Hi Pipers
How do I install temperature and pressure instruments in GRP / FRP pipes ?
Please share your experience with theoretically and practically insight.

One way to do this is to install an GRP/FRP flanged joint and a "Bleed Ring" (with a tapped outlet) for the instrument, vent, drain, etc.

Hi skgarg,
Another way half pipe saddles with stainless steel thread bushing

I've used FRP threaded saddles for instrument connections, check this link out ...drop down to sheet 8 for threaded saddles.

For a more corrosive service, our project opted for a complete reducing tee, nipple and flange arrangement for all instruments, as well as drains, on FRP pipe (2" min branch size). I have also used bleed rings and this method is definitely a space/ cost saver compared to the previous.
