一，Spiral steel pipe
- Spiral steel pipe is made of strip steel coil as raw material, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding process to form a spiral seam steel pipe.
二， Process characteristics
- The processed spiral steel pipe has greater flexibility in the size specification range of diameter and wall thickness, which can meet more requirements of users.
- The advanced double-sided submerged arc welding process can achieve welding in the best position, and it is not easy to have misalignment, welding deviation and other phenomena, and the welding quality can be controlled.
- 100% quality inspection of steel pipes ensures that the production process is effectively detected and controlled, effectively ensuring product quality.
- The data acquisition system of the entire production line has real-time data transmission, and the technical parameters of the production process are centrally controlled.
三，Stacking principles
Stack by type and specification to prevent confusion and mutual erosion
The bottom of the stack should be raised, solid and flat to prevent the material from getting damp or deformed
The stacking height shall not exceed 1.2m for manual operation, 1.5m for mechanical operation, and the stack width shall not exceed 2.5m
