ASTM A53 yeeb nkab yog cov yeeb nkab steel uas ua raws li Asmeskas tus qauv ASTM thiab feem ntau yog siv los thauj cov pa roj, kua thiab lwm yam dej.
ASTM A53 cov kav dej tau muab faib ua ob hom: seamless steel kav thiab hluav taws xob welded steel kav. Lawv muaj ntau qhov ntau thiab tsawg thiab tuab thiab tuaj yeem kho raws li cov neeg siv khoom xav tau. Cov yeeb nkab muaj cov khoom siv zoo thiab kev tiv thaiv corrosion thiab yog dav siv nyob rau hauv industrial thiab mechanical fields, nrog rau cov dej, cua sov thiab cua txias systems nyob rau hauv kev tsim kho kev lag luam.
Cov qib siab ntawm ASTM A53 cov kav dej yog Class A thiab Class B, uas sib haum rau ntau qhov sib txawv. Ntawm lawv, Chav A muaj qhov siab ntawm 150 psi rau 300 psi (10 bar txog 20 bar), thaum Chav B muaj qhov siab ntawm 300 psi rau 400 psi (20 bar rau 28 bar).
