ASTM A252 is a standard specification for seamless and welded carbon steel pipe piles developed by the American Society for Testing and Materials (ASTM).
The ASTM A252 standard covers different grades of mechanical structural pipes, including GR.1 and GR.2, which are commonly used in piling and civil engineering.
GNEE supplies ASTM A252 piling pipes in various specifications, including seamless steel pipes, ERW steel pipes, SSAW steel pipes, and LSAW steel pipes, with a variety of options for outer diameter and wall thickness to meet different engineering needs.
ASTM A252 seamless steel pipes have an outer diameter range of 21.3 mm to 1473 mm and a wall thickness range of 2 mm to 300 mm.
ASTM A252 ERW steel pipes have an outer diameter range from 33.4 mm to 609.6 mm and a wall thickness range of 2 mm to 30 mm.
The outer diameter of ASTM A252 SSAW steel pipes ranges from 219 mm to 3200 mm, and the wall thickness ranges from 5 mm to 30 mm.
The outer diameter of ASTM A252 LSAW steel pipes ranges from 457 mm to 1422 mm, and the wall thickness ranges from 8 mm to 50 mm.
