High Pressure Pipe - Clear Section
High Pressure Pipe - Clear Section
(OP)
I was wondering if anybody is aware of an engineered high pressure clear pipe option that is rated higher than typical clear PVC pipe/fittings or full-view sight flow indicators. A portion of the pipe length can be metal, and then if there is a clear section within it, that is what is desired. The higher the pressure the better, but I will consider all ideas out there to see what are the best options.
The full-view, sight flow indicators that I've seen are only rated to about 150 psi at 2" diameter.
I am basically wondering if there is technology similar to a full-view sight flow indicator (or something different) but with higher pressure rating.
Thank you!

Is a magnetic levelindicator not good?

Thank you LittleInch. Could you please share the details of where you got this built and what diameter it was?

You just need to start looking for suppliers of clear acrylic or perspex - maybe look or ask around for submarine or view port plates for pools.
There is nothing at any decent pressure rating available off the shelf and often the issue is how do you join it or compress it between flanges without it breaking or leaking.
Talk to some sigh glass manufacturers and see if they have ever made a "special". It needs dialogue, not web pages or e-mail.

A "bullseye" sight glass arrangement will allow you to look through a sample, and such arrangements can be bought for pressures a heck of a lot higher than 150 psig, but a "bullseye" isn't simply a clear round section of pipe. You can buy 2" NPS plug type fused glass sight glasses from McMaster Carr good for 500 psig and put them on opposite sides of a 2" 3000# threaded tee and get a close approximation of a "bullseye" sight glass for very little money. Be careful though if the product is hazardous or the temperature is significantly above ambient.
A "full view" flow-through sight glass, more or less a clear section of pipe, is going to be hard pressed to go beyond 150 psig, especially if you need to go to larger diameter than about 2" NPS and the temperature is significantly above ambient. Remember that the safe allowable stress factor for brittle materials is in excess of 10x, and all the transparent materials- including acrylic and polycarbonate and even your transparent PVC- are relatively brittle and subject to brittle fracture.

Just thinking out loud...
I've made vessels out of acrylic before, but we only went up to 100 psig. I'm sure they can go higher, as LittleInch mentioned.
