Ordering Information
When ordering ASTM A252 pipe piles, include:
Quantity (feet or number of pieces)
Product name (steel pipe pile)
Manufacturing method (Seamless / ERW / LSAW / SSAW)
Grade (A252 Grade 1, 2, or 3)
Dimensions (Outside Diameter + Wall Thickness)
Weight requirements (e.g., weigh each piece, theoretical weight, etc.)
ASTM A252 Grades Overview
| Grade | Description |
|---|---|
| Grade 1 | Lowest strength; suitable for lighter structural applications |
| Grade 2 | Medium strength; commonly used in civil engineering projects |
| Grade 3 |
Highest strength; most widely used for demanding piling applications |
ASTM A252 Applications
ASTM A252 mainly manufactures welded and seamless Spiral Steel Pipe or Straight Seam Submerged Arc Welded (SSAW) pipes. These steel pipes are commonly used in civil and structural engineering infrastructure. They are especially used in the construction of pile foundations.
Specifically, the ASTM A252 standard covers three grades of pipe. These grades of pipe are typically used in the following applications:
Pile Foundation: ASTM A252 steel pipe is commonly used in pile foundation projects to support the basic structures of buildings, bridges, docks, etc.
Civil Engineering: In some civil engineering projects, such as river embankment protection, drainage systems, and foundation reinforcement, ASTM A252 standard steel pipes are also widely used.
Oil and gas transportation: In some cases, ASTM A252 steel pipes can also be used in oil and gas transportation pipelines, especially under special geological conditions.
