Cross Overs UB

The "connection bridge" for drilling tools. Designed with different specifications of threads/interfaces at both ends, it enables precise connection of variable-diameter drill strings and tools (e.g., drill bits to drill pipes, casings to oil pipes). Forged from high-strength alloy steel, it resists pressure up to ≤150MPa, has excellent sealing performance, adapts to complex drilling conditions, and ensures coordinated operation of tools.
