Tube heat exchangers are constructed from an array of tube which are welded or bolted into a compact bundle within a shell. The tubes are then expanded and welded into tube plates, which in turn are welded into the shell.
Most Hipex tube heat exchangers utilise fully welded tubes and shells to reduce gasket maintenance and create a tube path that is more suited for use with food.
Smaller units commonly have corrugated shells, with units that have a diameter exceeding 150mm featuring a plain shell.
These tube heat exchangers can be used as:
- steam heaters; or
- as direct expansion units using refrigeration.
Tube plates are constructed in a wide range of sizes and for different types of terminations. Hipex uses NC, computer controlled equipment to quickly and accurately produce tube plates that are specifically designed for a particular application.
