Intermediate frequency expanding machine is important in the field of hydraulic press and press pipe fitting equipment, is used for seamless steel tube expanding tube or other alloy steel, stainless steel tube expanding effect, that is, the small diameter steel pipe will be in the form of a medium frequency induction heating thermal expansion into the customer required a certain large caliber pipe, using medium frequency expanding machine after expanding tube wall thickness will not produce too big change, this is also one of the advantages of medium frequency expanding machine, and intermediate frequency expanding machine automatic constant temperature system can reduce the steel tube defects and quality problem appeared in the process of hole enlargement.

 

Intermediate frequency tube expander has made great contribution to national steel pipe industry and related energy industry, and its application field is also quite extensive. The following is its application

 

1. Construction: most underground pipeline transportation, groundwater extraction during building construction, boiler hot water transportation, etc.

2, mechanical processing category: bearing sleeve, processing machinery parts.

3, electrical: gas transmission, water power generation fluid pipeline.
