What is ASTM A252 pipe
ASTM A252 is the standard specification for welded and seamless steel pipe piles. It covers the nominal wall thickness of cylinder shape steel pipe, rectangular pipe is not included. These round pipes are used for piling purposes, playing a permanent role in load carrying and bearing the pressure. Furthermore, to act as a tank shell to fill with the concrete piles at the sight of the project.

The manufacturing process of ASTM A252 pipe
Steel coils→Ray material test → Delivery straightening → Plate cutting and welding → circle shear edge milling → Forming → inside auto-welding → Outside auto-welding → Online ultrasonic inspection → Fixed length cutting → Visual inspection for outside seam → Visual inspection for inside seam → X-ray inspection for welding seam → Even end and end bevel → Hydrostatic test → Ultrasonic inspection → Final product inspection → Marking → Store up
Standard of ASTM A252 pipe
1. ASTM A370 inspection methods and definitions for the mechanical tests of steel products.
2. ASTM A751: Chemical analysis test methods.
3. ASTM A941: Terminology for carbon, alloy, and stainless steel.
4.E29 practice for using significant digits in test results to decide the conformance with the specification.
Application of ASTM A252 pipe
- Buildings
- Retaining walls
- Different structures that need a tough base
