ASTM A795 seamless steel pipe from TPMC is manufactured by piercing solid billets using the advanced PQF process, ensuring a uniform, seamless structure with exceptional strength and reliability.
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.
