ASTM A213 Gr 317 Boiler Tubes Manufacturer

As a manufacturer and leading supplier of 317/317L stainless steel pipes, GNEE offers a comprehensive product range covering multiple standards and specifications to meet one‑stop needs from general industry to special equipment applications. Our seamless pipes comply with ASTM A269, A312, and A213, while our welded pipes cover ASTM A358, A249, A409, and A778.

We supply high‑quality ASTM TP317L stainless steel heat exchanger tubes with nominal inside diameters from ½" to 8"; the combination of wall thickness and diameter determines the pressure rating and schedule number (5S to XXS) to suit various operating pressure conditions. Among them, SS 317L U‑tubes are specially optimized for heat exchangers - their U‑shape allows multi‑row arrangements, improving heat transfer efficiency and space utilization.

The ASTM A213 TP317L stainless steel seamless pipe has a melting point as high as 1454 °C, enabling it to maintain strength and oxidation resistance over long periods in high‑temperature environments. 317L alloy welded pipes are easier to weld and retain stable corrosion resistance after welding, helping to reduce maintenance costs. The ASTM A269 TP317 specification covers pipes and tubes for boilers and heat exchangers, and the corresponding products are also known as ASME SA213 TP317L boiler tubes, superheater tubes, heat exchanger tubes, and condenser tubes, widely used in high‑temperature, high‑pressure heat transfer and fluid transport applications.
