®THORNHILL CRAVER

A long time standard for safety and reliability in the oilfield, Thornhill Craver UNIBOLT Stem and Seat Adjustable Chokes are designed for high performance in critical applications such as gas wells with high pressure drops, abrasive flow and corrosive conditions.

The Thornhill Craver UNIBOLT Choke design is field proven in a wide range of applications.

Available with alloy steel or 12% chrome stainless steel body, it is provided with a ring-groove or taper-type seal depending on size and pressure.

Adjustable choke styles are standard, ”Long Nose” Heater, Force Balanced and Steam.

ADJUSTABLE CHOKES

Engineered for heavy duty, maintenance-free performance.The Thornhill Craver UNIBOLT Choke is commonly selected for a number of applications, including:

• Production Manifolds • Critical Services

• Wellheads • Well Testing

• Heaters • Well Clean-up

The UNIBOLT coupling between the body and yoke is a unique design feature that ensures superior reliability and safety over other methods. The connection is made by means of the UNIBOLT interlocking shelf design rather than by conventional threads or flanges.

FEATURES AND BENEFITSCOUPLING vs. THREADS FOR SAFETY

The UNIBOLT coupling between the body and yoke provides a higher degree of safety than conventional threads or flanges due to the greater amount of metal in shear. There are no threaded or flanged connections between component parts and the adjustable choke may be dismantled quickly for change of stem seats.

PLUGLOK allows pressurerelease, ensures safety.

SIMPLE CONVERSION TO POSITIVE CHOKEA blanking plug may be substituted for the yoke bonnet assembly to effect simple field conversion to a positive choke.

EASILY AUTOMATEDThe UNIBOLT Adjustable Choke is easily automated with pneumatic actuation. Yoke adapter assemblies for Fisher actuators are a standard design.

EASY MAINTENANCEOnly common tools are required. ACME Power Threads on the reduced diameter of the stem facilitate insertion through the packing assembly. Chevron-type packing, compounded with Teflon requires no lubrication. The stem seat and gasket can easily be removed for inspection and replacement if necessary.

For added safety, the stem can only be removed through the bottom of the yoke hub assembly.

STEM RING FOR SAFETYA “no-go” ring is an integral part of the tip end to prevent separation of the stemand the bonnet assembly in the event that thread deterioration causes the stem to release in an upward motion.

VARIETY OF END CONNECTIONS AVAILABLEThreaded; UNIBOLT Line Pipe or butt weld; flanged API or ASME connections are available. Chokes may be ordered with combined end connections and other manufacturers’ end connections are also available. Typically, other than threaded, the most economical is a choke body with UNIBOLT connections.

TWO SEAL DESIGN UTILIZEDThe ring-groove seal is a mechanical-typeseal requiring tightening of the unit to effect a seal. The taper-type seal is self energizing under pressure in both directions and secures between the yoke and body. On both seal types, the yoke member pilot fits snugly into the body, centers the stem in the seal and minimizes vibration.PLUGLOK BLEEDER PLUG FORSAFETY AND PRESSURE RELEASEEvery UNIBOLT Choke comes with the PLUGLOK safety system. The bleeder plug functions to indicate unexpected pressure as well as a means to relieve trapped body pressure. The bleeder plug insures safety because it must be removed before the nut member can be unlocked to open the choke for maintenance.

STYLES

STANDARD ADJUSTABLE CHOKEStem and Seat Adjustable Chokes are designed for high performance in critical applications such as gas wells with high pressure drops, abrasive flow and corrosive conditions.

LONG NOSE HEATER ADJUSTABLE CHOKEWhen installed on an indirect heater, with the outlet end of the elongated choke body fastened directly to the tube bundle, the choke seat area is completely surrounded by the hot water which is primarily used to heat the tubes. The heat generated in this manner has a beneficial effect in minimizing the severe refrigerating action resulting from metering high pressure natural gas.

FORCE BALANCED ADJUSTABLE CHOKEDesigned to handle high-pressure,high-volume applications, it employs an innovative force-balanced arrangement which allows for very low operating torque.

