Intermediate frequency induction tube expanding machine

Thermally expanding and drawing type tube expander USES steel tube with strong shrinkage to enlarge diameter. Seamless steel tube is a kind of thermally expanding tube.A process of expanding pipes by means of medium frequency induction at high temperature to enlarge the diameter of pipes.

Drawing type expanding machine itself belongs to the non-standard product, according to customer requirements to develop a special model of seamless tube, and the labor cost, raw material tube blank cost are relatively low, high production efficiency, is the current international and domestic expanding machine hydraulic field development trend.Pull-type tube expander integrates hydraulic technology and medium frequency induction heating technology.

In the production of seamless steel tube diameter enlargement into large diameter steel tube because of the production capacity of the medium frequency tube expander can not process too large diameter tube, we need to process the small diameter tube and then use the method of thermal expansion in the processing of the production of seamless steel tube.
