Gas holder — A gasometer, or gas holder, is a large container where natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a… … Wikipedia
Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… … Wikipedia
Gas cylinder — For the mechanical devices used to impart a force from a pressurized liquid or gas, see pneumatic cylinder. For the large structures used to store town gas, see gas holder. Industrial compressed gas cylinders used for oxy fuel welding and cutting … Wikipedia
Pressure cooking — is a method of cooking in a sealed vessel that does not permit air or liquids to escape below a preset pressure. Because the boiling point of water increases as the pressure increases, the pressure built up inside the cooker allows the liquid in… … Wikipedia
Seal (mechanical) — Compression seal example A mechanical seal is a device which helps join systems or mechanisms together by preventing leakage (e.g., in a plumbing system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent… … Wikipedia
Gas meter prover — A Gas Meter Prover is a piece of equipment used to verify the accuracy of a gas meter. Presently, gas meter provers (or more simply “provers”) refer to manually or electronic and/or computer controlled equipment used to calculate accuracy of a… … Wikipedia
Gas syringe — A gas syringe also known as glass collecting bottle, is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to measure the volume of gas evolved from a chemical reaction. A gas syringe can also be … Wikipedia
Gas spring — A gas spring is a type of spring that, unlike a typical metal spring, uses a compressed gas, contained in a cylinder and variably compressed by a piston, to exert a force. Gas springs are used frequently in automobile construction, where they are … Wikipedia
gas reservoir — In geology, a naturally occurring storage area, characteristically a folded rock formation, that traps and holds natural gas. The reservoir rock must be permeable and porous to contain the gas, and it has to be capped by impervious rock in order… … Universalium
Gas check — A gas check is a device used in some types of firearms ammunition. Gas checks are used when non jacketed bullets are used in high pressure cartridges, to prevent the buildup of lead in the barrel and aid in accuracy.cite web… … Wikipedia
Dry gas seal — Dry gas seals are non contacting, dry running mechanical face seals consist of a mating (rotating) ring and a primary (stationary) ring. When operating, grooves in the rotating ring generate a fluid dynamic force causing the stationary ring to… … Wikipedia
