Integrity Testing of Underground RTRP Piping

[mbk899]

Oily water drain system of the existing gas compression plant is of RTRP. Recently multiple failures were reported from the underground portion of the piping. The underground network does not have any isolation valves and has so many lateral connections. Is there any NDT method available to test the integrity of the RTRP piping network.
Thanks,

Assume by RTRP you mean GRP / Fibreglass pipe?
What do you mean by "failure"? How do you know?

Asnwer is no. There is no NDT available for this type of pipe.

It is good pipe when used AND installed correctly, but a complete waste of money if the contractor just threw it in. It is very sensitive to bad handling and poor installation and damages very easily, especially when buried.

Abandon it now and get ready to dig it all up and replace it with PE or something a lot more forgiving than RTRP.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Thanks.

Yes, it is GRP. I am more comfortable with the term 'RTRP' Reinforced Thermosetting Resin Pipe.
The failure happened in a gas compression plant while draining condensate. The joint gave away. We fixed that leakage and the plant restarted again. However, we are not sure of the integrity of the network. The entire drain system within the plant is of RTRP. While searching on the internet, I came across a standard ASTM E 1118; acoustic emission testing of RTRP pipes. I am not sure about the testing methods, accuracy, applicability for underground piping etc.
Hoping to receive more responses.
