ASTM A252 Welded Steel Pipe Piles Information
ASTM A252 is a standard specification for welded and seamless steel pipe piles. It covers nominal wall thickness, grade, and type of steel.
Steel pipe piles can be either welded or seamless and are available in various diameters and wall thicknesses to suit different load-bearing requirements. They are commonly used in construction projects where the soil conditions require deep foundation support, such as in coastal areas, riverbanks, or areas with soft or loose soil.
