Advantages of HFW steel pipe

Straight seam high-frequency resistance welded steel pipes have been continuously improved due to technological advancement in the past ten years, so that their application range has been rapidly expanded. Its main advantages are:

a. 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 welded seam has been correspondingly improved during the tube making process.

b. In recent years, due to the advancement of automation technology, the main parameters of resistance welding can be optimized by computer control, so that the quality of welding is greatly improved and guaranteed.

c. Straight seam high-frequency resistance welded steel pipe has small residual stress and high strength.

d. The geometric precision of straight seam high-frequency resistance welded steel pipe is high, which is convenient for on-site installation, butt joint welding and anti-corrosion construction.

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

f. 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 insufficient quality of the weld seam of the straight seam high-frequency resistance welded steel pipe, external anti-corrosion treatment is required.
