Description

Black Gas Field ASTM A53 ERW Carbon Steel Welded Pipe

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels. HFW is a solid resistance heat energy. The high frequency current pass through the metal conductor, will produce two peculiar effects, skin effect and proximity effect. And HFW process is to use the skin effect to concentrated on steel object surface, use proximity effects to control the position and the power of the high-frequency electric current flow path. Since the speed is very high, the contacted plate edge could be heated and melted in shore time, then extruded through docking process.

When choosing the type of the ERW pipe, it is equally important to consider not only its main characteristics but also the type of medium that will be transported through them (liquid or gaseous), as well as the degree of its aggression. These factors influence the choice of pipe products in terms of the composition and, accordingly, the properties of the material that was used for their manufacture.
