Applications of welded pipe piles and Testing and Materials
Applications of Steel Pipe
Steel pipe offers mechanical and physical characteristics that make it one of the most versatile construction products available. As a structural element, steel pipe remains unrivaled when compared to alternate materials. The flexibility
offered by the manufacturing process, quality control and low production cost positions spiral weld and rolled and welded pipe to be the new shape of steel in many industries.
ASTM A252 Scope “This specification covers 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 cast-in-place concrete piles.”
Material & Manufacture “The piles shall be made by the seamless, electric resistance weld, flash weld, or fusion welded process. The seams of welded pipe piles shall be longitudinal, helicalbutt, or helical-lap.”
ASTM A572 Scope “This specification covers five grades of high-strength lowalloy structural steel shapes, plates, sheet piling, and bars. Grades 42 [290], 50 [345], and 55 [380] are intended for riveted, bolted, or welded structures. Grades 60 [415] and 65 [450] are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.”
ASTM A690 Scope “This specification covers high-strength low-alloy nickel, copper, phosphorus steel H-piles and sheet piling of structural quality for use in the construction of dock walls, sea walls, bulkheads, excavations, and like applications in marine environments.”
ASTM A139 Scope “This specification covers five grades of electric-fusion (arc)-welded straight-seam or helical-seam steel pipe. Pipe of NPS 4 and larger with nominal (average) wall thickness of 1.0 in. [25.4mm] and less are covered. Listing of standardized dimensions are for reference. The grades of steel are pipe mill grades having mechanical properties which differ from standard plate grades. The pipe is intended for conveying liquid, gas or vapor.”
ASTM A1011 Scope “This specification covers hot-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, and ultra-high strength steel sheet and strip, in coils and cut lengths.”
ASTM A1018 Scope “This specification covers hot-rolled, heavy-thickness coils beyond the size limits of Specification A1011/A1011M.”
AWWA C200* Scope “This standard describes electrically butt-welded straight-seam or spiral-seam pipe and seamless pipe, 6 in. (150mm) in nominal diameter and larger, for the transmission and distribution of water or for use in other water system facilities.”
