Product Details

ASTM A795 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 features tight dimensional tolerances to ensure excellent compatibility with precision fittings and grooved connections.
Available in SCH10 for cost-effective branch lines and SCH40 for mains, risers, or high-durability needs, our TPMC pipe provides reliable performance in wet, dry, deluge, and preaction fire protection systems.
