ASTM A252 Welded And Seamless Steel Pipe Piles

Views: 16    

ASTM A252 is pipe piling material standard that has been widely used in constructions and structural buildings.This specification covers nominal thickness of the wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member, or as a shell to form cast-in-place concrete piles. A252 specification includes three grades (1, 2, and 3), Grade 3 pipe piling material is the most used option.

ASTM A252 pile pipe material and manufacturing types

(1)Raw material making process

Raw material iron and steel could be made through the process of Open-hearth, Basic-oxygen, Electric-furnace.

(2)Seamless pipe pile

Seamless pipe pile referred as hot rolled or cold drawn and thermal expanded seamless pipe.

(3)Welded pipe pile

Welded pipe pile including ERW (electric resistance welded), flash welded, fusion welded or sub-merged welded SSAW or LSAW. Longitudinal or helical spiral welded.

The advantages of  a252 steel piling pipe

A252 steel piling pipe is used for dredging, slurry, water and other pipelines, as well as piling and structural applications.

A252 steel piling pipe is produced in accordance with the dimensional and tolerance requirements of various ASTM, AWWA, and API Specifications.
