Are pipeline surge loads considered PRIMARY
Are pipeline surge loads considered PRIMARY
(OP)
Hi
Could someone let me know whether the pipeline surge loads are considred primary loads in the design of the support structure?
I am designing a bridge and a pipe trestle to an oil jetty. It is not clear in my mind that the surge loads are considered primary or secondary.
Thanks in advance.

Timing has a lot to do with the outcome of a rain dance.

Thanks a lot.
Are there any reference documents or guidelines that I can make reference to in my calculations?
If you can let me know any American/British standards or a particular document or guidelines I would be most grateful.
Kind regards

If this were the Canadian Building Code, then I'd say it qualifies as a principal load (and hence the 1.5 factor), but that the companion loads that go with it would be limited... i.e. you wouldn't use wind or seismic loads in combination with it. Therefore, I think I'd use:
1.25*DL + 1.5*Surge + 0.5*Thermal
0.9*DL + 1.5*Surge + 0.5*Thermal
Hoever, if I were to have a temperature load as my principal load, then I need to include the surge loading as a companion loading associated with it. Therefore, I'd probably also have:
1.25*DL + 1.5*Thermal + 0.5 * Surge
0.9*DL + 1.5*Thermal + 0.5 * Surge

pipe surge loads looks like pipe operating loads to me

Thank you for your response and the information.
I've been reading about the water-hammer. This makes me wonder whether depending on what the pipeline is carrying, such as high density fluids (e.g. bitumen, the effect may be different.
Any thoughts?
