I was recently building a greenhouse in my back yard using 3/4 PVC pipe. I had noticed that there was no way (that I could find) to provide a hinge for doors, windows and access panels. So I designed one. I suppose if you want to have this for different PVC pipe. You could scale it. Since there are some variance in different manufacturers. the design is meant for pipe with an O.D. os 1.05 inches, thus the I.D. if this is 1.1 - - so this may fit losely
