Hollow fluted Impeder Cores Ferrite Rods CRSH 55×27×200mm soft magnetic material for Tube Welding of High Frequency Induction Increasing The Efficiency of Welding Process straight seam welded pipe Production Line 
Ferrite Impeder Rods for tube welding:
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.
Impeder rods are manufactured using soft ferrites by extrusion and sintering process.  impeder rods are manufactured under controlled processes to achieve the tight dimensional control and highest magnetic properties, which would ensure the best perbance of steel tube welding.
We offer complete range of products in all kinds of sizes and shapes. such as 5×1.5× 200mm.6×2× 200mm.8×3×200mm 9×3×200mm,10×3×200mm,20×6×200mm,
30 ×15×200mm, 50×25×200mm,80×40×200mm.....
Ferrite high Grades:
 we,Beijing CSTS technology Co.,Ltd manufacture impeder rod cores for induction welding with low power loss material grades,  provide better magnetic such as lower power loss, higher saturation flux density (Bs) as well as better Bs stability at higher temperatures.
CRSH 55 ×27×200 hollow fluted with grooves type
Features: It is a radial groove type with a central hole, and cooling water can be injected into the inner diameter part, which can effectively cool the entire magnetic core.
In addition, the holder rod can be inserted into the inner diameter.
