 We supply ASTM A252 Class 1, Class 2, and Class 3 pipe piles. Suitable for infrastructure development sectors such as construction, oil, and gas industries.
Available in sizes up to 56 inches. Steel pipe types are SMLS or ERW, LSAW, and SSAW.
These pipes are of seamless construction, resistance welded, flash welded, or fusion welded, and may have a longitudinal, spiral butt, or spiral lap joints.
These steel pipes are designed to be used as permanent load-bearing members or as casings for cast-in-place concrete piles. They are cylindrical with nominal walls and are engineered to withstand the test of time and provide superior performance in various conditions.

Grade 3 steel pipe piles are not limited to a specific production process and can be manufactured using a variety of pipe fabrication methods, including SMLS (seamless), SAW (submerged arc welded), and EFW ( electro-fusion welded). This flexibility allows it to be adapted to different engineering needs and application scenarios.

As the highest grade in the A52 standard, it has excellent mechanical properties with a minimum yield strength of 310 MPa and a minimum tensile strength of 455 MPa and can be used as a permanent load-bearing structural component or as a shell for cast-in-place concrete piles.

ASTM A252 Grade
The ASTM A252 standard categorizes steel pipe piles into three grades to suit different application environments and loading requirements. The three grades are:

Grade 1, Grade 2, and Grade 3.

Pipe End
Pipe piles shall be plain end.

The ends shall be flame-cut or machine-cut and deburred.

In the case of beveled ends, the angle of the beveled end should be 30 - 35°.

Manufacturing Process of ASTM A252
A252 shall be made by the seamless, electric resistance welded, flash welded, or fusion welded process.

The seams of welded pipe piles shall be longitudinal, helical-butt, or helical-lap.

To ensure the quality and performance of steel pipe piles, it is critical to select the correct production process.

The LSAW (SAWL) process is ideal for large-diameter, thick-walled steel pipe, especially in construction and infrastructure projects that require high load-bearing capacity and deep foundation construction. Due to its superior strength, load-carrying capacity, and depth adaptability, it is able to adapt to a wide range of complex geologic conditions while providing the benefits of quick installation and long-term durability.
