A252 Seamless&Welded Pipe Piles Description
ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. Welding mainly provides ASTM A252 submerged arc welded steel pipe piles for agricultural, construction and load bearing geotechnical applications. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.
