DN100 114.3mm ERW Steel Pipe ASTM A53 For Water Pipeline

Huayang DN100 114.3 mm ASTM A53 Grade B ERW steel pipes are manufactured using advanced high-frequency electric resistance welding technology, providing uniform wall thickness, excellent roundness, and high weld integrity. ASTM A53 Grade B is a widely accepted carbon steel specification with a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa, offering excellent weldability, ductility, and pressure resistance. The 114.3 mm outside diameter is commonly selected for municipal water supply lines, pumping stations, industrial cooling water systems, and utility pipeline networks. Huayang can also provide external FBE, 3PE, or hot-dip galvanized coatings and internal epoxy lining to improve corrosion resistance and extend service life. Every pipe undergoes hydrostatic testing, ultrasonic weld inspection, dimensional verification, and mechanical property testing to ensure full compliance with ASTM A53 requirements.
