Heat Exchanger Gaskets

Simply formulating the  right gasket compound and profile for a specific duty is an art – or more  accurately – a science in itself. To compound the right rubber mixture can involve the selection of anywhere from five to fifteen different substances from around 1700 of different    grades of polymer,vulcanising chemicals and processing materials currently available. And  that selection process is, itself, influenced by a host of other parameters that could affect the eventual performance of the gasket.
The working environment, the service temperature and pressure, the actual nature of the duty and the interreaction between the gasket material and the plates all,individually and collectively, help to determine the final choice of materials used.
The gasket is moulded in one piece. The material is normally an elastomer, selected to suit the actual combination of temperature, chemical environment and possible other conditions to be considered. The one-piece gasket is consist of one field gasket, two ring gaskets and links.
