It is suitable for low-pressure fluid transportation (≤2.3MPa), building fire protection pipe network, agricultural irrigation and municipal water supply and drainage. The nominal size covers 1/8"~26" (outer diameter 10.3-660mm), supports threaded/welded/grooved connection, is cost-effective and compatible with international engineering standards, and is a general-purpose medium and low-pressure galvanized pipe in North America and around the world.

ASTM A500 galvanized pipe is a galvanized steel pipe for cold-bent structures in accordance with American standards, with a yield strength of 250-450MPa, a tensile strength of ≥415MPa, a galvanized layer of ≥61μm, and a salt spray corrosion resistance of over 500 hours. It is suitable for building steel frames, photovoltaic brackets, and heavy fences, supports welding/bolt connections, and has a cross-sectional stiffness that is 30% higher than that of ordinary pipes, making it the first choice for high-stress scenarios.

ASTM A106 galvanized seamless pipe is a high-temperature and high-pressure carbon steel seamless pipe of American standard. It is formed with a ≥65μm anti-corrosion layer through hot-dip galvanizing process, with a tensile strength of ≥415MPa, temperature resistance of -29℃ to 427℃, and pressure resistance of 13.8MPa (Grade C). Its weld-free structure eliminates leakage risks and is suitable for harsh working conditions such as petrochemical steam/power plant main steam/supercritical boilers. The coating is metallurgically bonded with the substrate, and the salt spray corrosion rate is <0.003mm/year. The service life is 3 times longer than that of ordinary pipes, and it is the safety cornerstone of high-risk energy transmission systems.
