API 5L Qib B Pipe Specifications

API 5L-B (L245) pipeline steel ua raws li API SPEC 5L tus qauv thiab yog qib ntawm cov kav dej steel, sib npaug rau L245 tus qauv. "L" sawv cev rau thawj tsab ntawv ntawm "Kab," thiab "245" qhia qhov tsawg kawg nkaus qhov kev tawm dag zog ntawm cov hlau, qhia hauv megapascals (MPa). Tsis tas li ntawd, L245 steel phaj kuj ua raws li GB / T21237 tus qauv.
