API 5L PSL1 THIAB PSL2 Kab Kavyog tshwj xeeb steel tubes tsim ua raws li Asmeskas Petroleum lub koom haum App, feem ntau siv rau kev thauj khoom ntev ntawm cov roj, nkawv roj, thiab dej. Lawv cov khoom lag luam muaj ntau yamseamless thiab welded steel kav, nrog kev tsim qauv xaus nrog raudawb xaus, xov xaus, thiab tswb xausCov. Cov Qauv Txuas Koom Tes NrogVuam, Coupling, thiab Tswb & Spigot Jointions.
Cov khoom siv feem ntau siv rau cov kav dej no npog steel qib kawm los ntawmL245, L360 txog X70 seriesCov. Lawv muaj nyob rau hauv ib tugTxheej ntawm txoj kab uas ntau li 60-630 hlithiabPhab Ntsa Thickness Tshwj Xeeb Los Ntawm 1.53-40 HliCov. Ntau Lawm Siv Sivmicro -} alloying Kev Kho Mob Cov Txheej Txheem, nrog siab dua -} qib cov khoom lag luam ua tiav kev ua tau zoo los ntawm kev kho cov roj carbon sib npaug thiab kev kho kom zoo kub.Annealing cov txheej txheem, suav nrogtag nrho annealing, spheroiding annealing, thiab kev nyuaj siab pab txhawb kev ua haujlwm, yog ua haujlwm kom tshem tawm cov kev ntxhov siab uas muaj kev ntxhov siab thiab ruaj khov cov qauv khoom.Kev kho temperingtuaj yeem txo cov quenleness thiab txhim kho cov khoom siv neeg txhua yam. Nrog kev nce qib hauv vuam siv thev naus laus zis, loj-}}} dia welded kav dej tau ua rau lawv tus nqi ntawm seamless kav yog qhov tsawg.
