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. Generally speaking, there are three kinds, the Ministry standard SY /5037, the national standard GB /9711, and the American standard API-5L, which are generally used for export, have different functions and different testing standards. The testing process of spiral steel pipe is determined according to the customer needs of spiral steel pipe.

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.
