The special feature of this ferrite rod is that its deep groove allows for optimal cooling of the entire core.

The rod is constructed of ferrite material and is a important
accessory for use in high frequency welding of tubes and pipes. It could offer a ideal
magnetic path even with a high temperature.

High Frequency Induction welding is the common process for steel tube manufacturing. Ferrite rod core plays a very crucial part in increasing the efficiency of welding process. Major requirement of ferrite cores are low power loss and close control of dimensions.

This kind of products is famous for a
service bit can be passed through the center hole, which may make insertion of the bit
difficult. This kind of rods could save energy and improve the whole process efficiency.
