EUE Type Manual BOP Shaffer Ram Blowout Preventer With High Pressure Rating

The EUE sucker rod blowout preventer (BOP) is a wellhead safety control device specially developed for workover operations in oil and gas fields. It is core-matched with EUE (External Upset End) threaded sucker rods and is mainly applied to wellhead-opening operation scenarios such as sucker rod running and pulling, polished rod replacement, positive squeezing plug removal, and well flushing. Its core function is to quickly block blowout channels through precise sealing and mechanical locking mechanisms, effectively preventing oil and gas leakage, protecting the safety of operating personnel, the integrity of equipment, and avoiding environmental pollution. It is an indispensable well control key equipment for rod pumping well downhole operations.

The product strictly complies with the API 16A blowout preventer design and manufacturing standard, SY/T5053.1-2000 Blowout Preventers and Control Devices – Blowout Preventers, and SY/T5127-2002 Specifications for Wellhead Equipment and Christmas Trees. It has obtained ISO 9001 quality management system certification and passed third-party authoritative testing. All components have undergone high-pressure pressure testing, fatigue cycle testing, and corrosion testing, and the key performance indicators meet the well control management rules of mainstream oil and gas enterprises such as CNPC (China National Petroleum Corporation) and CNOOC (China National Offshore Oil Corporation).

Various downhole operations requiring wellhead opening, including sucker rod running and pulling in rod pumping wells, polished rod replacement, well flushing and sand washing, fracturing and acidizing, and plug removal.

Effectively controls blowout risks and reduces the incidence of operational safety accidents; simplifies installation and operation procedures and shortens non-productive time; adapts to various well conditions and sucker rod specifications and reduces equipment adaptation costs; meets environmental protection requirements, avoids environmental pollution caused by oil and gas leakage, and helps oilfields achieve safe, efficient, and green operations.