ADJUSTABLE STEAM CHOKEDesigned for use in steam injection and other high-temperature applications up to 800°F (427°C).

Optional Materials Corrosion resistant materials available.

Maximizing leverage for strong connections, Thornhill Craver UNIBOLT Couplings are the high-pressure, compact and lightweight alternative to API or ASME flanges for piping systems.

The UNIBOLT coupling ensures superior reliability and safety over other methods.The connection is made by means of the UNIBOLT interlocking shelf design rather than by conventional threads or flanges and provides a higher degree of safety than conventional threads or flanges due to the greater amount of metal in shear.

Supporting angle between nut member and plain hub equalizes pressure around the seal ring.

Nut member slips over lug hub, shelves engage when rotated.

Helical shelves in nut member wedge against external shelves on the lug hub, exerting tremendous pressure on the seal ring.

Tee head bolt when tightened, the helix angle of the shelves multiplies the bolt force approximately 6 1/2 times as it is transmitted to the seal ring. This force is further multiplied 3.1/4 times by the 18° included angle in the ring and groove seals. Since the helical angle is self-locking, the bolt is under no stress after the initial tightening.

Seal ring squeezes tightly between plain hub and lug for a strong seal. Plain hub fits over pipe end to facilitate joining with another.

FORCE BALANCED CHOKES

FORCE BALANCED DESIGN CONCEPT

The design of the Force Balanced Choke distributes the force of downstream pressure to the stem equally in every direction, eliminating the effects of upstream pressure entirely and minimizing the load on the stem threads.

The upper stem is designed so that it rotates in a bearing without rotating the lower stem, further reducing torque.

This design results in a Choke that is easier to operate than any other conventional type. In addition, the low torque eliminates the need for expensive gear operators.

LONG NOSE HEATER CHOKES

UNIBOLT “Long Nose” Heater Chokes incorporate the proven principles of the UNIBOLT Adjustable and Positive Chokes.

The main distinguishing feature of the “Long Nose” design is the additional length of the Choke Body.

When installed on an indirect heater, with the outlet end of the Choke fastened directly to the tube bundle, the Choke Seat area is completely surrounded by the hot water which is primarily used to heat the tubes. The heat generated in this manner has a beneficial effect in minimizing the severe refrigerating action resulting from metering high pressure natural gas through a small orifice.

The UNIBOLT “Long Nose” Heater Choke is the accepted leading performer in this application.

UNIBOLT “Long Nose” Heater Chokes are available in 6500, 10,000 and 15000 psi working pressures. A 6500 psi economy design is also offered (see following pages for details).

LONG NOSE HEATER CHOKES

The Thornhill Craver Economy Heater ChokeProvides Proven Dependability at Lower Cost.

Whether you are a fabricator of indirect-fired heaters or an end user, the Thornhill Craver 6500 psi Economy Heater Choke will take a big slice out of your operating costs. Several thousand trouble-free installations provide proof of long-term dependability.

For stem and seat trim, you may specify alloy steel, stainless steel or tungsten carbide. These parts are easily replaced and are completely interchangeable with UNIBOLT chokes. This means that you won't be faced with extra inventory if you use both types.

The bonnet has a recess to permit easy removal with a spanner wrench, avoiding pipe wrench gouging and other damage.

An indicator, calibrated in 64ths of an inch, allows accurate pressure control.Once adjusted to the desired pressure, a positive stem lock holds the stem firmly in position, preventing movement caused by accident or vibration.

The choke is also equipped with a safety pressure relief vent which warns the operator if there is pressure in the line when attempting to remove the bonnet.

The Thornhill Craver Economy Heater Choke is more cost effective than other chokes but it offers premium performance. Specify Thornhill Craver products from Cooper Cameron Valves Note: 1 - Tungsten Carbide Stem and Seat required for NACE Service.

