Our Stainless Steel 304L & 316L Pipes are precision-engineered for superior corrosion resistance and durability across industrial, chemical, and architectural applications. Available in seamless, ERW (Electric Resistance Welded), and EFW (Electric Fusion Welded) variants, these pipes meet stringent international standards including ASTM A312, ASTM A269, and EN 10216-5.
Ideal for food processing, pharmaceuticals, chemical transport, and construction, these pipes offer excellent weldability, formability, and hygienic properties.
Premium Materials:
304L (UNS S30403): Low-carbon version of 304, ideal for welding and high-temperature applications (up to 870°C).
316L (UNS S31603): Molybdenum-enhanced for superior chloride resistance (PREN ≥25), perfect for marine/coastal environments.
Manufacturing Versatility:
Seamless Pipes: ASTM A312, ideal for high-pressure systems.
ERW Pipes: Cost-effective, smooth interior for fluid transport.
EFW Pipes: Thicker walls for structural/industrial use.
Certified Quality:
Compliant with ASTM A312/A269 (US), EN 10216-5 (EU), JIS G3459 (Japan), and GB/T 14976 (China).
Third-party tested (PMI, hydrostatic, UT/RT available).
