High Frequency Welded Tube Mill Line Hg508

These High Frequency Welded Tube Mill Line HG508 is designed to produce welded pipes of 219mm-508mm in OD and 6mm-18mm in wall thickness.
The specific process flow is:
Steel strips are first fed into the machine then are shaped into pipe blanks by rollers.
Then, under skin and proximity effects of high frequency electric current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe.
The heated up pipe profile fringe is quickly moved to the welding temperature and finished welding under the squeeze roller's pressure.
After cooling, sizing and broad straightening, the steel pipe of needed specification is achieved.
Our products such as roll forming unit, FFX forming unit, cage forming unit can produce X80 and J55 API petroleum casing pipes and petroleum and gas pipes, 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 plants or steel mills.
