Hello All,
A few days ago, a world known consultancy & EPC company suggested us the
following:
- While performing the static analysis (flexibility analysis) of the piping
systems, it is not necessary to consider the friction forces. The friction
forces are short time generated loads, and act on the system during the thermal
expansion. The friction forces diappears after the thermal movement of the
piping. That's why friction should be excluded from static piping stress
analysis (flexibility analysis).
- There will be no friction at the guide side surfaces or the limit stops. The
friction will be there only for the resting supports.
What are your views on these?
Regards,
Kaustubh
