ASTM A53 ERW steel pipe from TPMC is produced by high-frequency welding of steel strip, featuring a longitudinal weld seam, precise dimensions, and lightweight construction.
UL Listed and FM Approved, it provides reliable performance in water-based fire protection systems, including wet, dry, deluge, and preaction pipelines.
Additionally, our TPMC pipe excels in conveying steam, water, and air in industrial environments, while its excellent weldability supports general structural applications such as scaffolding, handrails, and framing.
