API RP 1102 Calculations too High?
API RP 1102 Calculations too High?
(OP)
For my structural loading path class, I have been tasked with presenting a design for an oil pipeline for our class to discuss.
I have been using the API RP 1102 for the codes but all my values come out way too high to make sense. I have currently only attempted calculations for the buried part, and honestly about to just throw the whole code away and just use actual calculations. They would prefer if I can use the code though.
Let me know if you have any insight!

Do they exceed allowable stress? They look low to me.
At 6 ft of cover, there shouldn't be any overstress to pipe, unless really thin walled, or being operated at a very high pressure.

Have you read about the DAPL? If I recall correctly, the main line is 30" diameter, API 5L X70 steel pipe, up 0.625" wall thickness.
