API 5L X70 kab seamless steel yeeb nkab

API 5L X70 yeeb nkab yog cov khoom siv qib siab zoo hauv API 5L tus qauv specifications. Kuj hu ua L485 yeeb nkab, raws li nws lub zog tawm los
Yam tsawg kawg nkaus hauv 485 Mpa (70,300 psi). API 5L X70 npog hom kev tsim khoom hauv seamless thiab welded (ERW, SAW) hom, ob qho tib si siv
rau roj thiab roj kis.

API X70 carbon steel kab yeeb nkab tuaj yeem txhais tau tias yog cov yeeb nkab steel nrog cov ntsiab lus siab carbon thiab alloying compound. API 5L X 70 carbon steel seamless yeeb nkab Ntxiv nrog rau cov lej ntawm lwm cov ntsiab lus xws li sulfur, phosphorus, thiab lwm yam, nws cov alloy muaj cov ntsiab lus siab ntawm manganese thiab silicon. Qhov sib ntxiv ntawm tag nrho cov ntsiab lus no pab txhim kho cov khoom siv ntawm X70 carbon steel yeeb nkab.

Qhov no tuaj yeem pom los ntawm lub zog qis qis (485 MPa) ntawm API 5L X70 Class B LSAW raj. Nws kuj muaj lub zog tensile yam tsawg kawg nkaus ntawm 635 MPa. Qhov saum npoo ntawm API 5L X70 SCH 40 DSAW raj yog kho nyob rau hauv ntau hom, xws li dub, anticorrosive roj, kub-dip galvanized los yog txias-galvanized. Raws li kev siv tshwj xeeb ntawm X70 PSL2 kauv raj, peb tuaj yeem pom zoo kho qhov zoo tshaj plaws rau peb cov neeg siv khoom. Piv txwv li, galvanized txheej ntawm X70 PSL1 qib kav qhia tau zoo heev corrosion kuj.
