ASTM A335 Thick Wall Steel Tubing Cold Drawn With Great Oxidation Resistance
Alloy steel pipes are mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , by hot rolling (extrusion, expansion) or cold rolling (drawing).
