ASTM A53 GRB steel pipe

ASTM A53 Grade B Pipe is a material grade of carbon steel pipes that are intended for low pressure services such as plumping.

The ASTM A53 Grade B is one of the most used because of the medium level pressure containment capacities. The pipes are used in water supply, irrigation, sea water and waste water management systems alike. The corrosion resistance is low compared to other alloys, but the toughness and wear and tear resistance are higher.

The ASTM A53 Grade B ERW Pipes is electric resistant welded and the size could range up to 100 inches in some cases for the ERW pipes. The usual range is 1/8 inches to 26 inches in diameter.

 

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.
