Hi,
I was asked to review the loads on some supports of a GRP (Glass Reinforced Plastic) pipe, which is gravitational, performing a flexibility analysis. The support arrangement is copied from other projects, whose pipe is geometrically similar with the same service.
This pipe feeds a tank of GRP material and according to the engineering drawing there is an anchor type support positioned one meter from the tank nozzle, with elevation of half a meter from floor level.
I have no experience in the design of line support that feeds a GRP tank, but personally I would not place an anchor so close to the nozzle of a tank (much less if this tank it is made of GRP material). According to those who have been working for years in this company, there are already other projects that have done this.
Finally I would like to recommend another type of support, but as I explained, I have no experience in designing support for a grp tank.
Please help me if you have experience in this type of design. I add a drawing (Fig. N°1) showing the pipe entering the tank with dimensions in milimeters.
The information to consider is as follows:
The pipe is gravity, diam. = 24 [inch] with an equivalent static head of 30 kPa.
S.G: fluid : 1.23
Temperatures:
-T° fluid : 61 °F
-T° min ambient= 14 ° F
-T° max ambient= 89.6 ° F
-T° installation= 50° F
Thanks in advance.
