What is SA 249 TP316L material?

What is SA 249 material?

ASTM A249 / A249M Covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels listed in standard, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.

 

What is SA 249 TP 316L Stainless Steel Welded Pipe?
ASME SA 249 TP 316L Stainless Steel Welded Pipe is a type of stainless steel pipe manufactured to ASME SA 249 specifications and connected by welding. This pipe is a low-carbon version of 316 stainless steel alloy and offers excellent resistance to corrosion and intergranular corrosion, especially in harsh environments. It is commonly used in high-pressure applications, heat exchanger systems, and applications involving corrosive compounds such as salt water.

Application

ASME SA 249 TP316L stainless steel tube is applied in the condenser, boiler, superheater, heat exchanger, and other pressure equipment, TP316L stainless steel has high strength and corrosion resistance characteristics compared to typical Austenitic stainless steel 304. The tubes can work under high temperatures and corrosive environments, of course, the TP316L tube is a good option, and it is durable and cost-effective.

 

ASME SA249 Grade 316L welded pipe is manufactured from rolled plate or strip and then welded using standard shop welding procedures. These versatile pipes must be tested before use in high-pressure systems. ASME SA249 Gr 316L ERW welded pipes are manufactured with a longitudinal seam, where an electric current is passed through the metal layers to weld them in place. These pipes can be welded in place without any filler material. If you have any questions about our products or would like a quote, please contact us today! Email: sales@gneestainless.com
