Hi. We work with equipment recovery. We need to manufacture a component with a DI-22 - 8 1/4" thread. I need the manufacturing measurements or standard for this thread. Can you help me?

RE: Connection DI-22
It looks like this is from Drilco Industrial and developed several decades ago.
There is a patent listed https://patents.google.com/patent/CA1138490A/ but with no dimensions and no one seems to know the dimensions or manufacturing set up other than the current manufacturers!
Ring these guys and ask them, but think they might decline to provide you with their proprietary information. https://www.bddrill.ca/raiseboring-tools/
or https://www.micon-drilling.de/Download/RaiseBore_d...

So it doesn't look like a "standard" per se but a proprietary thread manufactured by a select bunch of drill pipe suppliers.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
