Clamp shoe anchor on 5D Bend

I have 28" hydrotransport slurry discharge line (API5LB).From pump discharge nozzle, there are 2 victaulic couplings and 5D bend, to hold pressure thrust force, there is a need to have anchor support on 5D bend, since no place to have dirctional anchor before 5D Bend. On Caesar model, I place anchor at bend middle point but it is not on the bend center line curve therefore no offset distance creating bending moment (arm length), it is not realistic. I did SIF check and found that 5D bend 28" SIF=1 so I modelled straight to the point exactly where the 5D bend middle point is located and placed anchor there. Can anyone comment on this method or do you have any good suggestion?
28 5D bend anchor support shows 45 degree clamp in the middle of the bend bottom plate bolted to the structrue (4 no each side).

Thanks in advance.

Can you model a 45 degree 5D bend, then a very short straight piece of pipe, then another 45 degree 5D bend, and put your anchor on the short straight piece in between?

no, no enough length after 45 bend.

Support on victaulic couplings bends not possiable.change to welded elbow. check with victaulic couplings vendor for this type of supports.
temp is less than 120 Deg.

Check which type of coupling to be used.

Mr. Flames,

You could follow Mr. Dave's recommendation as an approximation. Add a few extra 'mm' to your model to make it work. Dont worry about the little bit of difference in the model dimensions. If your system is not strictly stiff, it will not make a dramatic difference in the results, but you will be able to get a feel of the stresses for starters. Dont forget to apply a suitable SIF at the intersection with the bend.

If stresses are significantly high, you should seek a FEA program to check the local stresses.

Best Regards,
