You may have a problem regarding ordering the cross over to use on the rig because there are so many threads used for the operation. For example if you have just only three threads (3-1/2” IF, 4-1/2” IF, 7” BTC) for the operation. These are a total of 18 the possible crossovers that you may need as listed below.
3-1/2″ IF PIN X 4-1/2″ IF BOX
3-1/2″ IF PIN X 7″ BTC BOX
4-1/2″ IF PIN X 3-1/2″ IF BOX
4-1/2″ IF PIN X 7″ BTC BOX
7″ BTC PIN X 3-1/2″ IF BOX
7″ BTC PIN X 4-1/2″ IF BOX
3-1/2″ IF PIN X 3-1/2″ IF PIN
3-1/2″ IF PIN X 4-1/2″ IF PIN
3-1/2″ IF PIN X 7″ BTC PIN
4-1/2″ IF PIN X 4-1/2″ IF PIN
4-1/2″ IF PIN X 7″ BTC PIN
7″ BTC PIN X 7″ BTC PIN
3-1/2″ IF BOX X 3-1/2″ IF BOX
3-1/2″ IF BOX X 4-1/2″ IF BOX
3-1/2″ IF BOX X 7″ BTC BOX
4-1/2″ IF BOX X 4-1/2″ IF BOX
4-1/2″ IF BOX X 7″ BTC BOX
7″ BTC BOX X 7″ BTC BOX
You will get lost easily, won’t you??
As you can see, it is quite tricky to determine all possible required cross over especially when you have a lot of connections. Therefore we create an Excel file to help you do this task. We call this file as “Cross Over Generator”.
