3. TURBINE COUPLING – PRESSURE TUBING (Valve-Coupling Dresser)
The joining of the Turbine to the pressure tubing is done via a coupling of expansion
(coupling dresser) for two reasons:
• For easy placement or removal or the turbine.
• To allow for the expansions due to temperature changes.
The coupling dresser, as well, allows small misalignments that could exist between the
turbine and the pressure tubing.
