How much PSI into PVC pipe?

Question

How much PSI can you put into two 3" x 3' PVC pipes connected by a 3" PVC Tee?

Answer 1

I have no idea!!!!

Please answer my question if it applies 2 u?   THx

Answer 2

This may help!

Size is not the issue.  The PN rating is more important.  Each PN is rated to a certain pressure.  You really need to know your flow rates through the pipe.  ie how much water do you need?  The TEE is a PN 18.  Just need to conver MPA to PSI

Answer 3

We have hydrostatically tested PVC pipe to withstand a pressure of 50 psig.

Answer 4

Depends greatly on the temperature.

PVC does poorly if the temp goes beyond 90-100F.

Answer 5

It depends on the pipe manufacturer , because they produce different pressure tolerable pipe of same size. I mean a 3"x3" pipe can tolerate different pressure depending on the pipe material . It is fixed by the manufacturer.

Answer 6

Thickness iis an indicator. You need to ask your supplier.The adhesive/joins are an important factor too.
