Non-destructive testing of water and sewer force mains
Non-destructive testing of water and sewer force mains
(OP)
Frequent listener first time caller...
Does anyone know of any NDT technologies for inspecting ACP/PVC water or sewer force mains that don't require bypassing? I'm aware of acoustic methods for DI and CI but I can't seem to find anything for non-ferrous pipes.
All commments/suggestions are appreciated.

Finally, as various soil conditions and/or contamination can degrade both types of pipes you talk about e.g. from the outside, perhaps you could consider some physical potholing or other daylighting to examine/peck on? outside wall conditions in areas? I would however caution that these kinds of pipes can be hard to locate, and perhaps particularly even dangerous/vulnerable to excavate/work around for this and other reasons, and of course all utility and OSHA rules etc. should be complied with in this regard.

dicksewerrat, we were looking into Sahara and Smartball, which can inspect pressure pipes while in service (w/out bypassing or dewatering) but the examples I've found only seem to refer to DI/CI pipe.
Thanks for your comments though. From my conversations with operators/utilities, no-one even bothers to inspect unless there's a major failure and that's what we're trying to avoid.
