Technical principles, applications and development trends of high-frequency welded pipe units
High-frequency pipe welding unit is an environmentally friendly metal pipe welding equipment, which is widely used
in construction, petroleum, chemical industry, light industry, automobile and other fields. This article will introduce in
detail the technical principles, applications and development trends of high-frequency welded pipe units.
1. Technical principles
The high-frequency pipe welding unit uses the skin effect and adjacent effect of high-frequency current to quickly
heat the ends of the pipes to be welded to a molten state, and then applies a certain pressure to connect the pipes
together. The core of the high-frequency welded pipe unit is a high-frequency power supply. When the
high-frequency current it generates passes through the pipe, due to the skin effect, the current is concentrated in a
thin layer on the surface of the pipe, causing the end of the pipe to rapidly heat. At the same time, the adjacent
effect causes the current to form a strong magnetic field at the end of the pipe, creating a strong attraction and
bringing the pipes into close contact, which is beneficial to the welding process.
2. Application
High-frequency welded pipe units have the advantages of environmental protection and energy saving, and are
widely used in the following fields:
Construction industry: Steel pipes of various specifications produced by high-frequency welded pipe units can be
used for support, hoisting, grids, etc. of building structures, such as scaffolding pipes, buckle-type scaffolding, etc.
Petrochemical industry: The oil and gas transmission pipelines, chemical pipelines, etc. produced by
high-frequency welded pipe units are widely used in petroleum, chemical industry and other fields.
Light industry: Various lightweight metal pipes produced by high-frequency welded pipe units, such as
aluminum-plastic composite pipes, aluminum foil hoses, etc., are widely used in packaging, beverages, cosmetics
and other fields.
Automotive industry: High-frequency pipe welding units produce automotive pipes, such as brake oil pipes, fuel
pipes, etc., which improve the safety and reliability of automobiles.
Other industries: In addition to the above fields, high-frequency welded pipe units are also widely used in electric
power, communications, agricultural irrigation and other fields.
