54-70 Large Diameter RAM for High-Pressure Preventer Stacks (FZ54-70, FH5435/70)

54-70 Large bore size High-pressure BOP Stack Applicable example:Xinjiang and Southwest China, Pakistan High level shearing capacity: Single cylinders have extremely high shearing capacity, and can directly cut off 5 7/8", 23.4lb/ft, S-135-grade high-performance drill pipes and achieve reliable sealing performance at a rated working pressure of 70MPa after the cutting Ram hang-on capacity: It can ensure sealing at the rated working pressure while hanging the drilling tool, and the hanging weight can reach up to 600000lbs (272t) Side door and cylinder structure: The simple structural design reduces the labor intensity and difficulty in ram replacement Surface treatment: Different parts are subject to corresponding advanced surface treatment to improve their anti-corrosion and the reliability of the BOP Can realize the gas sealing Product Applicability: For high-yield oil and gas fields and superdeep well operations under high formation pressure that require drilling wellbore with large drift diameter, corresponding large-diameter and ultra-high-pressure BOPs shall be equipped. 21 1/4″ Bore size 10000psi Rated working pressure 177ºC Max temperature level 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 NACE MR0175 Performance Level PR2 WELL CONTROL BOP STACK EQUIPMENT Technical Parameters Nominal diameter 539.45mm (21 1/4″) Rated working pressure of hydraulic control system 20.7MPa(3000psi) Recommended operating pressure 10.35Mpa(1500psi) Hydrostatic test pressure of the body ram preventer 103.5MPa (15000psi) annular preventer 51.75MPa (7500psi) Rated working pressure: ram preventer Ram BOP 69MPa (10000psi) Annular BOP 34.5MPa (5000psi) Manufacturing Standards:API 16A,GB/T 20174 Product Features

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
