Xov Xwm - API 5L Kab Yeeb: Ib Phau Ntawv Qhia Txog Tshuaj Tshuaj Lom Neeg thiab Kev Ua Tau Zoo

Taw qhia:

API 5L yog tus qauv qauv tau tsim los ntawm Asmeskas Petroleum lub koom haum (API) rau seamless thiab welded steel kav siv nyob rau hauv cov roj av thiab ntuj muaj kev lag luam. Puav hlau Steel, ib tug ua cov chaw tsim khoom ntawm API 5L Kab Kav, muaj ntau cov khoom lag luam uas tau raws qib ntau yam thiab cov ncauj lus tshwj xeeb. Cov ntawv sau no muab cov ncauj lus piav qhia cov ncauj lus kom ntxaws, thiab cov qauv ntsuas duab rau hauv lub sijhawm API 5, lsaw (Longitudinal sub welderged arc welded), thiab smls (seamless).

Ntau lawm muaj peev xwm thiab ntau yam:
