SURFACE TYPES

PILLOW PLATES

THERMAPLATE pillow plates surfaces are a fully welded and inflated type heat exchangers that are manufactured by stacking two flat sheets of material and fuse welding them together with a strategically positioned welding pattern.

A typical welding THERMAPLATE pattern comprises of an outer seam weld defining the total pressure boundary of the plate and then an interior circle weld pattern specifically configured for the service type and performance requirements for a given application.

Once the welding is complete, the THERMAPLATE pillow plate will then be expanded by pressurizing the space between the two sheets. As pressure is increased, the gap between the unsupported portions of the plates will increase, creating the identifying “pillow” shaping of the plate.

        RESISTANCE WELDED vs LASER WELDED

        What’s the difference?

        Both methods produce very similar looking pillow plate surfaces, but there are different advantages between the two options. We manufacture using both methods and we are happy to assist in selecting the best method for your application.

        Both methods produce a high-quality product that is ASME Certified and can be provided in a wide range of operating temperatures and pressures.
