Stress Relieving Interlocking Insulators for Pre and Post-Heating

In welding large structures, pipe works and reaction vessels etc. it is a common practice to locally employ electrical heating devices to raise the temperature of the metal sections prior to welding and to control the sudden fall in temperature after the area is welded.

Jyalox ceramic has excellent electrical properties such as insulation and heat dissipation which ensure safe operation, quick and proper heating of area at the elevated temperatures.

The electrical device is in the form of flexible heater mat, constructed with alumina ceramic interlocking beads. The electric heating elements are supported by ceramic beads which insulate the device from the strucutre being welded.

Flexible electrical heating mats find the widest use in stress relieving applications, as the interlocking pattern of ceramic beads allow maximum flexibility to the mat, to cover the heating element properly from exposure to the area required to be heated up, such as concave, convex and flat surfaces of vessels, pipes etc.
