SSAW spiral welded pipe includes ordinary spiral steel pipe and thick wall spiral steel pipe.The advantages of thick-walled spiral steel tubes compared with ordinary thick-walled spiral steel tubes are: high compressive strength, high impact strength, high safety performance and long service life.The strength of SSAW spiral welded pipe is generally higher than that of straight seam welded pipe, and larger diameter welded pipe can be produced from narrower billets, or different diameters welded pipe can be produced from billets of the same width.SSAW spiral welded pipe nominal diameter, also known as the average outside diameter.This is because the wall of the metal pipe is very thin, the outer diameter of the pipe and the inner diameter of the pipe are almost the same, so take the average of the outer diameter of the pipe and the inner diameter of the pipe as the diameter of the pipe.

Surface: Fusion bond Epoxy coating, Coal Tar Epoxy, 3PE, Vanish Coating,The processed spiral steel pipe has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-steel grade thick wall pipe, especially in small and medium-sized thick wall pipe has incomparable advantages, which can meet the user's more requirements in the specification of spiral steel pipe.Adopting the advanced double-sided submerged arc welding technology, the welding can be realized in the optimal position, and it is not easy to have the defects such as wrong side, deviation and incomplete welding, etc., and easy to control the welding quality.
