Spiral welded steel tubes are widely used in oil, natural gas, water and other flammable & nonflammable liquid conveyance and distribution pipelines, steel structures for construction and other general purposes by means of their wide size range.

a. Molding process, the steel deformed uniformly, spiral steel tube, residual stress, the surface does not produce scratches. Spiral steel tube processing diameter and wall thickness in the range of sizes for greater flexibility, especially in the production of high grade thick-walled pipe, spiral steel tube, especially small and medium-diameter thick-walled tube has advantages over other processes, to meet user specifications in steel demand more.

b. The use of advanced double-sided submerged arc welding process, welding can be achieved in the best position, less prone to the wrong side, partial and incomplete penetration welding defects, easy to control weld quality.

c. 100% of the steel quality inspection, so that the whole process of steel production were effective detection, monitored effectively to ensure product quality.

d. All of the entire production line equipment and computer data acquisition system with networking capabilities, real-time data transmission by the central control room on the technical parameters of the production process and quality indicators for the whole process of acquisition and implementation of real-time monitoring, to ensure maximumproduct quality, spiral steel tube.
