They are the annular preventer, blind ram, blind shear ram, and the pipe ram. There can be many different configurations, sizes, and pressure ratings, dependent on well design, formation pressures, and areas of use. The BOP is attached to the steel casing that is cemented around the well bore.
The drill string is suspended through the center of the well bore. This is the rotating pipe to which the drill bit is attached. The first BOP component is the pipe ram. During a kick, this ram is activated and creates a seal between the well bore and the outside of the drill string. The next component is the blind shear ram. If a kick occurs, it may become necessary to sacrifice the drill string to stop the flow of material inside of the well bore.
It also allows for a controlled flow of oil when necessary. See if the model you need allows remote work. These crucial parts for BOPs include flanged crosses, drilling spools, male and female adapters, and more for building and repairing quality BOPs. The equipment can be customized to fit whatever you may need for a BOP. The basic function of a blowout preventer is, of course, to prevent an oil blowout.

Accumulator The main control unit is called an accumulator. Annular and RAM An annular BOP is what closes the space around the diameter of the drill pipe , but since the actual system cannot be closed with a value due to the drill string, this controls the air flow for the mud without cutting off any other systematic elements.
Types can include: Blind RAMs, which close over any portion that lacks a drillstring Choke manifolds, a system of adjustable variables and pressure sensors that allow for the control of various fluids in different directions. The choke line valve assists in directing mud to the choke manifold when a kick occurs.
A kill line valve, which acts as a backup to the standard drillpipe A casing RAM that can adjust to close around different piping sizes in the event of a kick RAM valves can be stacked a number of different ways, for multiple types of efficiencies.
