Storm drain Pipes

Storm drain Pipes

Storm drain Pipes

I was hoping someone could tell me what is the max. deflection angle that a stormdrain pipe can be lenght wise and also how long do they typically come in.


RE: Storm drain Pipes

varies greatly, and depends on the type of pipe.  Generally not more than a few degrees of deflection per joint.  you should call a manufacturer of the particular type of pipe that you intend to use and get the answer from them.

RE: Storm drain Pipes

You can buy bends for RCP. I think they are 7.5 degrees. if you start out deflecting joints you will not learn to layout storm drains properly. Use the bends.

RE: Storm drain Pipes

If reinf. conc. pipe, the manufacturer can tell you how much deflection you can get with his pipe. A 24" RCP can be laid with a 140' radius. If you use radius pipe, it may be as small as a 65' radius. If you use a "pulled" radius pipe, 40'

Get a catalog from Hanson pipe. It has all the info.


RE: Storm drain Pipes

You can always cut RC pipes and put two ends together using a concrete pipe collar.  Typically I do not exceed 45 degrees when doing this.  As long as your increased head loss does not blow out your system's hydraulics, it should be fine.
