Thanks for info. As mentioned, do you have any data for the failure of the Pipe Supports. If you have, kindly send the same to undersigned. I would be very much grateful of you.

Don't forget to take into account the tremendous thrust induced into the pipes where bends occur (whenever the flow is interrupted or at the startup of the system.  These forces will govern your design in most cases.) I am assuming your pipes will be carrying fluids. Also, do not FIX your pipeline to the pipe supports unless you have designed for these forces. I have seen many pipe support structural failures due to the pipeline being fixed to the support where the thrust forces were (apparently) not taken into account.

Bhavin,

Other than possibly some P-Delta effects on your pipe support the limiting drift is generally a requirement of the piping system.  If this is primarily a straight run pipe it may not be a big issue, however, if the pipe turns down and connects to a piece of equipment ( i.e. pump, compressor, etc.) then you may be introducing excessive loads into the pipe flange connection.  You should seek drift limits from whoever is designing the piping system.

Pipe Supports (Tee type)





Dear all,

This is regarding design of Pipe Stanchions (Steel structure)
supporting heavy pipes at certain elevations.

                For supporting the individual pipes, generally Tee type (cantilever
column) of Pipe Stanchions are used. As the stanchions are flexible in
both the directions, lateral deflection at the top of the stanchion
may be quite high as compared to the pipe displacement. Hence, are
there any limits or general guidelines (say above 7.0m) that above the
particular height Frame type of stanchion should be used.

Thanks,

Bhavin Shah
