You also have to check if the crude oil need a HIC tested material, check the allowable stress for the internal pressure and check the weldability of the grade replaced with the existing one (Equivalent carbon).
Hi Carf,
I've seen your pressure drop calculator.I've done some excel files with various geometries (cylindric, rectangular, diverter, blades obstacles-sinlges or multiples).
I can give you my references regarding your query :

hello deasdi,
hereafter you will find a simple method from Idelcik.
You have equivalent length for the elbows, and correction factor following their angle (K) when the ratio (r/d =1.5 )
d (mm) L_equiv (m)
25 0.35
50 0.75
75 1.18
100 1.60
125 2.05
150 2.50
175 2.93
200 3.35
225 3.76
250 4.18...
