Note:
Thermal expansion calculated with respect to fixed point of turbine as indicated in the
turbine GA with ambient temperature considered as 10°C
4. Maximum allowed external forces and moments on turbine
connections
a. The piping must be connected without pre-stress at ambient temperature by
means of fixed points, supports, springs & hangers etc adjusted in a ways
that the flanges or the weld ends are located in the specified distance and
parallelism.
b. No additional forces are allowed when
connecting the piping to the turbine.
c. Allowed F&M for each connection to be within
(0,F) to (M,0)

d. The stated forces and moments only refer to the leak proof ness of a flanged
connection with similar nominal bore and pressure stage.
e. For the turbine stability check, the actual forces and moments of the
connecting pipes have to be stated to SIEMENS Ltd.
5. Heat-loss from turbine approximately 5 kW
