Equipment Condition:
TWPS in Standby Shutdown with Drain-Down
Replace a pipe coupling (see Figure 17).
1. Make sure the TWPS is in Standby Shutdown with Drain-Down. Refer to WP 0017.
2. Remove the pipe coupling as follows:
a. Remove the nuts and bolts that secure the clamps to the pipe joint at both ends of the
pipe joint. Remove the clamps and set aside.
b. With a screw driver and hammer, tap the gasket retainers loose from the gaskets at both
ends. Push the pipe joint and gasket back onto one of the pipes until it clears the end of
the other pipe.
c. Remove pipe support clamps and loosen other connections as needed to free one or
both pipes to move or rotate enough to move the ends clear of each other. Remove the
gaskets, gasket retainers and pipe joint from the pipes.
