Forbes Marshall Thermodynamic Trap
6.
Start-up and Commissioning:
6.1. Flushing of lines:
As part of pre-installation all fluid handling equipment particularly piping should be
thoroughly cleaned of scale and the internal debris which accumulates during construction.
This is accomplished by blowing or flushing with air, steam, water and other suitable
medium.
Follow these steps to carry out the flushing.
1. Close the upstream trap isolation valve and open the bypass isolation valve.
2. Let the condensate drain for 10-15 minute or until clear condensate starts coming out,
whichever is earlier.
3. Now slowly close the bypass isolation valve and open the upstream trap isolation valve.
Note:
For a detailed procedure on flushing of lines please visit Forbes Marshall website.
6.2. Commissioning:
After installation or maintenance ensure that the system is fully functioning by confirming
condensate is passing through it.
1. After flushing of lines is complete, ensure that bypass isolation valve is closed and
upstream trap isolation valve is opened.
2. Check for leaks and attend if any.
