Drill stems provided by Flowserve on recent projects have a swaged end that has a larger outside diameter on the female threaded end, compared to older designs. This improves the integrity of the threaded joint.
I agree that you need to inspect & maintain your drill stem regularly. Use the proper lube and tools when tightening the joints, and don’t ram the coke bed.
