Pipe Pile - an overview | ScienceDirect Topics

Pipe piles can be fabricated as extruded or rolled thin-walled pipe piles, spiral welded steel, extruded steel, and rolled steel (ASTM A252, Standard Specification for Welded and Seamless Steel Pipe Piles) The available size range of pipe piles and the stiffness that can be increased by increasing the pipe wall thickness has made them desirable for major bridge foundations
