A252 Seamless&Welded Pipe Piles

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. 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. The chemical composition of A252 steel pipe mainly consists of iron, carbon, silicon, manganese and other elements, of which the carbon content is low, only about 0.2%. A252 steel pipe piles has excellent mechanical properties, high strength and toughness, tensile strength is generally between 400-550MPa, and has good low-temperature toughness. A252 seamless welded pipe piles play an important role in petroleum, chemical industry, machinery, construction and other fields.
