Kev kho thiab polishing txheej txheem rau Stainless hlau Flanges
Loj stainless hlau flanges tuaj yeem raug xeb nyob rau hauv ib puag ncig zoo tib yam, feem ntau yog vim muaj cov hlau dawb ntawm txhua qhov chaw, uas tuaj yeem ua rau corrosion ntawm stainless hlau. Nws yog ib qho tseem ceeb kom tshem tawm cov impurities. Cov khoom xoob zoo li hmoov tuaj yeem raug tshem tawm nrog rau plua plav. Qee qhov hais tuaj yeem nkag mus tob thiab xav tau kev kho mob los daws cov kab mob hlau.
Ntxiv nrog rau cov plua plav, muaj ntau qhov chaw ntawm cov hlau tsis huv, nrog rau kev ntxuav nrog cov pa roj carbon hlau tsis tu ncua, siv cov xuab zeb, iav hlaws, lossis lwm yam abrasives rau kev tua blasting, uas yav tas los siv rau cov pa roj carbon ntau, cov hlau tsis tshua muaj hlau, los yog cam khwb cia hlau Cheebtsam. Tag nrho cov kev ua ub no yuav ua kom paub cov kab mob hlau tsis zoo rau hauv cov flanges stainless hlau thiab cov cuab yeej nyob ze ntawm cov khoom uas tsis yog cov hlau tsis muaj hlau hais thaum kho thiab sib tsoo.
Txoj kev tshem tawm xeb rau Flanges: Ib txoj hauv kev rau kev tshem tawm xeb yog raus lub flange hauv hydrochloric acid. Lub hauv paus ntsiab lus yog los txo cov xeb, tab sis txoj kev no muaj qee qhov kev pheej hmoo, vim hydrochloric acid yog cov khoom corrosive uas tsim kev puas tsuaj rau tib neeg. Thaum lub sijhawm ua haujlwm, kev ceev faj yog qhov tseem ceeb kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij thiab ua haujlwm nrog cov tshuaj alkaline es tsis txhob sib cuag nrog tes.
Kev tshuaj xyuas tom qab kev tsim khoom tuaj yeem pab tiv thaiv thiab kuaj pom muaj cov hlau dawb. ASTM tus qauv A380 qhia txog cov txheej txheem rau kev kuaj corrosion ntawm stainless hlau nto hlau lossis hlau hais. Txoj kev sim no yuav tsum tau siv thaum muaj kev ywj pheej los ntawm hlau. Yog tias cov txiaj ntsig tau txaus siab, qhov saum npoo yuav tsum tau muab yaug nrog dej distilled huv lossis nitric acid kom txog thaum cov xim xiav sib sib zog nqus raug tshem tawm tag nrho. Raws li tus qauv A380, yog tias cov xeb tsis tuaj yeem raug tshem tawm tag nrho siv cov tshuaj tiv thaiv xeb, nws tsis pom zoo rau cov chaw uas tuaj yeem cuam tshuam ncaj qha nrog cov khoom siv los ntawm tib neeg. Ib qho kev sim yooj yim yog kom nthuav tawm cov flange hauv dej rau 12-24 teev los xyuas seb puas xeb. Nws yog ib qho kev sim siab thiab siv sijhawm ntev. Cov no yog cov kev tshuaj ntsuam xyuas thiab tsis yog kev ntxuav. Yog tias pom hlau, nws yuav xav tau tshuaj lom neeg thiab electrochemical tu kom daws tau nws.
Nyob rau hauv cov txheej txheem polishing ntawm stainless hlau flanges, ib co dub oxide nplai los yog ANSI flanges nquag tshwm sim nyob rau saum npoo ntawm stainless hlau flanges, cuam tshuam rau lawv daim ntawv thov nqi. Daim ntawv thov ntawm ntau yam kev kho mob tom qab, nrog rau cov tshuab polishing, tshuaj polishing, thiab electrochemical polishing, yog tsim nyog los txhim kho lawv cov nqi. Cov txheej txheem hauv qab no raug pom zoo kom tau txais txiaj ntsig zoo dua:
Chemical Degreasing → Rinsing → Pickling → Rinsing → Chemical Polishing → Rinsing → Electropolishing → Rinsing → Passivation → Rinsing → Drying → Inspection.
Stainless hlau flange gaskets yuav muab faib ua mos gaskets thiab hard gaskets. Cov gaskets mos feem ntau yog siv rau cua sov, roj, thiab nruab nrab-rau-siab-siab industrial pipelines. Yog tias tsis muaj cov kev cai tshwj xeeb rau gasket tuab, cov kev qhia dav dav yog raws li hauv qab no: 1.6mm rau flanges nrog lub cheeb me dua 125mm, 2.4mm rau flanges loj dua 125mm tab sis me dua 500mm, thiab 3.2mm rau flanges loj dua 500mm. High-temperature, high-pressure chemical kev lag luam pipelines feem ntau siv hard gaskets, uas yog metallic gaskets.
SINO SPECIAL METAL muab ntau hom thiab cov ntaub ntawv ntawm cov yeeb nkab fittings, flanges, thiab cov kav dej. Peb yog cov chaw muag khoom ntseeg siab, thiab peb txais tos cov lus nug thiab kev yuav khoom.
