Usage of High Frequency Welded Pipe

The use of high frequency welded pipe is welded pipe. The straight high frequency welded pipe has the characteristics of relatively simple process and rapid continuous production. It is widely used in civil construction, petrochemical, light industry and other departments. It is mainly used for conveying low-pressure fluid or making various engineering components and light industrial products.

 

High frequency welding is based on the principle of electromagnetic induction and skin effect, proximity effect and eddy current heat effect of alternating current charge in conductor, so that the steel at the edge of the weld can be heated locally to the melting state, and the butt weld can be joined indirectly by the extrusion of rollers, so as to achieve the purpose of weld welding. High frequency welding is a kind of induction welding (or pressure contact welding). It has many advantages, such as no welding filler, no welding spatter, narrow welding heat affected zone, beautiful welding shape, good welding mechanical properties, etc. Therefore, it is widely used in the production of steel pipe.
