Coil Failures Pt. 7: Fabrication of Hardening Inductors

August 2nd, 2010 : Posted in Induction Hardening, Induction Heating, Long Lasting Inductors : 0 Comments   

If the induction coil contains numerous brazed joints and, in particular, if there are 90° joints, then water flow in cooling coil turns could be impeded. This problem is more likely to occur if small diameter tubing is used for coil fabrication. As a result, booster pumps may be needed to provide sufficient pressure for water cooling of the coil.
