Following checks are made during the course of erection of condenser.
- Welding checks as per welding manual consist of welder test, consumables selection and processes as per OEM. This is very relevant as condenser is having huge quantity of welding jobs at different stages of erection. Therefore all the details of welding specially sequence of welding is very important or there will be distortion in forming the box. OEM specify the sequence in their manual.
- Level Position of hot well w.r.t. Transverse and longitudinal axes of turbine as well as front & rear water box ends of condenser and Bottom plate openings and alignment of bottom plates w.r.t. to Turbine axis.
- Level and alignment of bottom plate relative to turbine axes within ½ degree slope.
-Sag checking of tube plates and also flange checking of water box and chamber.
-Length in between Tube Plate at locations, covering full area of tube plates.
-Distance between sidewalls and height & verticality of Sidewalls.
- Position of Support Plates. Hole alignment of tube plates and tube support plates.
- Verticality of hinge door assembly. Tolerence should be as per drawing.
- Verticality of hinge door assembly.
Location of spring units and setting of condenser slope.
Alignment of L.P Cylinder opening with Condenser.
-Dimensions of the dome walls from turbine longitudinal and transverse axes.
-Nozzle orientations as per drawing.
-Orientation of condensate spray nozzle.
-Check position, level and alignment of heater.
- Mock up test on separate tube plate including air leak test on mock up set up.
- Setting of expander for required tube thinning as per the procedure given by OEM.
