2. Hydrogen compressor - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_compressor

   Hydrogen compressors are closely related to hydrogen pumps and gas compressors: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of hydrogen gas, whereas the main result of a pump raising the pressure of a liquid is to allow the liquid hydrogen to be transported elsewhere.

3. Maximum allowable operating pressure - Wikipedia

   en.wikipedia.org/wiki/Maximum_allowable...

   Maximum Allowable Operating Pressure (MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula , which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...

4. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   The most common ion gauge is the hot-cathode Bayard–Alpert gauge, with a small ion collector inside the grid. A glass envelope with an opening to the vacuum can surround the electrodes, but usually the nude gauge is inserted in the vacuum chamber directly, the pins being fed through a ceramic plate in the wall of the chamber. Hot-cathode ...

6. Liquefied petroleum gas - Wikipedia

   en.wikipedia.org/wiki/Liquefied_petroleum_gas

   Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene , butylene , and isobutylene / isobutene .

7. Inch of mercury - Wikipedia

   en.wikipedia.org/wiki/Inch_of_mercury

   Inches of mercury is also used in automotive cooling system vacuum test and fill tools. A technician will use this tool to remove air from modern automotive cooling systems, test the system's ability to hold vacuum, and subsequently refill using the vacuum as suction for the new coolant. Typical minimum vacuum values are between 22 and 27 inHg.

8. Gas duster - Wikipedia

   en.wikipedia.org/wiki/Gas_duster

   A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.

9. Gas stove - Wikipedia

   en.wikipedia.org/wiki/Gas_stove

   A gas stove is a stove that is fuelled by flammable gas such as natural gas, propane, butane, liquefied petroleum gas or syngas. Before the advent of gas, cooking stoves relied on solid fuels, such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836.
