What is ASTM A53 Steel Pipe

Identical to ASME SA-53, ASTM A53 steel pipe is the standard specification for seamless and welded black and hot-dipped galvanized (zinc-coated) steel pipe in NPS 1/8 (DN 6) to NPS 26 (DN650) with nominal wall thickness. The steel pipe having other dimensions can also be furnished provided that such pipe complies with all other requirements of the specification. The “black steel” refers to a dark-colored iron oxide scaly appearance which naturally results from the pipe’s fabrication process. The hot-dipped galvanization is provided for corrosion protection purposes.

A53 Steel Pipe Raw Material – Carbon Steel Pipe

The steel for making ASTM A53 pipe (both for seamless and welded) shall be according following processes: open hearth electric furnace, or basic oxygen.

Raw steel material of different grades are independently strand cast identification of resultant transition material is needed. Manufacturer should remove transition material by any established procession that could clearly separate the grades.

The welding seam for ERW welding processes in ASTM A53 Grade B pipe should be done heat treatment after welding to a min of 540(1000).

Consequently, there is no untempered martensite remains, or use the other ways of non untempered martensite remains.

For cold expanded, the expansion amount shall not exceed 1 1/2% of the pipe diameter.

Material Types for ASTM A53 Steel Pipe Standard

a. Seamless Type S, has grade A and B.

b. Welded Type E (ERW), Grade A and B.

c. Furnace Welded Type F, Grade A only.

Hot-dipped Galvanizing:

Sets standards for coating of pipe with zinc inside and outside by the hot-dipped process. Weight of coating must not average less than 1.8 oz. per square foot and not less than 1.6 oz. per square foot.


The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
