pipeline re routing by avoiding 90 degree bends to 45 degree bends

[JoseEnb]

Dear Seniors,

I have been doing a fine tuning in pipeline re routing by avoiding 90 degree bends to 45 degree bends.
My question is for a 36 inch X70 11.8 mm WT pipeline what are are the advantage and disadvantage of uising 45 degree bend vs 90 degree bend.

Thanks
Joseph

OMG. Right again. I just couldn't do the math last night.:-(

30ft /30"OD * 1.5[°] = 18[°]

The rule of thumb is with a min bend radius of 40xOD = max bend of 1.5[°]/diameter
