Pipeline roping radius

[Danbury]

I am designing slurry pieline and need to calculate minimum radiys for roping to ensure stress of the pipeline within its yield strength, pipe size 28" std, 960kpag, 70 dec. C, API 5L Gr. B. I would greatly appreciate if anyone could share your knowledge with me.

Regards,

Danbury

bending stress Mc/I is proportional to pipe curvature, 1/R, which is proportional to M/E/I. Set them equal and solve for R_min
