SHEAR RAM BODY BLADE SEAL,TOP SEAL ,SIDE SEAL

Cameron shearing blind rams (SBRs) shear the pipe in the hole, then bend the lower section of sheared pipe to allow the rams to close and seal. SBRs can be used as blind rams during normal drilling operations

Type :Annular BOP, Single Ram BOP, Double Ram BOP, Shear Ram BOP

Standard: A P I Spec 16A,16C
Working pressure:2000psi-15000psi(14 Mpa-105Mpa)
Operating temperature:-18deg--121deg
Bore size:7 1/16"-21 1/4"
Top & nottom connection:Flanged,studded

Characters of BOP spare parts:

In the structure, it is divided into annular blowout preventer with spherical plastic core, annular blowout preventer with cone-shaped plastic core, and blowout preventer with tube-shaped plastic core. Annular BOP top cap and housing are connected by bolts or claw blocks.
Blowout preventer with spherical plastic core and dust-proof ring.
Performance characteristics: reasonable structure, easy operation, long life of plastic core, adapt to a wide range, capable to seal pipe string with nominal paths from 0-DN in ans shapes, better performance by combining with ran blowout preventer in the use.

Working of BOP spare parts:

When wells must be sealed in case of kicks high pressure (10.5Mpa) oil from control systems enters into close-cavity under piston from housing oil outlet, to promote plastic core moving upward along ball surface, so that bearing tendons move closer to each other to moce the rubber between them to the center of wellhead so as to seal drilling tools or fully seal wellhead. In opening , hydraulic pressure oul enters into open-cavity above piston from housing oul inlet, to push piston moving downwards , so that plastic will reset with its own elasticity, wellhead will be open.

Brand of BOP spare:SHENKAI BOP. RONGSHENG BOP ,CAMERON BOP,SHAFFER bop

Features include:

Large frontal area on the blade face seal reduces pressure on the rubber and increases service life.
Cameron SBRs can cut pipe numerous times without damage to the cutting edge.
The single-piece body incorporates an integrated cutting edge.
CAMRAM™ top seals are standard for all Cameron SBRs.
H2S SBRs are available for critical service applications and include a blade material of hardened high alloy suitable for H2S service.

DVS rams are shearing blind rams which are similar to SBRs with the following features:

DVS (double V shear) rams fold the lower portion of the tubular over after shearing so that the lower blade can seal against the blade packer
DVS rams include the largest blade width available to fit within existing ram bores.

Shear ram is composed of upper ram body ,lower ram body, top seal,right seal, left seal and tool face seal. Tool face seal is placed in th front slot of the upper ram body,with right seal and left seal on the both sides. The shear ram is installed in the BOP in the same manner sa the common ram.but need to replace tha hanger pf the main piston to hunger. otherwise it will not be used.
