Carton Anti-Corrosion Welded Carbon Spiral Steel Pipes Large
Diameter Tubes ASTM A252 Grade 3 Spiral Steel Pipes
Spiral pipe, also known as spiral steel pipe or spiral welded pipe,
is made of low carbon structural steel or low alloy structural
steel strip rolled into a pipe billet at a certain angle of the
spiral line (called the forming angle) and then the pipe seam is
welded together, which can produce large diameter steel pipes from
narrower strips of steel.
Spiral pipes are mainly used for oil and gas transmission
pipelines, and their specifications are expressed in terms of outer
diameter * wall thickness. Spiral pipe has single-sided welded and
double-sided welded. The welded pipe should ensure that the
hydraulic test, tensile strength of the weld seam and cold bending
performance meet the requirements.
Spiral pipes are mainly used in water supply engineering,
petrochemical industry, chemical industry, electric power industry,
agricultural irrigation and urban construction, and are one of the
twenty key products developed in China. For liquid conveying: water
supply, drainage, sewage treatment works, mud transport, marine
water transport. For gas transportation: gas, steam, liquefied
petroleum gas. For structural use: piling pipes, bridges, docks,
roads, building structures, marine piling pipes, etc.
