26 3/4 Large bore size Ram BOP Manufacturing Standards: API 16A,GB/T 20174 Product Applicability: For high output oil and gas fields that require drilling wellbore with large drift diameter, corresponding large bore size BOPs shall be equipped. Nominal diameter 26 3/4″ 177ºC Temperature Level PR2 Performance Level WELL CONTROL BOP STACK EQUIPMENT It is a large bore size BOP series, have Shaffer and U type The structure is optimized and the shape is compact It has high corrosion resistance as its main sealing parts have special surface treatment It can be equipped with a tandem booster to achieve high level shearing function Application example: Southwest of China, Kuwait, Iraq, Kazakhstan, South America Product Features Technical parameter Nominal diameter 679.45mm (26 3/4″) 20.7MPa (3000psi) Rated working pressure of hydraulic control system 20.7MPa(3000psi) Recommended operating pressure 10.35Mpa(1500psi) Temperature Ratings for Metallic Materials T-20/350 Temperature Ratings for Nonmetallic Sealing Materials Highest BFF Hydrostatic test pressure of the body 31.05MPa (4500psi) Rated working pressure Sulfur resistance level Performance Level PR2 NACE MR0175
20000PSI Ultra-high-pressure BOP Stack 20000psi Ultra high pressure 177ºC Highest temperature level PR2 Performance level Application Cases:High pressure oil and gas fields in Xinjiang and Southwest China, Russia high pressure oil field The floating sealing structure is adopted between the intermediate flange and the shell, which ensures stable sealing performance and reduces the tightening torque of the side door bolts The ram is replaced by taking out from the side, and reducing the overall height of the BOP stack, which easier to replace the ram The shell, intermediate flange, hydraulic cylinder, piston rod, cylinder sleeve, and ram shaft are subject to corresponding advanced surface treatment to improve the anti-corrosion of the parts and the reliability of the BOP FHZ28-105/140 Annular BOP is mainly composed of shell, piston, bonnet and other main parts. The bonnet is connected with the shell by jaw chunk, the packing element is taper type, and the sealing parts are exchangeable with imported products Product Applicability: Deep, Ultra-deep wells are mined with high formation pressure, should use ultra-high pressure BOP stack to ensure well control safety Manufacturing Standards: API 16A, GB/T 20174 WELL CONTROL BOP STACK EQUIPMENT Technical Parameters Nominal diameter 279.4mm (11″) Rated working pressure of hydraulic control system 20.7Mpa(3000psi) Recommended operating pressure 10.35Mpa(1500psi) The pressure of hydrostatic proof test Ram BOP 207MPa (30000psi) Annular BOP 155.25MPa (22500psi) Rated working pressure Ram BOP 138MPa (20000psi) Annular BOP 103.5MPa (15000psi) Temperature Ratings for Metallic Materials Sulfur resistance level Ram BOP Highest T-20/350 Annular BOP Highest T-20/250 Temperature Ratings for Nonmetallic Sealing Materials Ram BOP Highest BFF Annular BOP Highest BBD Performance level PR2 NACE MR0175
