Seamless stainless steel pipes manufactured by hot extrusion or cold rolling processes, with austenitic stainless steels such as 304/316L as the base material, undergo multiple cold rolling and bright annealing treatments to achieve a uniform metallographic structure throughout the entire wall thickness. The product complies with the ASTM A312 standard, featuring zero risk of weld defects, higher pressure-bearing capacity and excellent medium purity. It is a core component of high-pressure and corrosive fluid conveying systems.
Galvalume Steel can be regarded as the "technological achievement" in the field of metal protection. Through the hot-dip galvanizing process, 55% aluminum and 45% zinc are perfectly fused to form a dense alloy coating, achieving dual effects of physical protection and electrochemical protection. Its corrosion resistance is four times that of ordinary galvanized steel, and it easily exceeds the 1,500-hour mark in the salt spray test. Even under the rigorous 90° b…
