Characteristics of spiral welded steel pipe
Date:2012/4/27 Click :3195 time(s) Keywords:steel-pipelines.com
Spiral welded steel pipe is also known as the spiral steel pipe and spiral welded pipe,which is use low carbon structural steel or low alloy steel strip according to the angle of the spiral line (called the forming angle) rolled into a tube, and then the tube welded together made, it can be a narrow strip production of large diameter steel pipe. The coil is mainly used for oil and gas pipelines, its specifications OD * wall thickness. Side welding and double-sided welding spiral welded pipe should ensure that the hydrostatic test, the tensile strength of the weld and cold bending performance required.
(1)the pressure fluid transmission spiral submerged arc welded pipe: mainly used for transporting oil, natural gas pipeline;
(2)the pressure fluid transmission high frequency welded steel pipes with spiral seam: welded high-frequency lap welding method for pressure fluid transmission spiral high-frequency welded steel pipe. Ability of steel pipe under pressure, good plasticity, the ease of welding and molding process;
(3)low pressure fluid transmission spiral submerged arc welded steel pipe: double-sided automatic submerged arc welding or single-sided welding into the legal system for low pressure fluid such as water, gas, air and steam with submerged arc welded pipe.
