Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless
ASTM A53 (ASME SA53) carbon steel pipe is a specification that covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8″ to NPS 26. A 53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.
A53 pipe comes in three types (F, E, S) and two grades (A, B).
A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)
A53 Type E has an electric resistance weld (Grades A and B)
A53 Type S is a seamless pipe and found in Grades A and B)
A53 Grade B Seamless is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.
A53 Comparative Specifications
ASTM Specification A53 covers seamless and welded, black and hot-dipped galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. U. S. Steel Tubular Products does not produce galvanized pipe.

We are interested to get more information about black steel & galvanized pipes, beside any other products you are dealing or manufacturing. Do you have customers or dealers in the Gulf region particularly in Dubai ????
