Dear All .

I am performing Stress Analysis for a 36 " Offshore line carrying oil Sp. Gravity nearly 1. Pipe Thickness is 25.4. Feasible Supporting span is 30m.

My Sustain Stress is 65%.
Expansion Stress is 50%
Max Sustain Displacment is 40mm.

I would like to know , whether the Sustain deflection of 40mm is acceptable .Any thing to be cinsidered when sustain displacements are big .

Kindly advise me ..

I have restricted my Previous Systems to a max Sustain Dispalcement of 15mm

Regards
Bala
