ASTM A252 Steel Pipe Pile
ASTM A252 Welded Steel Pipe Pile Manufacturer
Huayang Steel Pipe manufactures ASTM A252 welded steel pipe piles for foundation engineering, marine construction, bridge projects, and heavy-duty structural applications.
ASTM A252 is the standard specification for welded and seamless steel pipe piles. The specification defines requirements for steel pipe piles used as load-bearing structural members, especially in deep foundation systems where high strength, durability, and dimensional stability are required.
With advanced double-sided submerged arc welding technology, JCOE and RBE forming processes, Huayang produces large diameter ASTM A252 steel pipe piles with excellent welding quality and reliable structural performance.
ASTM A252 Steel Pipe Pile Grades
ASTM A252 mainly includes three grades according to mechanical properties.
| Standard | Grade | Yield Strength | Tensile Strength | Application |
|---|---|---|---|---|
| ASTM A252 | Grade 1 | 205 MPa min | 345 MPa min | General foundation piling |
| ASTM A252 | Grade 2 | 240 MPa min | 414 MPa min | Heavy load foundation |
| ASTM A252 | Grade 3 | 310 MPa min | 455 MPa min | High strength piling projects |
