Main technical characteristics of dsaw steel pipe

First, the steel pipe forming process, the steel plate deformation uniform, residual stress is small, the surface does not produce scratches. The machined steel pipe has greater flexibility in the size and thickness of the steel pipe, especially in the production of high-grade thick-walled steel pipes, especially large-diameter thick-walled pipes, which can meet the advantages of other processes Users in the steel specifications more requirements;

Second, the use of pre-welding after welding (welding) of the process, in the best location to achieve welding, not prone to wrong side, welding and not welding and other defects, easy to control the quality of welding;

Third, the overall mechanical expansion, can effectively improve the dimensional accuracy of steel pipe and improve the distribution of stress in the steel pipe, so as to avoid damage caused by stress corrosion, while the site is conducive to welding construction;

Fourth, the steel pipe for nine 100% of the quality inspection, so that the entire process of production of steel pipe are effective in the detection, monitoring under the effective guarantee of submerged arc welded pipe product quality;

Fifth, the entire production line of all the equipment and computer data acquisition system with the network function, to achieve real-time data transmission, the central control room on the production process of technical parameters and quality indicators for mining quality.
