1. In the process of steel saw forming, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched. Processing steel pipe has more flexibility in the scope of pipe diameter and wall thickness, especially in the production of high-grade thick-walled steel pipe, especially in large-diameter thick-walled steel pipe, which has other incomparable advantages. The process can be satisfied. Users have more requirements for steel pipe specifications.


2. The process of internal and external welding (precision welding) after pre-welding can be used to realize welding. It is not easy to produce defects such as misalignment, welding deviation and incomplete penetration, and it is easy to control welding quality.


3. Integral mechanical expansion can effectively improve the dimensional accuracy of steel pipe, improve the stress distribution in steel pipe, avoid damage caused by stress corrosion, and be conducive to on-site welding structure.


4. 9 quality inspections were carried out to ensure the effective inspection and monitoring of the whole process of steel pipe production, and the quality of SAW pipes was effectively guaranteed.


5. The whole equipment of the whole production line has the function of networking with the computer data acquisition system, realizing real-time data transmission, and the central control room controls the technical parameters and quality indicators in the production process.
