Abstract
A fluid testing arrangement includes an adaptor/connector 16 which couples to a service pipe 11 to allow fluid passage to continue from the main pipe 10. A catheter 18 is passed through the supplementary connection 17 and through the bore of the adaptor into the service pipe 11 until it reaches the main pipe tee connector 12. A logger 20 senses and measures the fluid pressure in effect, at the main pipe without the need to excavate.
Claims15
Apparatus for providing remote testing of fluid pressure within a main pipe, said apparatus comprising
- coupling means for coupling a pressure testing device to an auxiliary pipe having a bore therethrough and connected to the main pipe, and
- elongate flexible fluid bore means for providing an independent passage between the coupling means and the main pipe via the bore of the auxiliary pipe to provide a fluid pressure sensing path adjacent the main pipe to detect main pipe fluid pressure.
A method for remote testing of fluid pressure within a main pipe, said method comprising the steps of
- coupling a pressure testing device to an auxiliary pipe having a bore therethrough and connected to the main pipe,
- providing an independent passage between the coupling testing device and the main pipe by utilising elongate flexible fluid bore means fed through the auxiliary pipe bore to allow fluid pressure testing of the main pipe pressure to be effected.
A pipe coupling device for insertion between two pipes and including
- a body with a bore therethrough,
- means for connecting the body with a first pipe,
- means for connecting the body to a second pipe to allow fluid flow between the first and second pipes in use, and
- catheter receiving means for receiving a catheter and configured to allow a portion of the catheter to pass into the first or second pipe through the coupling bore, in use.
