LSAW

"LSAW steel pipe" is the main technological characteristics of LSAW steel pipe:

1 During the steel pipe forming process, the steel plate has uniform deformation, small residual stress and no scratch on the surface. Processed steel pipe
There is greater flexibility in the size range of steel pipe with diameter and wall thickness, especially in the production of high grade thick wall
Steel pipes, especially large-diameter thick-wall pipes, have advantages that other processes can not match, and can meet the needs of users in steel
More requirements for pipe specifications;

2. The process of pre-welding before internal and external welding (finish welding) can be used to realize welding at the best position, and it is not easy to have wrong edges
Defects such as welding deviation and incomplete penetration are easy to control the welding quality;

3. The overall mechanical expansion can effectively improve the dimensional accuracy of the steel pipe and improve the distribution of the internal stress of the steel pipe
State, so as to avoid damage caused by stress corrosion, and at the same time, it is conducive to on-site welding construction;

4. Carry out 9 100% quality inspections on steel pipes, so that the whole process of steel pipe production is under effective inspection and supervision
Under control, the product quality is effectively guaranteed;

5. All equipment of the whole production line has the function of networking with the computer data acquisition system to achieve real-time data
The transmission is controlled by the central control room.
