PWHT alumina ceramic beads,technical ceramic, Flexible Ceramic Pad Heater

All flexible ceramic pad heaters are constructed of 80/20 Nickel / Chrome Multi- strand wire, insulated with inter-locking sintered alumina pink ceramic beads, nickel 212 cold tail (tigged) and two male 60 amp twist locks complete with insulated covers.

Available in numerous sizes and ratings, they can be used up to 2150F / 1176 C in various heating applications.

Application:

This special sintered alumina ceramic beads as components of ceramic pad and channel heaters can be used for pre and post-heaters welding applications because of its excellent heat resistance.
