Seal Types

In seal and O-ring design, three considerations are typically examined thermal mechanical, viscoelastic, and incompressibility [14], Thermal mechanical is basically the material changes that we have been discussing under load. Incompressibility is exhibited when a material has an isochoric (zero volume) change under pressure. If [Pg.125]

Gas Holders Gas is sometimes stored in expandable gas holders of either the hquid-seal or dry-seal type. The hquid-seal holder is a familiar sight. It has a cylindrical container, closed at the top, and varies its volume by moving it up and down in an annular water-filled seal tank. The seal tank may be staged in several lifts (as many as five). Seal tanks have been built in sizes up to 280,000 m (10 X lO fE). The dry-seal holder has a rigid top attached to the sidewalls by a flexible fabric diaphragm which permits it to move up and down. It does not involve the weight and foundation costs or the hquid-seal holder. Additional information on gas holders can be found in Gas Engineers Handbook, Industrial Press, New York, 1966. [Pg.1019]

Caution Due to the permissible tolerance on the outside diameter immediately behind the tubing upset, the user is cautioned that difficulties may occur when wraparound seal-type hangers are installed on tubing manufactured on the high side of the tolerance therefore, it is recommended that the user select the joint of tubing to be installed at the top of the string. [Pg.1246]

For windings immersed in either hydrocarbon oil or synthetic liquids the coil insulation is usually a Class A material. For oil-immersed transformers BS 171 specify two maximum oil temperatures 60°C for sealed-type transformers for those fitted with conservators and 55°C for transformers without either. In the case of air-insulated, air-cooled transformers, the class of insulation used, i.e, limits the maximum permitted temperature rise ... [Pg.215]

Focusing on the concept of the completely sealed system, the Sanyo Electric Co. developed sealed-type nickel-cadmium batteries in 1961. This type of battery enjoys a wide application range that is still expanding a large variety of nickel-cadmium batteries has been developed to meet user needs ranging from low-current uses like emergency power sources and semiconductor memories to high-power applications such as cordless drills. [Pg.23]

For many years, sintered-nickel electrodes have been used as the positive electrodes for sealed-type nickel-cadmium batteries. With an increase in the demand for high energy density, this type of elec-... [Pg.26]
