Cermaic Pad Preheater Elements

SKU: Ceramic Pad Preheater Elements

The ceramic pad preheater element is suitable for preheating and hydrogen diffusion heat treatments associated with the welding process. In view of the flexibility of the heater they can be applied to curved or flat surfaces. The are ideal for the preheating  of pipework or vessel longitudinal and circumferential weld seams and a wide range of fabricated components. Their design is modular allowing for multiple configurations and can be connected in parallel for accurate temperature input and control.

The design of each CPP is based on a cermaic pad manufactured from sintered high alumina ceramic beads with a nickel-chromium flexible core wire serpentined within the beads. The ceramic pad is mounted directly on to a safe Superwool insulation backing which is housed in a stainless steel mesh. The pad/insulation assembly is, in turn, protected with a flexible stainless steel backing. The backing permits the efficient application of the heater to the metal surface using magnetic fixings or by banding.
