Ram type blowout preventer
Ram BOP is an important part of well-control equipments. It is mainly used to control wellhead pressure during drilling, workover operations and formation testing etc to prevent well blowout effectively
and realize safe construction.
Our ram type blowout preventers (BOPs) are in accordance with API 16A standards for low and high pressure
applications.All components such as the ram block assemblies, pistons, body, pressure seals, flanged or studded
end connections, and bonnets are remanufactured to API standards and are restored to a "like-new" condition.
Our rebuilt Ram BOPs are high quality units sold at a fraction of buying an OEM replacement RAM BOP.
Usages:
The ram blowout preventer is designed to seal off the well bore when drill pipe, casing, or tubing is in the well. In a BOP stack, ram preventers are located between
the annular blowout preventer and the wellhead. There are typically 3 or 4 ram preventers in a BOP stack. Flanged or hubbed side outlets are located on one or both sides
of the ram BOPs. These outlets are sometimes used to attach the valved choke and kill lines to. The outlets enter the wellbore of the ram preventer immediately
under the ram cavity. Other than sealing off the well bore, rams can be used to hang-off the drill string.
A pipe ram, closed around the drill pipe with the
tool-joint resting on the top of the ram, can hold up to 600,000 lbs. of drill string.
Category:
1. Classified as per ram quantity: Single ram blowout preventer; Double ram blowout preventer; Triple ram blowout preventer;
2. Classified as per ram shape:
Blind Rams: The rubber sealing element is flat and can seal the wellbore when there is nothing in it
Pipe Rams: The sealing element is shaped to fit around a variety of tubulars, which include production tubing, drill pipe, drill collars, and casing that will seal off the wellbore around it
Variable Bore Rams: The sealing element is much more complex and allows for sealing around a particular range of pipe sizes
Shearing Blind Rams: The blade portion of the rams shears or cuts the drill pipe, and then a seal is obtained much like the blind ram
Specification:
Bore Size: 7 1/16~16 3/4(180mm~680mm)
Working Pressure: 14~140Mpa(2000~20000Psi)
Ram Locking Device
A ram locking device is necessary to be fitted to all ram blowout preventers. This device is used whenever it is necessary to remove hydraulic operating pressure
from the "close" side of the ram operating system, but maintain the ram preventer in the close position. On BOP stacks that are used in a surface application, the ram
locking device is a threaded rod, referred to as a "lock screw". This lock screw reacts between the operating piston in the ram operating system, and the housing of the lock screw.
The locking device on a ram preventer that is used in a subsea application must be designed to be remotely actuated by either the BOP hydraulic control unit, or by the actual movement of the operating piston in the ram operating system.
