Pipe line quick disconnect
Pipe line quick disconnect
(OP)
I am loking to be able to disconnect a 6" PVC pipe from its fitting inside a 'dry' manhole at both sides of the manhole, with the intention of cleaning/ tv-ing the pipe line between manholes (this is a pressure main). Instead of flanges or some other type of cumbersome and time consuming method of removing the section of pipe within the manhole, to access the line on either side, I am wondering if there isn't some sort of 'quick-disconnect' that I can use here. This cleaning will be done at least twice per year, over about 8 or 9 manholes, on an active line (obviously not when were doing this--it will be bypassed). Thank you for your help.

try this also which may be more suitable for PVC

A cleanout is a pipe that leads from the sewage system to the surface of the ground, giving you or your plumber easy access to the sewer.

Also, some type of locking cap would be a must, to prevent some poor soul from getting a bath...like on a wellhead?
Again, I've never seen it done, but I would research some existing applications first before I sealed a plan with a CO on a pressure main.

What I described as a clean-out is not a gravity connection. It is just a Y stub up to the ground surface. The proposed "clean-out" would have to be made with the same pipe materials as the force main. Probably would look somewhat similiar to a pig launcher.
Not sure what you are saying about air locks. Why would you have an air lock? The fluid would force the air through the pipe. This would be the same occurence every time the pipeline commences operations after cleanings.
Can't read too much into this as little information is known about the pumped fluid, exposure to weather, pressures, etc.
