Spiral steel pipe main process characteristics:
A. Forming process, the steel plate deformation uniformity, the residual stress is small, the surface does not produce scratches. Processing of spiral steel pipe in the diameter and wall size specifications on the scope of greater flexibility, especially in the production of high-grade thick-walled thick-walled tubes, especially in small and medium-sized thick-walled tube with other technology can not match the advantages to meet the user Spiral steel pipe specifications in more requirements.
B. The use of advanced double-sided submerged arc welding process can be achieved in the best position welding, not easy to be wrong side, welding and welding defects such as partial and not easy to control the welding quality.
C. 100% of the steel pipe quality inspection, so that the whole process of steel production are in the effective detection and monitoring, effectively ensuring product quality.
D. The whole equipment of the whole production line has the function of networking with the computer data acquisition system and realizes the data transmission in real time, and the technical parameter in the production process from the central control room.
