I have a DN20 threaded ball valve, and to connect it to tees, are there tees with external threads available? How should the two be connected?
Connect directly to pipes with DN20 external threads. No need for male and female ends.
Does the pipeline get larger after the valve is installed? DN20 should be 3/4”, assuming the reduction is 2”/DN50. So, the following fittings are available: 1. Reducing Hex Nipple, with external threads on both ends, sized at 2" and 3/4 respectively" ； 2. Female-Male Reducer, but it seems to be able to reduce the diameter only from 3/4\" external thread to 1.5\" internal thread.
Use a single-threaded end, and then weld a larger and smaller end later.
If you’re not bothered, it’s always possible to connect. There are ones with internal threads of different sizes, those with external threads that have a direct end – all kinds exist
First, process a DN20 pipe with threads, and then weld pipes with reduced diameters according to your actual requirements.
