Supply & Demand

Hot Dip Galvanized Seamless Steel Pipe is produced via hot piercing and cold drawing to create seamless tubing free of weld seams, followed by hot-dip galvanizing. Its seamless structure avoids welding defects including weld cracks and leakage. Equipped with internal and external hot-dip galvanized anti-corrosion layers, the pipe delivers excellent pressure resistance and rust protection. Manufactured in accordance with GB/T8163, ASTM A53, ASTM A106 and EN10216 standards, it is extensively adopted in high-pressure fluid conveyance, petroleum, chemical engineering, fire protection projects, high-pressure water supply, underground anti-corrosion pipelines and mechanical structural applications.

Hot Dip Galvanized (HDG) Steel Pipe is manufactured by straight seam welding of carbon steel strips, then treated with hot-dip galvanizing process. The whole pipe is immersed in high-temperature molten zinc to form a tight anti-corrosion zinc coating on both inner and outer walls. Our galvanized pipes strictly implement GB/T3091, EN10255, ASTM A53, BS1387 standards, fixed length commonly 6 meters, available with threaded ends or plain ends. Widely applied in construction scaffolding, fire protection piping, water supply & drainage, agricultural greenhouse frameworks, municipal engineering, gas delivery and steel structure projects.
