Cov yeeb nkab ncaj seam steel yog lub npe dav dav ntawm high-frequency ncaj seams, faus arc ncaj seams, ncaj vuam stitches, thiab pipeline ncaj seams. Lub high-frequency ncaj seam steel yeeb nkab siv cov nyhuv epidermis ntawm high-frequency tam sim no, thiaj li hais tias qhov kawg ntawm steel phaj tuaj yeem tsim kom muaj qhov kub thiab txias thiab sab nraud quab yuam hauv lub sijhawm luv luv hauv lub sijhawm luv luv. Squeezing, qhov no yog tiag tiag tsis-electrode thiab pheej yig hlau docking.
Nrog kub-dov coils li raw cov ntaub ntawv, phab ntsa thickness ntawm ERW high-frequency ncaj seam steel kav yuav tswj tau ntawm li ± 0.2 hli. Qhov kawg ntawm cov yeeb nkab steel txais yuav US APL tus qauv lossis GB / T9711.1 tus qauv, thiab cov yeeb nkab kawg txiav yog tsau. Nyob rau hauv xyoo tas los no, ntawm natural gas pipe network engineering thiab natural gas, ERW steel pipes tau dav siv los ua cov kav hlau tseem ceeb ntawm cov kav dej hauv nroog. Tam sim no, ERW high-frequency ncaj seam steel kav suav txog 60% ntawm lub ntiaj teb cov kav hlau.
Kev kho saum npoo ntawm cov kav dej ncaj seam steel yog ib qho tseem ceeb uas txiav txim siab lub neej ntawm cov kav dej siv los tiv thaiv corrosion. Nws yog qhov yuav tsum tau ua ua ntej seb puas muaj cov tshuaj tiv thaiv corrosive thiab cov kav hlau steel tuaj yeem ua ke ruaj khov. Cov kev tshawb fawb tau pom tias lub neej kev pab cuam ntawm anticorrosive txheej yog nyob ntawm seb hom txheej txheej, txheej txheej zoo, thiab kev tsim kho nyob rau hauv ib puag ncig, kev kho deg ntawm cov kav hlau ncaj nraim ntawm lub neej ntawm cov txheej txheem anticorrosive yog li 50%. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tshawb nrhiav thiab sau cov ntsiab lus ntawm txoj kev kho saum npoo ntawm cov kav hlau steel kom nruj raws li cov kev cai ntawm cov yeeb nkab steel nto anticorrosive txheej specifications.
1. Kev tu cov kav hlau ncaj nraim yog ntxuav nrog cov kuab tshuaj thiab emulsion rau saum npoo ntawm cov hlau kom tshem tawm cov roj, roj, plua plav, roj nplua nyeem, thiab cov organic zoo sib xws, tab sis nws tsis tuaj yeem tshem tawm oxide daim tawv nqaij, xeb ntawm cov hlau, vuam. , thiab lwm yam., tsuas yog siv tau los tiv thaiv corrosion ntau lawm Pab txhais tau tias.
2. Yog hais tias cov hlau nto yog ruaj khov rau cov hlau oxide av, nws cov xeb tshem tawm cov nyhuv tsis txaus siab, thiab nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom thauj tog rau nkoj ntawm kev tsim kho. Qhov ncaj seam steel yeeb nkab xeb tshem tawm cov cuab yeej tsuas yog siv cov hlau hlau txhuam thiab lwm yam cuab yeej los txhuam cov hlau nto. Kev tshem tawm xeb tuaj yeem ncav cuag qib SA2. Kev tshem tawm cov cuab yeej hluav taws xob tuaj yeem ncav cuag qib SA3. tos.
3. Cov pickles ntawm cov kav hlau ncaj yog feem ntau kho nrog cov tshuaj thiab electrolytic txoj kev. Nws tuaj yeem raug kho raws li kev kho dua tshiab tom qab sandblasting. Txawm hais tias cov tshuaj ntxuav tau tuaj yeem ua rau lub ntsej muag huv si thiab ntxhib, cov khoom sib tsoo yog qhov ntiav. Nws yog ib qho yooj yim ua rau muaj kuab paug rau ib puag ncig. Cov yeeb nkab anticorrosion tsuas tuaj yeem kho nrog tshuaj tua kab, uas tuaj yeem tshem tawm oxidation, xeb thiab cov txheej qub.
