Api 16a All Size Double Rams Bop - Chinaprice: contact company for price
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.
Rams, or ram blocks, are of four common types: pipe, blind, shear, and blind shear.
Pipe rams close around a drill pipe, restricting flow in the annulus ( ring- shaped space between concentric objects) between the outside of the drill pipe and the wellbore, but do not obstruct flow within the drill pipe. Variable- bore pipe rams can accommodate tubing in a wider range of outside diameters than standard pipe rams, but typically with some loss of pressure capacity and longevity.
Blind rams ( also known as sealing rams) , which have no openings for tubing, can close off the well when the well does not contain a drill string or other tubing, and seal it.
Shear rams cut through the drill string or casing with hardened steel shears.
Blind shear rams ( also known as shear seal rams, or sealing shear rams) are intended to seal a wellbore, even when the bore is occupied by a drill string, by cutting through the drill string as the rams close off the well. The upper portion of the severed drill string is freed from the ram, while the lower portion may be crimped and the â€œfish tailâ€ captured to hang the drill string off the BOP.
