High Frequency Welded Pipe Unit: Feed steel strip of a certain specification into the machine and then use forming roll to crimp the steel strip into pipe-blank. Then under skin effect and proximity effect of high frequency electric current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe and heat up the pipe profile fringe quickly to the welding temperature and finish welding under the pressure of the squeeze roller. After cooling, sizing and broad straightening, you can get the steel pipe of needed specification. Our products such as roll forming unit,forming unit, cage forming unit can produce X80 and J55 API petroleum casing pipe and petroleum and gas pipe, which conform to the standard of API-5L,API-5CT. This unit can also produce special pipes for air cooling condenser used by electric power plant or steel mill.
