Khoom Taw Qhia
ASTM A691 EFW Yeeb Nkab yog ib hom welded steel yeeb nkab, uas yog hais txog cov yeeb nkab steel nrog seams rau ntawm qhov chaw uas yog welded tom qab khoov thiab deforming steel strips los yog steel daim hlau mus rau hauv round lossis square duab. ASTM A691 EFW Yeeb Nkab siv cov txheej txheem hluav taws xob fusion vuam, uas yog txheej txheem uas cov hlau sib xyaw ua ke los ntawm cua sov cov hlau ntawm ib lossis ob peb cov khoom siv hluav taws xob thiab cov khoom ua haujlwm.
Qhov zoo
ASTM A691 EFW Yeeb Nkab siv steel phaj lossis sawb hlau ua billet. Nrog rau txoj kev loj hlob sai ntawm cov khoom zoo zoo nruam dov ntau lawm thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm welds tseem txhim kho, ntau yam thiab specifications ntawm welded steel kav yog nce. Welded steel kav muaj tus nqi qis dua thiab ua haujlwm ntau dua li cov kav dej seamless.

Nyob rau hauv cov txheej txheem ntawm cov roj thiab cov pa xa mus rau pipeline anticorrosion siv, ncaj seam steel yeeb nkab nto kev kho mob yog ib qho tseem ceeb ntawm kev txiav txim lub neej kev pab cuam ntawm lub raj xa dej corrosion, nws yog ib tug khoom ua ke ntawm anti-corrosion txheej thiab ncaj seam steel yeeb nkab yuav ua tau. muab. Kev tshawb fawb kev tshawb fawb ntawm cov chaw tshwj xeeb, lub neej ntawm txheej yog nyob ntawm qhov zoo ntawm txheej txheej, txheej txheej thiab kev tsim kho ib puag ncig, xws li ncaj seam steel yeeb nkab nto kho cov teebmeem ntawm txheej txheej lub neej suav txog li 50%, yog li ntawd, yuav tsum nruj nruj. Raws li cov kev qhia tshwj xeeb ntawm cov txheej txheej ntawm qhov chaw ncaj seam steel yeeb nkab yuav tsum tau ua, txuas ntxiv txhim kho qhov ncaj seam steel yeeb nkab nto kho.
Ncaj seam steel yeeb nkab ntxiv rau txoj kev embroider:
1, Cov tshuaj tsuag derusting
Txau derusting yog tsav los ntawm high-power motor jet high-speed rotating hniav, steel txhaj, steel grit, hlau seem, minerals thiab lwm yam abrasive nyob rau hauv lub cev muaj zog lub zog nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam ntawm ncaj seam steel yeeb nkab nto txau, tsis tsuas muaj peev xwm tshem tawm oxide, xeb thiab av, thiab ncaj seam steel yeeb nkab nyob rau hauv qhov kev txiav txim ntawm abrasive quab yuam thiab kev sib txhuam, kuj tuaj yeem ua tiav qhov xav tau kev ntxhib los mos.
2, ntxuav
Siv cov kuab tshuaj, emulsion steel nto ntxuav, kom tshem tawm cov roj, roj, av, lubricants, thiab cov organic teeb meem zoo sib xws, tab sis nws tsis tuaj yeem tshem tawm xeb, nplai, xws li vuam flux ntawm cov hlau, yog li tsuas yog pab txhais tau tias hauv kev tiv thaiv. tsoom fwv txoj hauj lwm.
3, cuab yeej, tu
Lub ntsiab USES steel hlau txhuam cov cuab yeej rau steel nto xws li kev sib tsoo, tuaj yeem tshem tawm cov nplais xoob, xeb, slag, thiab lwm yam. Cov cuab yeej tes tuaj yeem ua tiav qib Sa2, cov cuab yeej siv hluav taws xob tu tuaj yeem ncav cuag qib Sa3, yog cov hlau oxide adhered rau ntawm qhov chaw steel, cov cuab yeej tu cov nyhuv tsis zoo tagnrho, thauj tog rau nkoj qauv qhov tob ntawm kev siv tshuaj tiv thaiv corrosion.
