Nrog rau kev loj hlob sai ntawm kev lag luam hluav taws xob hauv tsev, daim ntawv thov ntawmstainless hlau kavkuj nce zuj zus. Nyob rau hauv cov txheej txheem ntawm kev siv tshuaj tiv thaiv corrosion ntawm cov roj thiab cov kav dej, muaj 304 stainless hlau capillaries, uas yog cov kav dej siab. Kev kho saum npoo ntawm cov kav hlau stainless yog ib qho tseem ceeb uas txiav txim siab lub neej kev pab cuam ntawm cov kav dej los tiv thaiv corrosion, thiab nws tseem yog ib qho tseem ceeb ua ntej rau kev sib xyaw ua ke ntawm cov txheej txheem tiv thaiv corrosion thiab cov yeeb nkab stainless hlau. Ntxiv nrog rau hom txheej txheej, txheej txheej zoo thiab kev tsim kho ib puag ncig, lub neej ntawm cov txheej txheem tiv thaiv corrosion nyob ntawm qhov zoo ntawm kev kho deg ntawm cov yeeb nkab steel hlau, uas suav txog li ib nrab ntawm lub neej. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua raws li cov kev cai ntawm cov txheej txheem tiv thaiv corrosion rau saum npoo ntawmstainless hlau kavthiab txuas ntxiv txhim kho cov txheej txheem kho saum npoo ntawm cov kav dej stainless hlau.
Tam sim no, txoj kev kho saum npoo ntawm cov kav hlau tsis muaj steel feem ntau yog tu, tshem tawm xeb, pickling, thiab lwm yam. Cov txheej txheem no tau qhia hauv qab no.
Ntxuav
Siv cov kuab tshuaj thiab emulsions los ntxuav cov hlau tsis huv tuaj yeem tshem tawm cov roj, roj, plua plav, lubricants thiab cov organic zoo sib xws, tab sis txoj kev no tsis tuaj yeem tshem tawm xeb, nplai, vuam flux, thiab lwm yam. ib tug pab txhais tau tias nyob rau hauv anti-corrosion ntau lawm.
Cov cuab yeej xeb tshem tawm
Feem ntau, cov cuab yeej xws li hlau txhuam yog siv los txhuam qhov saum npoo ntawm cov hlau tsis huv, uas tuaj yeem tshem tawm xoob lossis tsa cov nplai, xeb, vuam slag, thiab lwm yam. Cov cuab yeej tshem tawm xeb tuaj yeem ncav cuag qib Sa2, thiab cov cuab yeej hluav taws xob xeb tshem tawm tuaj yeem ncav cuag Sa3 qib. . Yog hais tias qhov saum npoo ntawm stainless hlau yog ruaj khov rau cov nplai ntawm cov hlau oxide, cov cuab yeej xeb tshem tawm tsis zoo thiab tsis tuaj yeem ncav cuag cov qauv thauj tog rau nkoj qhov tob uas yuav tsum tau ua los tiv thaiv corrosion.
Pickling
Feem ntau muaj ob txoj hauv kev rau pickling: tshuaj thiab electrolytic. Stainless hlau pipeline los tiv thaiv corrosion tsuas yog siv cov tshuaj pickling, uas tuaj yeem tshem tawm nplai, xeb, thiab txheej txheej qub. Qee lub sij hawm txoj kev no kuj tseem siv tau los ua kev kho dua tshiab tom qab sandblasting xeb tshem tawm. Txawm hais tias kev siv tshuaj tua kab mob tuaj yeem ua rau lub ntsej muag ncav cuag qee qhov kev huv thiab roughness, nws cov qauv thauj tog rau nkoj yog qhov ntiav thiab yooj yim rau paug ib puag ncig.
Tua blasting
Kev txhaj tshuaj blasting yog ib txoj hauv kev ntawm kev tshem tawm xeb. Lub tshuab hluav taws xob muaj zog tsav lub blasting hniav kom tig ntawm kev kub ceev, kom cov abrasives xws li steel xuab zeb, steel tua, xaim ntu, thiab cov ntxhia pob zeb tau tawg rau saum npoo ntawm cov yeeb nkab steel nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam. Nws tuaj yeem tsis tsuas yog tshem tawm xeb, oxides thiab av, tab sis kuj ua tiav qhov xav tau kev ntxhib los mos nyob rau hauv qhov kev cuam tshuam hnyav thiab kev sib txhuam ntawm cov abrasive.
Tom qab blasting xeb tshem tawm, nws tuaj yeem tsis tsuas yog nthuav tawm cov nyhuv adsorption ntawm qhov chaw ntawm cov yeeb nkab stainless hlau, tab sis kuj tseem txhim kho cov neeg kho tshuab adhesion ntawm txheej los tiv thaiv corrosion thiab cov yeeb nkab nto. Yog li ntawd, txhaj tshuaj blasting xeb tshem tawm yog ib qho zoo tagnrho xeb tshem tawm txoj kev rau pipeline corrosion tiv thaiv. Feem ntau hais lus, txhaj tshuaj blasting xeb tshem tawm feem ntau yog siv rau kev kho cov yeeb nkab sab hauv, thiab kev txhaj tshuaj blasting xeb tshem tawm tsuas yog siv rau sab nrauv kho cov yeeb nkab. Ntau qhov teeb meem yuav tsum tau them sai sai rau thaum siv tshuaj tua blasting xeb tshem tawm.
