24" FRP line
24" FRP line
(OP)
We design a 24" pipe line for flue gas running on over 3.5 km of land.
Are the expension joints preferred over the bell/spigot (O-ring) connections?
If YES or NO could you, please, give reason.
Thank you all!

As mention previously I will appreciate your help if anybody has any experience with the expension joints preferred over the bell/spigot (O-ring) connections or viceversa?
Thank you!
RE: 24" FRP line
If such a thing exists, I could sell a bunch. Who makes it?
What rubber compound is used for the o-rings?
What do you mean when you say 'expansion joints'? Straub clamps? Silicone hose? Silicone hump hose? Metal bellows?

The pipe joints sound like the kind used with water pipe- either Dresser(TM) couplings (ie, flex couplings) or bell-and-spigot joint as used with DI and PVC piping. But I'm not familiar with elevated temperature or FRP applications.

I confirm that this is FRP pipe with 24"dia, that could be used in continuous service under 350 deg.F for flue gas. I do not know how other medium could be handled.
The manufacturer is in Nova Scotia, Canada.
Thank you for your input.
RE: 24" FRP line
Okay, maybe there's another more heat resistant product from them or some other frp pipe house in Nova Scotia.
Or, maybe you've been speaking with someone who really, really, really, wants to make a big sale, and may have no qualifications beyond a positive mental attitude.
When you say 'I confirm', do you mean that you have in your possession a detailed factual assertion in print, signed by an officer of the pipe manufacturer?
Even if you do, given the temperature and the pressure, I'd suggest that you ask the pipe manufacturer to recommend a joining method, in writing, and that you follow it, to the letter.
