For piping in dual phase flow, is it mandatory to have piping supports type as spring hangers?
If not, in which cases spring hanger supports are considered to be installed. Share some reference guidelines to understand this better,
Dual phase flow & piping spring supports
Re: Dual phase flow & piping spring supports
No, that is not correct, two-phase flow does not automatically mean that using spring supports is mandatory.
They are mainly selected to support vertical movement and load sensitivity, not because the fluid is two-phase.
Typical installations are on hot lines with considerable vertical movement at the support, only then a spring element may be required.
Talking about references, you would find MSS SP-58 & 69 useful on spring supports selection, application, types, and materials.

Re: Dual phase flow & piping spring supports
Other than the hot lines, temperature driven, where else spring support hangers are applied on piping?
Unfortunately I do not have access to the standards you mentioned.

Re: Dual phase flow & piping spring supports
It is not the high tempearture application where spring supports are applied.
They are considered for cases like:
1. Operating weights are significantly higher (you need springs to support)
2. Equipment nozzle & piping connection are sensitive, movement control is needed
3. Offshore application - external factors causing movements (again you need springs)
4. Environment with inherent vibration /movement
Hope you understand.

Re: Dual phase flow & piping spring supports
Rather thinking about applying spring supports on hot temperature lines, just consider this:
Use springs/constant supports when any of these is true:
1. Vertical thermal movement at a support is significant and a rigid support would overload nearby supports/nozzles.
2. Connected equipment (compressors, exchangers, turbines) has tight allowable nozzle loads - you need near-constant support reaction.
3. You have sustained operating cases with materially different weights that must be accommodated without large reaction swings.
4. The piping stress model shows supports lifting off / going negative / big load shifts in operating case.
Otherwise, rigid supports + good guiding/restraint is normal.
