Circulating sleeve

The figure on the right shows the well with a simple well completion including a production tubing with packer, a series of surface safety valves called a Christmas tree, a subsurface safety valve (SSSV), a circulating sleeve, and a series of perforations through the casing.

Fig. 5. The gas flow path of an AGR. Note the flow is reentrant, i.e., a fraction of the coot gas from the circulator flows up around the outside of the core entering the core from the top, then flows downward through the core, between the moderator and fuel element assembly, to the bottom where it mixes with the cool gas from the circulator and flows up the fuel channel inside the graphite fuel sleeves to the steam generators.

Rubber Sleeve Core Barrels. Rubber sleeve core barrels are special application tools designed to recover undisturbed core in soft, unconsolidated formations. As the core is cut, it is encased in the rubber sleeve that contains and supports it. Using face discharge ports in the bit, the contamination of the core by circulating fluid is reduced. The rubber sleeve core barrel has proven to be a very effective tool, in spite of the fact that the rubber sleeve becomes weak with a tendency to split as the temperature increases about 175°F. 

For MTHW and HTFIW systems, heat emitters may be as for LTFIW systems, except that, for safety reasons, units with accessible surfaces at water temperature would not normally be employed. Embedded panel coils may be used in conjunction with a MTHW or HTHW distribution system, with insulating sleeves around the coil piping to reduce the heat flow. Alternatively, the coils can be operated as reduced temperature secondary systems by allowing only a small, carefully controlled proportion of flow temperature water to be mixed with the water circulating in the coils. 

The energy is transferred to the glass inner surface of the condenser. We maintain a cool temperature inside the condenser by running a constant flow of water through the condenser s jacketed sleeve. The solvent releases a large amount of heat energy as it converts back to liquid, which passes to the water circulating within the jacket, and is then swept away. 

The graphite rod behaves like an ohmic resistor when it is subjected to a potential difference of a few volts. The rod is surrounded by a double sleeve containing an inert gas to protect it from oxidation and allow circulating water to cool the assembly. To avoid splashing, the temperature is gradually increased to first dry, then calcify and finally atomise the sample. The available thermal power is sufficient to reproducibly atomise the sample into the gas phase within three or four seconds (Fig. 14.9). 

Nitration vessels are usually equipped with one of three general types of agitating mechanism (1) single or double impeller, (2) propeller or turbine, with cooling sleeve, and (3) outside tunnel circulation. 

The term sleeve-and-propeller agitation is usually applied when the nitration vessel is equipped with a vertical sleeve through which the charge is circulated by the action of a marine propeller or turbine. The sleeve is... 

In one series oxygen gas was circulated through a quartz sleeve which surrounded the lamp for its full length hence the radiation had to pass through the lamp walls... 

The graphite tube is surrounded by a double sleeve. One contains an inert gas, such as argon, that circulates to protect the elements from oxidation while the other cools the entire device, using water. 

Water is circulated through the specimen, confined within a Viton sleeve, and pressurized by the confining fluid within the core holder. Flow rates are prescribed. 

Liquid silicone rubbers have also been used in some extruded applications. Vulcanization of the extruded material may be carried out by using infrared heaters or circulated hot air. The process has been applied to wire coating, ignition cables, optical fibers, various tapes, and braided glass-fiber sleeving, as well as for covering delicate products. 

Total immersion of the module with water and water circulation. The module is in horizontal position to allow complete immersion of the sleeves.
