In modern construction engineering, municipal pipe network and energy projects, the requirement for steel pipes is not only "usable", but "efficient, reliable, compressive and durable". Among many steel pipe types, high-frequency welded pipe and submerged arc welded pipe have become the first choice for engineering construction because of their excellent performance, flexible adaptability and high cost performance.

In a word, their advantages are: fast forming, stable welding and strong performance. So how exactly are they welded? What are the technological characteristics? In what fields is it applicable? Let's take you to know more!

Welding principle-heating the edge of steel strip by "high frequency current"

High-frequency welded pipe is to apply high-frequency current to the edge of steel strip, so that it can be quickly heated to a molten state, and then the edges of steel strip heated on both sides are quickly butt welded together with the help of extrusion rollers.

The whole process does not need covered electrode and flux, and it is an induction heating welding technology without melting filler, so the efficiency is extremely high.
