ASTM A53 Pipe

ASTM A53 pipe, a standard specification for black and hot-dipped, zinc-coated, welded and seamless  steel pipe, is used for mechanical and pressure applications as well as ordinary uses in steam, water, gas and air lines. ASTM A53 can be formed and welded. Pipe sizes are properly designated using the Nominal Pipe Size (NPS).  This is the nominal pipe diameter with a scheduled wall thickness (i.e., 4 inch Schedule 40 pipe).

 

CHARACTERISTICS

Designed for coiling, bending and flanging, A53 carbon steel pipe is suitable for welding. The grades denote certain chemical and mechanical properties and should be noted in selection.

APPLICATIONS

A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. 

SIZES

½” – 12” some limitations dependent upon grade. Sizes up to 26” OD are available on limited basis.

Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe.

ASTM A53 PIPE TYPES

The following types & grades of A53 pipe are covered within this specification:

  • Type F – Furnace-butt-welded, continuous welded Grade A
  • Type E- Electric-resistance-welded, Grades A and B
  • Type S- Seamless, Grades A and B
  • Round HSS have a superior surface finish and do not come with the lacquer coating that typically comes on A53 pipe.  This saves money and time as this lacquer coating needs to be removed from the A53 pipe to accommodate welding and painting.

    A53 pipe are only available in standard pipe sizes.  Round HSS come in a variety of sizes and wall thicknesses.  Just take a look at the 14th edition of the AISC Steel Construction Manual and see how many pages of round HSS there are versus the number for A53 Pipe.

    Lastly, the ASTM A53 Specification requires testing (i.e., pressure testing) that is not needed for structural applications.  This additional testing can add unnecessary additional cost.
