Cold Formed Welded Spiral Steel Fine Grain Standard Hollow Section Ssaw Steel Pipe


Spiral steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, is one of the 20 key products developed in China.For liquid transport: water supply, drainage. For gas transmission: gas, steam, liquefied petroleum gas. For structural use: as pile driving pipe, as bridge; Pipes for wharves, roads, building structures, etc.SSAW Steel Pipe (Spiral steel tube) is a spiral welded steel tube made of strip steel coil as raw material, usually formed by warm extrusion, and welded by automatic double-wire double-side submerged arc welding process.


The spiral steel tube feeds the strip into the welding tube unit, and after rolling with multiple rollers, the strip is gradually rolled up to form a round tube blank with open clearance. The pressure reduction of the extrusion roller is adjusted so that the weld clearance is controlled at 1~3mm and both ends of the welding joint are flush.Main technological features of spiral steel tube:In the forming process, the steel plate deformation uniformity, the residual stress is small, the surface does not produce scratches.


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.100% quality inspection is carried out to ensure the whole process of steel pipe production under effective testing and monitoring, thus effectively ensuring the product quality.

Grade can be SS400 s235,s355/L245(B),L290(X42),L320(X46),L360(X52),L390(X56),L415(X60),L450(X65),L485(X70),L555(X80).
