ABS A yog lub zog dav dav hlau phaj ntawv pov thawj los ntawm American Bureau of Shipping (ABS) rau kev tsim nkoj, paub txog nws lub zog siab, ua haujlwm ntev, thiab tiv thaiv corrosion. Nws feem ntau yog siv los tsim cov hulls thiab lwm yam khoom siv ntawm cov nkoj thiab offshore platforms. Cov khoom yog tus cwj pwm los ntawm qhov tsawg kawg nkaus lub zog ntawm 235 MPa thiab lub zog tensile ntawm 400 thiab 520 MPa.
Cov khoom tseem ceeb thiab cov yam ntxwv
Khoom siv: Lub siab -lub zog, qis- carbon structural steel phaj.
Daim ntawv pov thawj: Certified los ntawm American Bureau of Shipping (ABS) rau marine thiab shipbuilding daim ntaub ntawv.
Kev siv thawj zaug: Siv dav hauv kev tsim kho cov nkoj xws li nkoj, nkoj, thiab cov chaw ua haujlwm sab nraud.
