Dear Friends,

Supports are located in horizontal pipe based on bending stress and deflection, but I would like to know how and what basis a support is placed on vertical piping. I viewed some vertical vessel piping arrangements; all the vessel piping arrangements are supported at the top, downside following by guides and after the bends either rest support or a spring hanger.

1. How to model a support in CAESAR II which moves along with vessel up and down with respect to vessel displacement?

2. Vessel Nozzle loads, How to reduce it? What if the pipe is “too long”.

3. If there are no possibilities to provide a support for vertical piping from vessel. How to place a support in piping arrangement?

4. How to support a Vertical piping when it is not connected to vessel? On what basis?

Show me few guidelines & books to refer which will be very useful. Thanks in advance.
