Hi
What is the concept for adding 'H' as hanger load in hydrotest in 'Recommended' load cases in CII? By test I think it makes no difference for hydrotest loads since it's assumed to be rigid.

No answers?

H- Hanger loads are obtained in HYD case considering hanger stiffness as rigid

See in load case options tab
Hanger stiffness is considered as Rigid

This would replicate the Locked condition of spring (infinite stiffness)during hydro test.


From carpenter and paterson installation manual

"1.2 PRESETTING
All constant supports are fitted with preset pins. These pins are factory positioned within the unit
to suit the customers specified installed condition. On completion of installation and prior to
removal of pins, the pipework system can be hydraulically tested or acid cleaned without further
deflection of the spring assembly. The preset pins must be removed before commissioning the
system (refer to installation instructions)."

Thanks stressguy81

yes, but what is the aim for adding H in HYD. Does it make any difference if it's omitted? I tested that and I found no difference.

Yes, it should be added.
