Advantages of ERW steel pipe

1. Straight seam high-frequency resistance welded steel pipe does not add any chemical components during welding, and its welding quality mainly depends on the quality of the base material. In recent years, due to the continuous improvement of the quality of hot-rolled coils, the quality of the weld seam has also been correspondingly improved during the tube making process.

 

2. Due to the advancement of automation technology, the main parameters of resistance welding can be optimized by computer control. The substantial improvement of welding quality is guaranteed.

 

3. Straight seam high frequency resistance welded steel pipe has small residual stress.

 

4. Straight seam high-frequency resistance welded steel pipe has high geometric size accuracy, which is convenient for on-site installation, butt joint welding and anti-corrosion construction.

 

5. The short bead of the straight seam high frequency resistance welded steel pipe means that the reliability is improved.

 

6. Straight seam high frequency resistance welded steel pipe has a price advantage, its price is much lower than the price of straight seam double-sided submerged arc welded steel pipe. However, due to the lack of weld seam quality of straight seam high-frequency resistance welded steel pipes, external anti-corrosion treatment is required.
