Air Pressure in a PVC pipe

[prmmel]

I have a project where we will be injecting air into approximately 1000 2" sch 40 PVC well points. The wellheads will have approximately 5 - 12 psig applied . Each well head will need a flow measurement device, so we will manufacture an orifice plate to read flow. Our preference is to build the well head device out of 2" sch 80 PVC pipe which will consist of ~ 36" sch 80 pipe, a 2" tee, a 2" pvc gate valve, a 45 and ~ 6' of 2" flexible pvc tubing. Our concern now is that PVC pipe can explode with air pressure. The limited potential of a maximum of 15psig is of concern to us. We wanted to know how others would view this. Air temp in the pipe will be ~70-80F.

An question would be - will this pipe have sunlight striking it.

I depending on temperature variations and sunlight I would have no issue with 15psig in sched 80. There could certainly be code issues involved though.

Yes, the pipe is exposed the sunlight. That is one of the reasons we went with the UV resistant Sch 80 PVC. Actual operating pressure will be typically 8psig. The 15 was an extreme possibility. We are trying to check on code issues, but wanted others take on the minute pressure.

Call the mfg??

prmmel; You have actually asked this in an entirely inappropriate forum. You should ask again in a forum where piping is discussed.

Ask it in: forum378
