"50 Transition Joint" (50 transition joint) is an important connecting accessory for various drilling RIGS and other drilling and production equipment. Its core value focuses on "universal compatibility with corresponding specifications + stable transmission of gas and liquid media + reliable support for drilling and production scenarios", building a stable component connection bridge for the drilling and production systems in mines and engineering drilling. Its core function is to achieve the transitional connection of different pipelines and components of drilling and production-related equipment without the need to modify the original interfaces of the equipment. It can be compatible with various drilling and production-related equipment of corresponding specifications (such as medium-sized down-hole drills, hydraulic-driven drills, etc.), eliminating from the source the loosening or leakage of gas and liquid media caused by connection mismatch, and ensuring the uninterrupted trans…
