| Name | BOP_Ram |
|---|---|
| Entity Type | Extension of Blowout_Preventer |
| Description | The closing and sealing component on a ram type blowout preventer. One of three types--blind, pipe, or shear--may be installed in several preventers mounted in a stack on top of the well bore. Blind rams, when closed, form a seal on a hole that has no drill pipe in it; pipe rams, when closed, seal around the pipe; shear rams cut through drill pipe and then form a seal. |
