ASTM A269/A296M-15 TP304/TP304L Stainless Steel Seamless Tube for Heat Exchanger and Boiler

ASTM A312 Tp304l Stainless Steel Pipe is one of the most widely used steel pipes in the world for many reasons. The ASTM A312 Gr Tp304l is cheaper than most other stainless steel products and therefore is cost effective. It is an austenitic stainless steel and has chromium content in it. This makes the ASTM A312 Grade Tp304l corrosion resistant. This quality is desired in most applications. The A312 Tp304l Pipe can be produced in different methods and it could come in different shapes as well.

Specifications: ASTM A/ASME SA213/A249/A269/A312/A358 Pipes and Tubes Sizes (Seamless): 1/2" NB - 16" NB

Pipes and Tubes Sizes (ERW): 1/2" NB - 24" NB

Pipes and Tubes Sizes (EFW): 6" NB - 100" NB

Pipes and Tubes Wall Thickness available: Schedule 5S - Schedule XXS (heavier on request)

Pipe and Tubes Other Materials Testing: NACE MR0175, H2 SERVICE, OXYGEN SERVICE, CRYO SERVICE, etc.

Dimensions: All Pipe is manufactured and inspected/tested to the relevant standards including ASTM, ASME and API etc.
