Blind Ram Vs Shear Ram

Blind Ram Vs Shear Ram. “Information that shows the blindshear rams installed in the BOP stack (both surface and subsea stacks) are capable of shearing the drill pipe in the hole under maximum anticipated surface pressures” Therefore an operator is responsible to assure the BOP shear rams will reliably shear the drill pipe in the particular operational conditions.

Blind rams have a flat elastomer face and are designed to shutin the well when there is no pipe across the BOP stack Blind/shear rams are designed to close in the well whether or not pipe is present If pipe is across the stack it will be cut by the closing blades in the ram block.

Shear Rams vs Blind Rams: What's the Difference? BOP Products

Blind Shear Ram (BSR) A closing and sealing component in a ram blowout preventer that first shears certain tubulars in the wellbore and then seals the bore or acts as a blind ram if there is no tubular in the wellbore NOTE Other common names for this ram include shearing blind shear or blind/shear rams.

SHEAR RAM CAPABILITIES STUDY

A blind shear ram is the thick heavy steel component of a ram blowout preventer (BOP) Blind shear rams are always fitted with hardened tool steel blades designed to cut the tubing or the drill pipe when the BOP is closed It then fully closes to isolate or seal the wellbore completely Here’s what you should know about shear rams.

Blind rams can close a wellbore even when the well doesn’t have a drill string or any other tubing On the other hand shear rams have steel blades to cut through the drill pipe and seal off the well Now let’s delve a bit deeper into how the two ram BOPs work.