The Packing Stays PutOutside temperature: -50°FSteam temperature: 800°FIt is reassuring to know a Thornhill Craver steam choke is on the job. Because when recovering viscous crude, you're completely aware of the monumental maintenance headaches a different choke can produce. Most use rotating stems, which can grab the packing and pull it out of place. It's downhill from there. Steam escapes, condenses and freezes, creating a granite-like buildup of ice on the choke, overnight. Even if temperatures are ambient, the nature of your problem doesn't change; a corrosive buildup can be as hard as the ice.

Fortunately, Thornhill Craver chokes don't use rotating stems. Stem movement is linear, one direction. It doesn't grab the packing so no leaks occur. Just reliable service.If packing adjustment is ever needed, the choke packing gland is easily accessible.

And if conversion from adjustable to positive action is required, again it's good Thornhill Craver is on the job. Our famous UNIBOLT coupling needs but one man and one wrench to release one bolt, for easy access. Time required: about five minutes (even at -50°F). Don't worry about the seals, UNIBOLT seals much better than conventional flanges. In fact, the seals are so good, only light derating is necessary for up to 800°F steam temperature.

‘X’ BEANS AND SEAT/BEAN WRENCHES

UNIBOLT ‘X’ BEANS SPECIFICATIONS

Since the advent of proration there has been an inherent need for quick, easy, means of accurately proportioning the flow of oil or gas through Positive Chokes. UNIBOLT ‘X’ Flow Beans, whose orifices are gauged in percentage increments of well flow rather than in fractional inch sizes, provide the operator with a means of flowing any given quantity of fluid or gas from a well with a degree of accuracy never before attained by Positive Chokes.

Precise Flow Control Since the well flow is directly proportionate to the orifice in the Flow Bean, a change, for example, from a 1/64” ban to a 2/64” bean results in a 300% increase in area. By contrast a change from a UNIBOLT ‘X-1’ bean to an ‘X-2’ bean results in an increase of only 10%. The larger size and ‘X-28’ to ‘X-405’ (approximately 13/64”) for 6” beans, are available in half sizes, 5% increments, and are designated as ‘X-285’, ‘X-295’, ‘X-305’, ‘X-315’ (for 6” bean) etc.

UNIBOLT ‘X’ Beans are available in 74 sizes in flow increments of 5% and 10%. There are 56 sizes of ‘X’ Beans now available to take the place of the 13 fractional sizes up to ‘X-42’ (approximately 14/64”).

Renewable Bean inserts up to and including ‘X-42’ (approximately 14/64”) are furnished as economical, renewable inserts; however, ‘X-43’ and larger beans are available in standard full 6” length, drilled full length.

File-Hard Beans UNIBOLT ‘X’ Beans are heat treated to produce a minimum harness of 60 Rockwell “C” and thus assure long, trouble-free service.

No Complicated Flow Computation Required Because UNIBOLT ‘X’ Beans are gauged in flow increments of 10%, the proper size Bean can be easily determined. If, for example, a well flows 100 barrels through a given size ‘X’ bean, the next larger or smaller ‘X’ Bean will result in approximately a 10% increase or decrease, whichever is desired. This is not possible with beans drilled in fractional increments of 1/64”.

TO ORDER TC-575 INSERTS

Select ‘X’ size from circular chart. Use Base Part Number (Prefix) - J090569 + ‘X’ size (Suffix).J090508-001 Bean Gasket required.

PNEUMATIC ADAPTER ASSEMBLIES

AUTOMATION AND REMOTE CONTROL DEVICES AVAILABLEPneumatically Operated ChokesPneumatic actuators can be used to regulate flow (water, oil and gas) or can be used as safety valves. An adapter allows a diaphragm actuator to be incorporated, used with either air or gas. When automation or remote control is desired, a process controller is used to change pressure behind the diaphragm, which operates the choke, regulating the flow rate.

Two types of mounting brackets are available horizontal and vertical. Our standard mounting is vertical (in line with yoke hub) which has distinct advantages:

• In some working pressures and sizes, the actuator is large and heavy, which can make it difficult to change the stem and seat in the choke. With vertical mounting it is not necessary to remove the actuator to change the choke trim. Disconnection of the linkage is the only requirement.

• The vertical-mounted actuator takes up less room, an advantage on offshore platforms and other applications.
