ASTM/ASME A252/SA252 Piling Pipe
Our standard and line pipe manufacturing processes ensure the highest quality in end products.
U. S. Steel Tubular Products ASTM/ASME A252/SA252 steel piling pipe is a structural pipe ideally suited for application in buildings, retaining walls, and other structures needing solid, dependably, quality made steel piling pipe as its structure.
We are the largest,
fully integrated energy tubular producer in North America . U. S. Steel has full control over every step of the pipe manufacturing process, from melt to final product. We manufacture our tubular products at several U.S.-based facilities that produce high-quality tubular products with low-residuals in a wide range of strength levels with superior toughness.
Because we are domestically produced, our customers are assured of the highest levels of quality and have access to concerned and invested customer service.
A252 Comparitive Specifications
ASTM Specification A252 describes nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member or as a shell to form case-in-place concrete piles.
Surface imperfections exceeding 25% of the nominal wall in depth are considered defects. Defects not exceeding 22.5% of the nominal wall in depth may be repaired by welding. Before welding, the defect shall be completely removed.
