Note! In applications of heating up the water by steam, the care of the right timely and slowly way of working of the steam valve shall be taken care of in order to avoid the corrosion of chloride salts at excessive high temperatures. To promote that purpose, it is useful to arrange continuous flow of the water through the heat exchanger. In excessive conditions the better corrosion sustaining material than AISI316L can be chosen.

A structure for the end of pressure vessels, most applicably plate heat exchangers, for reducing the effects of movement changes and vibrations caused by variations in internal pressure and temperature. The end is made up of a heat transfer plate and an end part in such a way that the end part is connected by welding to the shell of the outer surface of the heat exchanger stack, forming an enclosed chamber on the end of the heat exchanger, into which chamber higher pressure than the external pressure level is brought and/or generated. The higher pressure receives and dampens, via a heat transfer plate, vibration and pressure shocks harmful to the heat exchanger structure in the medium circuits of the heat exchanger.
