Product Description
ASTM A269 TP316L Stainless Steel Seamless Coil Tube
Corrosion-resistant seamless austenitic stainless steel tubing for high-temperature service applications, manufactured to ASTM A269 standards and supplied in coiled form for continuous long-length installations.
Product Overview
This seamless austenitic stainless steel tubing meets ASTM A269 standards for general service applications. The coiled form enables continuous runs without joints, while the TP316L grade designation indicates:
- TP: Denotes "Tube Pipe" for tubular products
- 316L: Low-carbon variant alloyed with Molybdenum for enhanced corrosion resistance
Key Advantages
- Superior Corrosion Resistance: Molybdenum content provides enhanced resistance to pitting and crevice corrosion in chloride environments
- Excellent Weldability & Fabricability: Low carbon content minimizes carbide precipitation during welding
- High & Low Temperature Service: Suitable for cryogenic to elevated temperature applications
- Seamless Integrity: Uniform structure without weld lines for superior strength and reliability
Standard Specifications & Manufacturing
Governing Standard: ASTM A269/A269M for Seamless and Welded Austenitic Stainless Steel Tubing
Manufacturing Process: Seamless production through piercing and extrusion with cold drawing for precise dimensions
Heat Treatment: Solution annealed condition (≥1040°C) with rapid cooling to optimize corrosion resistance
Testing & Inspection: Non-destructive electric testing, hydrostatic testing, and additional mechanical tests per standard requirements
