2. Surge control - Wikipedia

   en.wikipedia.org/wiki/Surge_control

   A highly accurate and reliable approach to controlling the nitrogen pressure on a gas-loaded surge relief valve is to use an electronic control system to add and vent nitrogen pressure from the gas-loaded surge relief valve. This technique assures the required set point accuracy and repeatability needed in this critical application.

3. Tank blanketing - Wikipedia

   en.wikipedia.org/wiki/Tank_blanketing

   Since most blanketing gas sources will provide gas at a much higher than desired pressure, a blanketing system will also use a pressure reducing valve to decrease the inlet pressure to the tank. Although it varies from application to application, blanketing systems usually operate at a slightly higher than atmospheric pressure (a few inches of ...

4. Vacuum insulated evaporator - Wikipedia

   en.wikipedia.org/wiki/Vacuum_insulated_evaporator

   A vacuum insulated evaporator (VIE) is a form of pressure vessel that allows the bulk storage of cryogenic liquids including oxygen, nitrogen and argon for industrial processes and medical applications. [1] The purpose of the vacuum insulation is to prevent heat transfer between the inner shell, which holds the liquid, and surrounding ...

5. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection , and pressurization of the vessel to the specified ...

6. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   The inlet pressure gauge will indicate this pressure. The gas then passes through the normally open pressure control valve orifice and the downstream pressure rises until the valve actuating diaphragm is deflected sufficiently to close the valve, preventing any more gas from entering the low pressure side until the pressure drops again.

7. Tracer-gas leak testing - Wikipedia

   en.wikipedia.org/wiki/Tracer-gas_leak_testing

   A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.

9. Liquefaction of gases - Wikipedia

   en.wikipedia.org/wiki/Liquefaction_of_gases

   Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG, and in refrigeration and air conditioning.
