20000PSI Ultra-high-pressure BOP Stack
Manufacturing Standards: API 16A, GB/T 20174 Product Applicability: Deep, Ultra-deep wells are mined with high formation pressure, should use ultra-high pressure BOP stack to ensure well control safety Product Features 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 connect ed with the shell by jaw chunk, the packing element is taper type, and the sealing parts are exchangeable with imported products
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
