Interior BOP Valves
The one-piece and two-piece IBOP valves from Don Mashburn, Inc. are dart-style positive check valves in the drill string. These are non-return check valves that allow pumping through the valve into the drill string and provide a one-way positive seal that prevents the well from experiencing an uncontrolled kick up the drill string, protecting the swivel, standpipe, and pumps.
Features
The one-piece and two-piece IBOP valves from Don Mashburn, Inc are positive dart-style check valves in the drill string. These are non-return check valves that allow pumping through the valve into the drill string and provide a positive one-way seal that prevents an uncontrollable kick from rising up the drill string, protecting the swivel, standpipe, and pumps.
Kelly valves
The one-piece and two-piece Kelly valves from Don Mashburn, Inc. are designed for high-pressure conditions and will maintain pressure in both directions, providing a positive seal in the event of a kick. Having full-bore openings also allows for the unrestricted flow of drilling fluid, reducing wear on critical parts while providing unrestricted access to downhole tools. The one-piece Kelly valve is another variation of the two-piece where length or workspace is problematic.
Features
- Compact, easy to handle, and maintains great strength and durability.
- Working pressure of 10,000 psi with 15,000 psi available.
- Both the upper and lower valves meet API specifications and our own strict testing.
- One-piece valves save space in the string.
- Standard and full opening available.
Safety valve
The ball-type safety valve is designed to be inserted into the upper joint of the pipe or drill pipe on the rig floor and quickly shut off in the event of a well blowout. After adding heavy material to the mud, the Kelly valve can be reconnected, the safety valve opened, and circulation started.
Side Entry Sub
LATERAL ENTRY INTEGRAL SUBS Don Mashburn, Inc. offers a complete line of lateral entry subs. One-piece and two-piece configurations are available and are manufactured with internal Stub-Acme threads. Our two-piece sub is machined and threaded, not welded, for increased strength and reliability.
