DRILL PIPE FLOAT VALVES

Baker SPD manufactures a complete line of float valves, repair kits, and puller assemblies to accommodate a wide range of drilling situations and operating conditions, including H2S and steam service. These Drill Pipe Float Valves provide added blowout protection at the bottom of the drillstring, prevent flowback when joints are added, and keep cuttings out of the drillpipe to prevent bit plugging while making connections.

MODEL F DRILL PIPE FLOAT VALVES

BAKER SPD MODEL F VALVES BENEFITS AND FEATURES A fast-acting plunger valve opens when the kelly is pulled out of the hole, then closes, eliminating breakage of a wet joint. The plunger type valve also prevents flowback when adding joints and keeps cuttings out of the drill pipe, preventing bit plugging while making connections. The likelihood of having to pull a wet string with its attendant safety hazards and expensive down time is eliminated.

CONSTRUCTED FOR LONG LIFE Models F and FC Drill Pipe Float Valves are made of low carbon steel suitable for most applications including H2S conditions. It is designed and constructed with minimum number of parts-all highly resistant to wear to give long trouble-free service.

EASILY SERVICED Normally, the only service required is replacement of the valve seal. This can be accomplished in seconds without special tools. The valve guide at the lower end of the valve stem is simply raised, compressing the spring and allowing for removal of the entire inner portion of the valve. Baker SPD Drill Pipe Float Valves are easily installed by simply lubricating the side seals and sliding them into the cavity in the float sub or drilled out drill collar. Care must be taken in positioning the float valve in the drilling string. If it is placed too far from the top of the hole and the pipe is not filled while running in, hydrostatic pressure could cause damage to the drill pipe or the float valve. If the pipe is filled while running in, the float valve can be placed just above the bit, if desired.

BAKER SPD NOW OFFERS TWO NEW DRILL PIPE FLOAT VALVE CONFIGURATIONS The Model FA offers all the standard features of the Model F Float Valve with the added feature of a port which allows a fluid path through the center of the valve. This feature allows for an automatic partial filling of the drill pipe during run in. This valve is used when monitoring the bit head for gas pressure and/or gas pockets, allowing measurement of differential pressure when required. The Model FA is available in all sizes. The Model FI also offers all the standard features of the Model F Float Valve with the added feature of an integral baffle plate at the top of the float valve. For operations where a baffle plate is always used for instrumentation or fluid control the integral baffle plate configuration offers and economical option. The Model FI is only available in sizes 4R and 5F-6R.

Product Family No. H48018 The Model FC Automatic Fill Valve is ideal to use when drilling deep wells. The automatic feature on the Model FC allows the drillpipe to fill from the bottom, thereby removing the mess, hazards, and lost time from filling. When running in the hole, the automatic fill feature eliminates the “ram effect” preventing the downhole pressure surges that can cause formation damage. The Model FC is slotted on the stem to accept a low carbon “automatic fill” key assembly that is automatically released by fluid circulation releasing the plunger for complete closure.

The “Heavy Duty” Model F Drill Pipe Float Valve is designed with a high alloy steel body that increases the lift of the Drill Pipe Float Valve. It provides high impact resistance and is dimensionally identical to the standard Baker Drill Pipe Float Valve, allowing interchangeability of the trim. This type of Drill Pipe Float Valve is recommended for use with downhole mud motors.

MODEL G DRILL PIPE FLOAT VALVES

BAKER SPD MODEL G VALVES BENEFITS AND FEATURES Flapper Valves for G Models are made of normalized, carburized, quenched, and tempered alloy steel to resist wear and erosion. The flapper valve opens fully during circulation providing an unrestricted bore through the valve thereby effectively prolonging the life of the valve and drill collar as there is no diversion of fluid against the drill collar ID.

CONSTRUCTED FOR LONG LIFE Dampeners have been provided at the three most common points of wear due to vibration. The shock absorber has been placed at the bottom of the valve cage to prevent valve to bit wear. The flapper valve is provided with a resilient bumper to prevent wear between it and the valve cage or drill collar ID. The hinge pin is coated to protect against wear from vibration. Like all Baker SPD Drill Pipe Float Valves, G Models are designed for long life, fast installation, (no tools are required), and trouble free operation.

EASILY SERVICED Particular attention should be given to the hinge pin, spring, and rubber parts. Since the seal is not in the fluid flow pattern it receives little wear and seldom is replaced. When replacing the seal, the handle of the float valve puller may be used to remove the seal retainer, and after installation of a new seal, used to reinstall the seal retainer. To remove, insert the handle of the float valve puller into the upper end until the beveled edge of the handle seats on the beveled edge of the seal retainer. The seal retainer can then be knocked out. In this instance, the seal retainer should also be replaced. Note: Caution should be used to prevent the valve face from being damaged.

The Model G “Flapper Type” Full Open Valve incorporates a specially designed flapper which opens quickly and fully to provide a completely unrestricted bore through the valve. The Model G is especially good for use with highly abrasive fluids. When circulation stops, the flapper closes instantly to prevent cuttings from entering the drill string and plugging the bit. The valve opens when the first joint is raised out of the hole assuring the first joints drain and are not pulled wet. This saves mud and avoids safety hazards and down time. The flapper-type valve complements primary blowout prevention equipment to provide complete internal pressure control.

Product Family No. H48019 The Model GC Automatic Fill Flapper Valve uses a low carbon steel “automatic fill” key assembly that allows the pipe to fill from the bottom, reducing run in time by eliminating the need to fill the string from the top. When running in the hole, the automatic fill feature eliminates the “ram effect” preventing the downhole pressure surges that can cause formation damage. The valve can be run in either the closed position or the automatic fill position. The fast acting flapper valve opens when the kelly is pulled out of the hole reducing the possibility of pulling a wet string along with the associated safety hazards. Mud spill-over on the rig floor is also eliminated. These timesaving features allow the Model GC to quickly pay for itself.

The Drill Pipe Float Valve is installed near the top of the drillstring. Escaping air is channeled under the flapper valve, forcing it closed, and preventing loss of pressure. Note: In order to lose as little air as possible from the drillstring when a joint is made up, it is recommended that the float valve be moved up in the drillstring each time a new bit is installed. Caution must be exercised, however, to keep the valve at least one joint below the kelly; otherwise, the valve could be blown out of the drillpipe by trapped pressure when the kelly is removed.

Each time the tool joint box is recut, however, the shoulder of the lower end of the body bore must be cut back to maintain dimension “A”. The body bore length permits approximately 1/4 in. travel of the valve, and this travel should be maintained when the body is recut. Bodies longer than the standard 3 ft in length allow more recuts and can be furnished on special order.
