Product Introduction

ASTM A269 TP316L tube is a high-quality steel tube that meets the ASTM (American Society for Testing and Materials) A269 standard specification and has excellent corrosion resistance and strength characteristics. The low carbon content of UNS S31603 material also provides better resistance to intergranular corrosion and welding performance. SS 316L tube is available in two types: seamless or welded, and is widely used in many industries such as oil and gas, chemicals, food and pharmaceuticals.

ASTM A269 TP316L Stainless Steel Tube Standard:

ASTM A269: Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service

ASME B36.19：Specification for stainless steel pipes

Available forms for 316L: Stainless Steel Fittings, Flanges, Forgings, Fasteners, Pipes, Tubes, Plates, Sheets, Strips, Coils, Bars, Round Rods, Etc.

Advantages of Seamless Tube:

ASTM A269 SS 316L seamless tube is a pipe made by perforating heated steel billets. The weld seam is eliminated, providing greater strength and pressure resistance to the pipeline system, and also has high processing accuracy.

Advantages of Welded Tube:

AISI 316L welded pipe can be welded by different methods, such as TIG welding, ERW welding, LASER welding, etc. Compared with seamless pipe, welded pipe is suitable for some large-scale pipeline projects, can be made of large diameter sizes, and has lower cost.
