Spiral steel column

Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip into the welded pipe unit. After rolling by multiple rollers, the strip is gradually rolled up to form a circular tube blank with an opening gap. 3mm, and make both ends of the welding joint flush.
 

·During the forming process, the deformation of the steel plate is uniform, the residual stress is small, and the surface is not scratched. The processed spiral steel pipe has greater flexibility in the size range of diameter and wall thickness, especially in the production of high-grade steel-grade thick-walled pipes, especially medium- and small-diameter thick-walled pipes, which have incomparable advantages in other processes, which can meet the needs of users. More requirements in terms of spiral steel pipe specifications.
 
·Using the advanced double-sided submerged arc welding process, the welding can be realized in the best position, and it is not easy to have defects such as misalignment, welding deviation and incomplete penetration, and it is easy to control the welding quality.
 
·100% quality inspection is carried out on the steel pipe, so that the whole process of steel pipe production is under effective inspection and monitoring, which effectively guarantees the product quality.
 
·All equipment of the entire production line has the function of networking with the computer data acquisition system to realize real-time data transmission, and the technical parameters in the production process are checked by the central control room.
