Product Detail

SPECIFICATION

Khoom cim npe

Siv rau -60C tej yam yuav tsum tau muaj ib puag ncig, feem ntau yog siv rau shipbuilding, pipeline, siab nkoj vuam.

Dab tsi yog characieristics?

●Hlau hmoov hom submerged arc vuam hlau ntawm 480MPa qib siab zog hlau yog welded nrog GXL-121 flux. Lub arc combustion yog ruaj khov, lub slag tshem tawm yog ib qho yooj yim, thiab vuam dhau txoj kev yog zoo nkauj.

●Lub vuam hlau muaj cov khoom siv zoo heev, cov ntsiab lus tsis tshua muaj P thiab S, thiab kev ua haujlwm kub tsis zoo.
