What is a BOP Ram Block or Ram Blocks?
A BOP ram block is a critically machined pieces of metal that works in conjunction with elastomeric ram packers and top seals to affect a seal in the wellbore cavity of a blowout preventer. Ram blocks can be either Pipe bore rams, variable bore ram blocks, or shear ram blocks.
What does a Ram Block do?
BOP Rams literally ram together towards an open hole or a pipe and allows the control of the pressure underneath the ram blocks. Ram blocks are extremely critical to drilling operations and may also help during stripping operations and or kicks in wells. Pipe bore ram blocks are designed with a fixed pipe or casing bore. Variable bore ram blocks are designed to offer a range of pipe sizes it can close on. Shear ram blocks are designed to shear drill pipe in an emergency, and may also be offered with the ability to close off the well. See above the types of ram blocks we manufacture.
