HFW Steel Pipe

Description:

The appearance is smooth, high precision, low cost and low weld seam height, which is beneficial to the coating of 3PE anti-corrosion coating. The welding methods of high-frequency welded steel pipes and submerged arc welded pipes are significantly different. Since welding is completed instantly at high speed, the difficulty of ensuring welding quality is much higher than that of submerged arc welding.

Applications: 

Mainly used for the transportation of media such as land, ocean oil and gas, coal slurry, ore slurry, and pipes for offshore platforms, power stations, chemical industry and urban building structures
