API 5L carbon steel qib B seamless yeeb nkab muaj kev ua haujlwm kub zoo, zoo ductility thiab weldability. Nws yog cov kav dej dav dav rau kev thauj mus los ntawm cov roj thiab cov kav dej. Kuj tseem hu ua L245 yeeb nkab, xa mus rau ISO 3183, nrog qhov tsawg kawg nkaus tawm lub zog ntawm 245 MPa (355, 000 Psi).
API 5L B qib steel yeeb nkab yog tsuas yog siv rau cov roj thiab roj kev thauj mus los xws li cov kav dej thiab cov kav dej ntuj. Nws cov khoom siv zoo heev thiab kev tiv thaiv corrosion ua rau cov yeeb nkab steel no muaj ntau yam kev thov kev cia siab hauv kev thauj mus los ntawm cov roj thiab roj.
API 5L B qib steel yeeb nkab tuaj yeem xa hauv kub dov, tswj dov, kev kho cua sov (normalizing, tempering, quenching + tempering, thiab lwm yam) xeev. Cov kev xa khoom sib txawv no tuaj yeem hloov kho raws li cov neeg siv khoom xav tau thiab cov kev xav tau ntawm engineering.
API 5L Gr B yeeb nkab tuaj yeem raug cais raws li cov qauv xws li kev tsim cov kav dej, cov lus qhia tshwj xeeb, qhov chaw tiav thiab cov yeeb nkab kawg hom. API 5L Qib B seamless yeeb nkab tuaj yeem tsim tau txog 24 ntiv tes, LSAW lossis LSAW yeeb nkab tuaj yeem tsim tau txog 24 ntiv tes thiab siab dua, thiab hluav taws xob tsis kam welded yeeb nkab lossis ERW tuaj yeem tsim tau txog 20 ntiv tes) cov lus qhia qib kawg siv yeeb nkab.
