A269 316L Stainless Hlau Pipe Description
A{{0}}L stainless hlau yeeb nkab, tseem hu ua 00Cr17Ni14Mo2 stainless hlau yeeb nkab, hais txog ultra-low carbon steel nrog qib 00Cr17Ni14Mo2, uas muaj kev tiv thaiv zoo dua. intergranular corrosion tshaj 0Cr17Ni12Mo2. Nws yog feem ntau siv rau hauv kev tsim cov khoom siv hauv kev lag luam tshuaj, chiv, thiab hluavtaws fiber ntau, xws li ntim, kav dej, thiab cov khoom siv. Txhawm rau txhim kho cov yam ntxwv ntawm 316L stainless hlau yeeb nkab, cov txheej txheem tshwj xeeb yog ua haujlwm rau kev ua haujlwm sab hauv thiab sab nrauv ntawm cov kav dej, suav nrog pickling thiab passivation (AP), mechanical polishing (MP), ci annealing (BA), thiab electrolytic polishing. (EP) kev kho mob.

A269 316L SS Tube
316L Stainless Hlau Yeeb Nkab Kev Kho Mob:
- AP (Acid Pickling)
Kev tiv thaiv corrosion ntawm stainless hlau feem ntau tshwm sim los ntawm cov tshuaj tiv thaiv ntawm chromium cov ntsiab lus uas muaj nyob rau hauv nws thiab oxygen, uas tsim ib tug ntom oxide zaj duab xis ntawm nws nto. Lub hom phiaj ntawm cov txheej txheem acid pickling yog ua kom cov tshuaj tiv thaiv no ntxov ntxov, yog li txhim kho corrosion kuj ntawm 316L stainless hlau kav. Thaum lub sij hawm cov kua qaub pickling txheej txheem, roj stains, av, thiab lwm yam khoom adhering rau saum npoo ntawm 316L stainless hlau yeeb nkab raug tshem tawm kom huv si. Sab hauv thiab sab nrauv ntawm cov yeeb nkab yog qhov ntxhib, ua rau lawv yooj yim mus rau tsub zuj zuj ntawm tshem tawm impurities thiab residues.
- BA (Bright Annealing)
Polishing log los yog siv rau kev sib tsoo thiab polishing nto ntawm 316L stainless hlau kav nrog abrasives nyob rau hauv polishing agents, yog li ua tiav ib tug du thiab ci polished nyhuv ntawm cov kav dej. Qhov ci ntsa iab ntawm qhov saum npoo yog nyob ntawm hom kev siv cov txheej txheem. Tsis tas li ntawd, thaum kho tshuab polishing txhim kho qhov zoo nkauj, nws tuaj yeem txo qhov kev tiv thaiv corrosion. Yog li ntawd, thaum siv nyob rau hauv corrosive ib puag ncig, yuav tsum tau kho passivation ntxiv, thiab residues ntawm polishing cov ntaub ntawv feem ntau pom nyob rau saum npoo ntawm 316L stainless hlau kav.
- MP (Mechanical Polishing)
Thaum lub sij hawm tsim cov txheej txheem ntawm 316L stainless hlau kav, lub lubricating roj nplej yuav deform vim kev tsim khoom. Txhawm rau txo cov roj seem nyob hauv 316L stainless hlau kav, thaum lub sij hawm annealing txheej txheem, kub kub yog siv nrog argon roj raws li cov cua hauv lub cub tawg. Cov roj argon ua ke nrog cov pa roj carbon thiab oxygen rau ntawm qhov chaw ntawm 316L stainless hlau kav kom kub hnyiab, ntxiv ntxuav qhov chaw thiab ua tiav qhov ci tiav. Cov txheej txheem no, hu ua ci ntsa iab annealing, suav nrog cua sov nrog cov pa roj ntshiab argon thiab cua txias kom ci ntsa iab. Thaum txoj kev no ua kom huv si yam tsis muaj kev kis kab mob txawv teb chaws rau ntawm qhov chaw ntawm 316L stainless hlau kav, qhov ci ntsa iab yuav tshwm sim hazy piv rau lwm txoj kev polishing xws li tshuab, tshuaj, lossis electrolytic. Txawm li cas los xij, qhov ua tau zoo kuj yog nyob ntawm cov ntsiab lus argon thiab tus naj npawb ntawm cov cua sov.
- EP (Electro Polishing)
Electro polishing siv txoj kev kho anodic raws li cov txheej txheem electrochemical. Los ntawm kev kho qhov voltage, tam sim no, acid muaj pes tsawg leeg, thiab polishing lub sij hawm kom tsim nyog, txoj kev no tsis tsuas yog ua tiav ib tug kaj, du, thiab huv si saum npoo, tab sis kuj txhim khu lub corrosion kuj ntawm nto. Yog li ntawd, nws yog ib txoj hauv kev zoo rau kev ua tiav qhov ci ntsa iab. Tau kawg, nws cov nqi thiab thev naus laus zis kuj tseem yuav nce ntxiv.
