Looking for Load Rating calculations for drilling sub that takes in account the connections, material strength, OD, ID, etc. Also in case of a x-over how would the calculation differ.
If any one has the calculation then appreciate if you can share it or better if there is an excel calculator.
Best regards.
Hi,
Grant Prideco / NOV used to have an online calculator, however they removed it to free subscription access only. If it is still available it is probably what you are looking for. Suggest you contact your local NOV / Grant Prideco sales rep and he can give you access.
I have used it for calculation the correct make-up torque for tools / pipe etc. It includes all API, GP and some other connections.
Good luck
Simon
