Ram Type Blowout Preventers

A ram-type BOP is similar in operation to a gate valve, but uses a pair of opposing steel plungers, rams.

A ram-type BOP is similar in operation to a gate valve, but uses a pair of opposing steel plungers, rams. The rams extend toward the center of the wellbore to restrict flow or retract open in order to permit flow. The inner and top faces of the rams are fitted with packers (elastomeric seals) that press against each other, against the wellbore, and around tubing running through the wellbore. Outlets at the sides of the BOP housing (body) are used for connection to choke and kill lines or valves.

Ram BOPs for use in deepwater applications universally employ hydraulic actuation. Threaded shafts are often still incorporated into hydraulic ram BOPs as lock rods that hold the ram in position after hydraulic actuation. By using a mechanical ram locking mechanism, constant hydraulic pressure need not be maintained. Lock rods may be coupled to ram shafts or not, depending on manufacturer. Other types of ram locks, such as wedge locks, are also used.

Ram Type BOP

A ram-type BOP is similar in operation to a gate valve, but uses a pair of opposing steel plungers, rams. The rams extend toward the center of the wellbore to restrict flow or retract open in order to permit flow.

Annular Type BOP

An annular blowout preventer uses the principle of a wedge to shut in the wellbore. It has a donut-like rubber seal, known as an elastomeric packing unit, reinforced with steel ribs.

Ram Blocks

The closing and sealing component on a blowout preventer. One of three types – blind, pipe, or shear – may be installed in several preventers mounted in a stack on top of the wellbore.

API 20E Bolting

The providing API 20E Bolting, Cansco guarantees that the products are manufactured and tested under the most extreme conditions. Cansco is able to provide (BSL) Bolting Specification Levels in the three-existing levels, which prove our commitment with technology and engineering excellence.

Diverter Packages

A system used to control well blowouts encountered at relatively shallow depths and to protect floating rigs during blowouts by directing the flow away from the rig.

Manifolds – Choke & Kill/Testing

An accessory system of piping to a main piping system (or another conductor) that serves to divide a flow into several parts, to combine several flows into one, or to reroute a flow to any one of several possible designations.

BOP Control Units

A device that stores hydraulic fluid under pressure in special containers and provides a method to open and close the blowout preventers quickly and reliably. Usually, compressed air and hydraulic pressure provide the opening and closing force in the unit.

Chokes – Hydraulic, Manual & Fixed

Provide flow restriction in high pressure applications such as choke manifolds, flow through manifolds and test manifolds.

Drilling Valves – Gate, Ball, Plug & Check

Generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Closing the valve is accomplished by spring force within the valve operator and by some means of assist from line pressure.

Adaptors – BOP & Well Head

Provides the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.

Drilling and Diverter Spools

Drilling spools allow the smooth circulation of mud during drilling operations and usually have the same nominal top and bottom end connections. Side outlet may differ from each other. Top, bottom and side end connections can be hub end or flanged.

Riser – Flange x Flange

Pipe and special fittings used on floating offshore drilling rigs to establish a seal between the top of the wellbore, which is on the ocean floor, and the drilling equipment, located above the surface of the water.

Choke and Kill Hoses

For drilling and service both onshore and offshore in applications as choke and kill lines. Choke and kill hoses are essential to control the well control equipment.

Chiksan / Treating Iron

These rugged fittings come in 3/8- to 12-inch sizes and can handle cold working pressures up to 20,000 psi. Chiksan swivel joints are available for sour gas services at cold working pressures up to 15,000 psi.

BOP Test Pump & Bolt Torque Unit

Cansco BOP test systems and pumps are designed and packaged in a variety of formats to suit the specific location, operating, and application requirements.

BOP Test Stump

BOP Test Stumps are used at off-shore and on-shore drilling rig to test Annular Type of BOP for locking mechanism test and sealing mechanism test.

Test / Blind Flanges

A projecting rim or edge (as on pipe fittings and openings in pumps and vessels), usually drilled with holes to allow bolting to other flanged fittings.
