PRODUCT DESCRIPTION
Standard for ERW Steel Pipe
ASTM A53 standard is Steel, Pipe,Black and Hot-Dipped Zinc-Coated Steel Pipes Welded and Seamless.
ERW steel pipe is a steel pipe rolled by steel plate and welded by high frequency welding, mainly for ordinary wall thickness and thin wall thickness steel pipe, with precise wall thickness and light weight.
ERW steel pipes are mainly used for the transportation of water, oil and gas, and can also be used for structures and can be welded.

1. For pipe ≤ NPS 1-1/2", OD tolerance is ±0.4mm.

2. For pipe ≥ NPS 2", OD tolerance is ± 1%.

3. The min THK at any point is not more than 12.5%.

4. The max THK is not defined in ASTM A795, and Baolai refers to ASTM A530  with 20%, 22.5% or 15% as t/D ratio.
