujlwm nyob rau hauv qhov chaw uas txiav npoo, qhov chaw vuam, thiab cov crevices feem ntau yuav ntsib kev pheej hmoo corrosion.
Qhov no ua rau 316 qhov pib zoo dua rau kev tsim khoom siv hauvCov txheej txheem tshuaj lom neeg, kev teeb tsa ntawm ntug dej hiav txwv, dej- tuav tswj, thiab corrosion{1}} kev pabcuam sab nraum zoov. Qhov twg ib puag ncig yog hnyav dua li cov khoom siv sab hauv tsev, qhov ntxiv alloying nyob rau hauv 316 pab muab qhov zoo tshaj plaws corrosion margin tshaj 304.Rau tej yaam num uas xav tau los ze zog saib ntawm lubtsev neeg qib 316, saib316L, 316Ti, thiab 316H stainless hlau.
Vim li cas thiaj xaiv Octal Pipe
Rau304 thiab 316 stainless hlau kaujkev txiav txim, qhov txiaj ntsig tiag tiag tsis yog tsuas yog muab cov qib nws tus kheej xwb, tab sis tswj kev txiav txim ua ntej nws mus txog ntau lawm. Octal Pipe tuaj yeem pab kho cov khoom ntawm cov ntsiab lus uas feem ntau tsim teeb meem hauv qab:qib, tiav, thickness, dav, slit dav, tiv thaiv nto, thiab muab daim ntawvxws limaster coil, slit coil, los yog txiav - mus rau - daim ntawv ntev. Qhov no ua rau cov ntaub ntawv yooj yim dua los ua ke nrog yob txoj kev, vaj huam sib luag fabrication, raj ua, los yog cov ntawv dav dav -kev ua hlau.
Qhov no tseem ceeb tshwj xeeb tshaj yog thaum ib qhov project suav nrog ntau tshaj ib txoj kev, xws li304 stainless hlau kaujrau general fabrication,316 stainless hlau kaujrau ntau corrosive kev pab cuam, thiabstainless hlau coil striprau nqaim - dav ua. Kev tswj xyuas kom meej ntawm cov ntsiab lus no yuav pab txo qis cov teeb meem xws li kev xaiv ua tiav tsis raug, qhov dav qhov tsis zoo, kev tiv thaiv nto tsis sib xws, lossis kev hloov kho kev cob qhia ntxiv tom qab tuaj txog.
Octal Yeeb Nkab kuj txhawb nqa qhov kev txiav txim los ntawm kev tso tawm sab, qhov twg ntau coil tej yaam num raug ncua los ntawm kev ua lag luam tsis tiav thiab kev sib raug zoo. Ib pob khoom kom meej dua txhais tau tias cov khoom tuaj yeem raug tshuaj xyuas raws li qhov xav tautxheem, tiav, qhov ntev, packing method, thiab traceability cov ntaub ntawvua ntej xa khoom xa tuaj, ua kom tau txais, khaws cia, thiab kev ua haujlwm qis qis kom tswj tau yooj yim dua.
