Overpressure due to thermal expantion of a liquid in a piping.
(OP)
My issued is the following,
In a pipeline if you have two valves in both ends and these valves are closed what would happend if the radiation of the sun hit the pipeline all the day.....what is the maximum pressure that can rise up the pipeline......

The rule of thumb is that if equipment is operating full of liquid, the equipment should be provided with a thermal relief valve if the volume of blocked-in liquid is greater than 0.5 m3.

Of course it depends on the start pressure, the fluid and what are the start and end temperatures.
