Ram Blowout Preventer Description: Ram BOP is an important part of well control equipment, with the switch flexible and effortless operation, safety, maintenance and simple. My company has a double plate BOP BOP hydraulic, single hydraulic ram BOP, manual single ram BOP, BOP and other manual double plate. 1, use can be closed annular space between the casing and the tubing string, can be closed wellhead. In a closed case, through the lower four or export pipeline connected to the housing flanking conduct drilling fluid circulation, spray section exile, killing and other operations. In exceptional circumstances, can be cut to achieve the plugging drilling purposes. Can be hung drill. Reducing the gate can be closed using a range of different sizes and suites string annulus. 2, structural features (1) structural features of the housing: ① shape: squarish general case, the middle gate chamber through a vertical drill holes through the horizontal movement of the gate. ② Connection: upper and lower three connections: planted wire connection, flange, clamp connection. Connecting flanges, bolts, clamps, rims size according to API standards. (2) gate structure and the use of features: double-sided with a gate, the gate below symmetry. Different sizes of drill just replace sealant ring and shutter half pressed quickly, the remaining parts can be interchangeable; sided with the shutter can not be reversible; shear ram can cut drilling and wellhead wellhead full closure; variable diameter paddle used in different sizes of drill string and the casing sealed within a certain range. (3) the characteristics of ram ram seal floating gate automatic sand and help seal the well pressure, automatic self into the role of the gate and. Ram BOP seal around the wellhead seal should also have to work, in order to achieve effective plugging, namely: sealed gate at the top of the shell, and the front gate and the tube sealed housing and door sealing, piston rod and side door seal. (4) The shutter locking means. Manual locking device is rotated by human hand wheel is turned off or locked gate. Note that when using a manual locking device is only used to close the shutter, you can not open the gate. To open the gate after the first use of the locking device must be manually reset to unlock, and then open the hydraulic ram.
