All welded plate and frame type heat exchanger optimized sealing solutions

All welded plate and frame type heat exchanger of the seal and optimization scheme improve the sealing performance of all welded plate and frame type heat exchanger, the need to choose the plate and frame type sealing material of the whole welding heat exchanger. All welded plate and frame type heat exchanger of the sealing material basically has two kinds, one kind is metal winding gasket, the other is a wave of tooth composite gasket. These two kinds of stiffness and strength of the gasket is better than that of asbestos gaskets, can effectively reduce the deformation rate of gasket, sealing ascend all welded plate and frame type heat exchanger.
