anchor forces on long straight pipe

[swoosh172]

I have a 6000 foot above grade crossing for a new water line on a steel bridge. Due to tight constraints and aesthetics we are using bellows type joints. The pipe is 8 inches in diameter and is at 150 psi. I am wondering what the anchor forces will be if I have 2,000 feet between anchors with the expansion joint in the center. I have the force of the joint which is 12,000 pounds. To guide the pipe we are looking at pipe slides every 45 feet to act as a guide and a support in one. Roller supports will be used every 15 feet otherwise. The guides are PTFE. The water is at maybe 60 degrees. Do I need to account for the friction force of the pipe and the slides in the anchor load calculation, or is the temperature and pressure low enough that it is negligible? I don't have a modeling program to help.

Thanks for the help!

Did you consider 8in ductile iron water pipe for this application? Rigid mechanically locked joints in series with your thermal expansion coupling(s) as previously discussed.

====R====R====R====R====EEEE====R====R====R====R====

R-Rigid Mechanical Joint
EEEE- Expansion Coupling

Steer clear of frictional DIP restraints. Stick with rigid factory welded restrained joints. Just a thought.
