A252 Straight Seam Welded Round Pipe

ASTM A252 Straight Seam Welded Pipe is a standard for steel pipe piles used in construction. It is available in Grades 1, 2, and 3, with Grade 3 being the highest in yield and tensile strength . These pipes are either seamless or welded, with electric resistance welding (ERW) being a common method . They are designed for load-bearing structures or as casing for concrete piles and are known for their reliability and durability.

For ASTM A252 Straight Seam Welded Pipe, material selection is governed by specific standards to ensure the pipe's integrity and performance. The key standards and criteria include:

ASTM A252 Specification: This standard covers the manufacturing process where the steel cylinder acts as a permanent load-carrying member or as a shell to form cast-in-place concrete piles .

: The steel shall contain no more than 0.050% phosphorous, which is crucial for weld quality .

These standards ensure that the raw materials used in the production of ASTM A252 pipes are of high quality and suitable for their intended structural applications.
