Kev tshuaj xyuas thiab tswj ntawm API 5L Txuj rauSubmerged Arc Welded Steel Yeeb Nkab
Submerged Arc Welded Steel KavTau siv dav hauv cov roj thiab cov roj nkev thauj mus los, thiab lawv cov neeg Asmeskas yog ua raws li cov qauv API 5 tus qauv ntawm American roj av lub koom haum. Tus qauv qhia meej txog kev tsim khoom, tshuaj xyuas thiab kev tswj kom zoo ntawm submerged arc welded steel kav hauv kev nyab xeeb los xyuas kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov kav dej. API 5L tus qauv muab faib rau ob qib steel rau ob qib: PSL1 thiab PSL1 thiab PSL1 yog tsim nyog rau kev siv dav dav, thaum tsim nyog rau kev siv nruj heev.
Hauv kev tsim khoom,Submerged Arc Welded Steel Kavyog ua los ntawm cov hlau zoo tais lossis cov phaj loj, thiab cov hlau geometric qhov tseeb thiab vuam zoo los ntawm kev tsim cov txheej txheem xws li uoe thiab jcoe. Nyob rau hauv cov txheej txheem vuam, muab ob sab-sided submerged arc vuam technology yog saws tau pom los ntawm on-line nruam ultrasonic yoj kom ntseeg tau tias kev ywj pheej. Ib qho ntxiv, cov kav hlau hlau yuav tsum tau mus kuaj qhov zoo li qub, suav nrog x-ray kuaj thiab ultrasonic kuaj, txhawm rau txheeb xyuas qhov zoo ntawm Welds.
API 5L tus qauv tseem qhia txog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv mechanies ntawm cov kav hlau. Cov tshuaj lom neeg tshuaj lom neeg ntawm cov yeeb nkab steel yuav tsum nruj me ntsis tswj kom ntseeg tau tias nws cov kev nruj thiab corrosion tsis kam. Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, cov kav hlau yuav tsum tau raws li cov kev xav tau tshwj xeeb ntawm cov txiaj ntsig lub zog thiab lub zog tensile kom haum rau cov chaw sib txawv engineing. Tsis tas li ntawd, API 5L tus qauv tseem npog cov ncauj lus kom ntxaws, kom ntseeg tau tias muaj kev nyab xeeb thiab kev ua haujlwm ruaj khov ntawm cov chaw muaj ntau yam.
Nyob rau hauv ib lo lus, API 5L tus qauv muab cov kev coj ua kom muaj kev tsim khoom rau kev tsim khoom thiab kev siv ntawmSubmerged Arc Welded Steel Kav, thiab ua kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm cov raj xa hluav taws xob hauv cov chaw muaj ntau yam.
