    Khoom Qhia Qhia

    Khoom Ntawv

    Spiral submerged arc welded pipe is an important part of water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. Nws cov vagatility thiab kev ntseeg tau tau ua nws ib ntawm nees nkaum cov khoom lag luam tseem ceeb tsim hauv peb lub tebchaws, ua rau muaj kev lag luam tseem ceeb thiab cuam tshuam rau ntau yam kev lag luam.

    SSAW steel yeeb nkabYog kev ua si rau kev thauj khoom ntawm cov kua thiab yog qhov zoo tshaj plaws rau cov dej thiab cov nqus dej. Nws cov kev tsim kho ruaj khov ua rau nws zoo tagnrho rau kom ua kom muaj kua hloov tau zoo thiab txhim khu kev qha. Ib qho ntxiv, nws tseem haum rau kev thauj roj tsheb xws li roj cua, chav dej, thiab roj av roj av. Nws lub zog tensile muaj zog thiab corrosion tiv thaiv kom muaj kev nyab xeeb thiab ua kom muaj txiaj ntsig roj thiab ua tau raws li qhov yuav tsum tau ua kom cov pa roj.
