Structural Service Steel Pipe

Structural steel pipe refers to the steel pipe mainly used in general engineering structure and mechanical structure.Carbon structural pipes are mainly used in factories, bridges, ships and other buildings, such steel is generally used directly without heat treatment. Because of its high strength and comprehensive mechanical energy, alloy structural pipes are widely used in bridges, ships, boilers, vehicles and important building structures. Structural stainless-steel seamless steel pipe is widely used in chemical, petroleum, textile, medical, food, machinery and other industries corrosion-resistant pipes and structural parts.According to the manufacturing method can be divided into seamless structure pipe and welded structure pipe. According to the shape can be divided into circular, square, rectangular, oval and other irregular shapes. 1 ASTM A134 Electric-Fusion (Arc)-Welded (Sizes NPS 16 and Over) Steel Pipe 2 ASTM A139 Electric-Fusion (Arc)-Welded Steel Pipe (NPS 4 and Over) 3 ASTM A252 Welded and Seamless Steel Pipe Piles 4 ASTM A500 Cold-Formed Structural Tubing in Rounds and Shapes 5 ASTM A501 Hot-Formed Welded and Seamless Carbon Steel Structural Tubing 6 ASTM A618 Hot-Formed Welded and Seamless Carbon Steel Structural Tubing 7 EN 10210 Hot Finished Structural Hollow Section of Non-alloy and Fine Grain Structural Steel 8 EN 10219 Cold Formed Welded Structural Hollow Sections of Non-alloy and Fine Grain Steel 9 JIS G3444 Carbon Steel Tubes for General Structure Purposes 10 JIS G3445 Carbon Steel Tubes for Machine Structure Purposes 11 JIS G3446 Stainless Steel Pipe for Machine and Structural Purposes 12 JIS G3475 Carbon Steel Tubes for Building Structure 13 GB/T 3094 Cold Drawn Shaped Steel Tubes 14 GB/T 8162 Seamless Steel Tube for Structure Purposes 15 GB/T 14975 Seamless Stainless Steel Tube for Structural 16 GB/T 18705 Welded Stainless Steel Pipes for Decoration 17 GB/T 30063 Longitudinal Submerged Arc Welded Steel Tubes for Structural Purpose 18 GB/T 34201 Seamless Hot-Rolled Square and Rectangular Steel Tubes for Structure
