Cameron U type Blind Shear Ram assembly

SHEARING BLIND RAM

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

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.
