Description
316 Welded Stainless Steel Tube ASTM A312 TP316 21.3mm-1219mm OD Industrial Pressure Pipe
Product Overview
Our 316 welded stainless steel tubes provide a cost-effective alternative to seamless pipe without compromising on quality. Manufactured per ASTM A312 TP316 specification, these tubes feature post-weld heat treatment and 100% NDT inspection for pressure-critical applications.

Key Features
  • Large Diameter Capability: Available in sizes up to 1219mm OD, filling the gap where seamless production is limited or uneconomical
  • Fully Tested Weld Seam: Every weld seam undergoes ultrasonic or radiographic inspection per ASTM standards
  • Cost-Effective Alternative: Welded construction reduces material cost by 15-30% compared to seamless for large diameters
  • Post-Weld Annealing: Heat treatment restores corrosion resistance at the weld zone
