Steel Pipe supprtr analysis
Steel Pipe supprtr analysis
(OP)
Hi, i am trying to design a support system for a DI pipe. The system is basically a "U" shape strap over the pipe and the strap is fixed to a support base. I have been able to obtain the forces due to water moving in the pipe (along the pipe & perpendicular to it) and assumed that they act through the pipe center line. However I and some colleagues are having difficulty in understanding how to transfer (or how it tranfers) the perpendicular force (230kN) to our support base and what stresses it causes in the strap by forcing the pipe to move/roll. Please see diagram. We have assumed that the longitudinal force (180kN) will cause a shear and tension on the support bolts due to their eccentricity
PS I am UK/Ireland region based but saw the idea from a US company's web-site. However I am struggling to find some UK/Ireland based standard information. Therefore any suggestions on these types of products would be greatly appreciated. Thanks :)

If the joints are flanged or otherwise restrained, all the forces resolve themselves through the lengtrh of the pipe and there's no thrust at the elbow.

I would expect something like a cross between:

With the bottom of the steel on the concrete.

Timing has a lot to do with the outcome of a rain dance.
RE: Steel Pipe supprtr analysis
The forces were based on 10 bar pressure and a 45 degrees bend, the resultants were taken from a table from a CIRIA report on thrust blocks for pipes
If I removed the gap (and also there are no other forces than those due to the waterr in the pipe) what other variables would there be? I could make some assumptions.Is the analysis any easier or would i be wasting my time without software?
