Designing conical threads 2

[Daniel10]

I don't know if there is an EURONORM for designing conical threads. I have ANSI/ASME B1.20.1-1983 - Pipe threads, general purpose(inch), but there isn't sufficient.I used NPT Threads for LPG skids and I need the calculation of an assembly with conical threads for shearing, traction,....etc.
Please help me solve this problem.
I thank you!

This is a standard oilfield design problem. You can use the API specifications for EUE, NUE, STC or LTC threading. I do not have access to that specification right now, but will post the exact bulletin number.

Good luck. Calculations are imperial but can be easily converted to metric.
