API 5L Kab Yeeb Nkab: Daim Ntawv Qhia Kom Zoo rau Cov Tshuaj Muaj Zog thiab Kev Ua Haujlwm

Taw qhia:

 

API 5L yog ib qho kev qhia tshwj xeeb uas tsim los ntawm American Petroleum Institute (API) rau seamless thiab welded steel kav siv hauv kev thauj mus los hauv kev lag luam roj av thiab roj av.Womic Steel, lub tuam txhab ua lag luam ntawm API 5L kab kav dej, muaj ntau yam khoom lag luam uas ua tau raws ntau qib thiab cov lus qhia tshwj xeeb.Kab lus no muab cov ncauj lus kom ntxaws sib piv ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov qauv ntsuas sib txawv rau qib API 5L, ob qho tib si PSL1 thiab PSL2 thoob plaws peb hom kav: ERW (Electric Resistance Welded), LSAW (Longitudinal Submerged Arc Welded), thiab SMLS (Tsis muaj).
