We are committed to providing one-stop service for steel pipe products to customers around the world.
ASTM A252 is the standard specification for
welded and seamless steel pipe piles. It covers the nominal wall thickness of
cylinder shape steel pipe, rectangular pipe is not included. These round pipes
are used for piling purposes, playing as a permanent role of load carrying and
bearing the pressure. Furthermore, to act as a tank shell to fill with the
concrete piles at sight of the project.
