Loads on secondary pipe supports.

Loads on secondary pipe supports.

Loads on secondary pipe supports.

(OP)
Is there any thumb rule, guide line, notings available for calculating the pipe loads on secondary pipe supports (like cantilever brackets, inverted L suppoets, Inverted goal post supports) so that it is sure that the members used for such a supports are safe for such loads (because in the load limits for such supports which are mentioned in the support spec are only on the papers)

RE: Loads on secondary pipe supports.

Either the specific loads from the designed pipes filled with fluid or fifty pounds per square foot for future pipe additions.

RE: Loads on secondary pipe supports.

(OP)
For pipe loads i.e. dead wt loads which includs fluid plus insulation plus thermal stresses due to temp. and not for future loads

RE: Loads on secondary pipe supports.

Engineering companies specializing in refinery design use structural design principles and methods as found in the AISC Steel Design and ACI Concrete Design manuals for both primary (pipe supports and pipe racks) and secondary supports (brackets, tee supports and miscelaneous pipe supports).

"Pumping accounts for 20% of the world's energy used by electric motors and 25% to 50% of the total electrical energy usage in certain industrial facilities." - DOE statistic  (Note: Make that 99.99% for pipeline companies) http://virtualpipeline.spaces.live.com/

Dead weight does NOT include contained fluid weight - contained fluid weight is live weight (look t at B31.3).  Dead weight AND live weight combined is called (just) WEIGHT.  This nonsense of referring to all weight as "dead weight" seems to have started in the nuclear business in the 1970's (another example is their calling computer programs "codes") and now the young people coming into piping engineering are blindly following that error.  Enough already!!

The olde guy now folds his soap box and steals away for his afternoon nap.
