My wishes to all,
In My experience ,
- Having expansion loop at suction side of rotating equipments are not
advisable ( cold pull, no way, please let me know if you happen to
experience any where ).Generally suction piping should have minimum number
of bends so that friction losses shall be very minimum. selecting spring
supports or suitable expansion bellows are the best & workable solution.
- Discharge is concern , expansion loop is preferable for offsite pipe
routing ( other than plant ). For inside plant and equipments, spring
supports are preferable.
Over and above, Negotiations can be made to pump vendors to accommodate
additional nozzle loads to some extent.
Cold pull could be the last ( better avoid ) option for offsite pipe
routing.
This is my opinion.
Please feel free to add / disagree,
Regards,
