Inside BOP Valves

M&M offers two variations of “dart type” inside blow-out preventers (IBOPs). The traditional style is two-piece and is similar in construction to other dart type IBOPs. Recognizing the need to reduce as many internal connections as possible we have also developed a one piece IBOP.

An IBOP is a “dart” type pressure sealing device that has a conical head which mates to a conical negative sealing surface. This design allows for one-way pressure containment.

One-Piece Inside Blow-Out Preventers

M&M’s one-piece IBOP offers all of the same functionality of a two-piece design but offers several key benefits. A one-piece design allows the IBOP to be shorter, creates a possibility for smaller outside diameters and eliminating the service break allows for quicker disassembly because there are no tourqing issues any tourqing requirements because there is no service break. One-piece IBOP’s require less manufacturing time and therefore a faster delivery is possible.

Upon request, two-piece IBOPs can be designed and manufactured to meet any industry standard as applicable.
