Glue or gasketed?

For those of you who install large diameter pipe (4"-6") which do you use and why? I am bidding a job for an organic farm that needs a few thousand feet of mainline installed to run their rain reels with. They have a tractor driven well capable of 500 gpm @ 150 psi.

I would recommend gasketed pipe for anything over 3" with thrust blocks and/or restraints.

I don't think glued fittings will hold @ 150 PSI;

Maximum operating pressure for 6" SCD 40 PVC is 106 lbs, 133PSI for 4", bursting pressure is higher.

I would go for gasketed pipe with thrust blocks and/or restraints like the irrigator suggested, or flanged fittings.

PVC vs. HDPE.
I'm too medicated to comment much.
If I were to go with PVC at that size it certainly would be gasketed.

My rule of thumb, anything over 2.5" should be gasket.

Dealing with this flow and pressure is a different "ballgame" then residential or light commercial work. There is definately a learning curve. It might be a good idea to see if you can work with someone who has done this type of work before, you will avoid any costly and embarassing mistakes and learn along the way. Just my two cents.

On pipe that size, gasketed is the way, the truth and the no leak. Come-alongs and a beefy crew are needed.
