ASTM A269, A249, A213 Stainless Steel Tubes For Heat Exchangers in Stock

GNEE offers ASTM A269, A249, and A213 stainless steel tubing for heat exchangers, all in stock. Made from high-quality, corrosion-resistant stainless steel (A269: TP304/304L, A249: TP304/316L, A213: TP304/316L/321), these tubings are available in seamless or welded constructions in strict compliance with ASTM standards. They offer high thermal conductivity, excellent high-temperature oxidation resistance (short-term exposure temperatures up to 900°C), and corrosion resistance in steam, water, and chemical environments. They also feature high dimensional accuracy (OD tolerance ±0.05 mm, wall thickness tolerance ±0.03 mm) and a surface quality of Ra ≤ 0.8μm, making them suitable for clean fluid applications.

 

GNEE stocks standard sizes from 12.7-114.3 mm OD and 0.8-3.0 mm wall thickness in both standard and custom lengths, ensuring fast delivery of heat exchanger systems for the chemical processing, power generation, and HVAC industries, where reliability, thermal efficiency, and leak-free performance are paramount.
