• A53 pipe raw material - carbon steel pipe

Steel used in the manufacture of ASTM A53 pipe, including seamless and welded pipe, shall be manufactured using the following processes: Open-air electric furnace or alkaline oxygen furnace.

Different grades of steel raw materials should be cast independently, and the cast transition materials should be identified. The manufacturer shall remove transitional materials through any established process that clearly distinguishes grades.

ASTM A53 Grade B steel pipe ERW welding process welds shall be heat treated after welding to a minimum temperature of 540℃ 1000℉.

Therefore, no untempered martensite shall remain, or no untempered martensite shall remain by other means.

For cold expansion, the amount of expansion must not exceed 1.5% of the pipe diameter.

• ASTM A53 Standard Material Types

a. Seamless S type, available in Grade A and Grade B.
b. Welding Type E (ERW), Class A and Class B.
c. Furnace welded type F, grade A only.
