Hi,

I am doing Static analysis for 20” Pipe line with 35°C as temp running from Tank yard to Jetty with some part going underground.

Please find attached simplified overview….at Point B at first tank nozzle we are considering water hammer to happen.

Do we need to consider total length from point A at Jetty to point B tank nozzle in my force calculation??

What I am worried about is will the hammer effect last long up to Jetty or I need to consider up to underground piping ?

Please give your expert comments as soon as possible

Thanks & Regards
Nilesh

Just put a beefy stop in the middle of your 80 meter run right before point B, and put some occasional forces at your first four or so elbows to check the occasional stresses. I am sure there is some calculators to come up with a shock load value, based on flow rate and how fast you close that valve at B, but I would only consider loads from B to where it goes underground, just as a sanity check.
