A53 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 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.
