6.3 Shutdown
6.3.1 Measures to be taken for shutdown
During prolonged shutdown periods, ensure that the following conditions are met:
1. Drain fluids which change their physical condition due to changes in
concentration, polymerisation, crystallisation, solidification, etc. from the piping.
2. If required, flush the piping with the valves fully opened.
6.4 Returning to service
For returning the equipment to service, observe the sections on commissioning/start-
up and the operating limits (
In addition, carry out all servicing/maintenance operations before returning the valve
to service. (
