2. Acetylene - Wikipedia

   en.wikipedia.org/wiki/Acetylene

   [citation needed] Consequently, acetylene, if initiated by intense heat or a shockwave, can decompose explosively if the absolute pressure of the gas exceeds about 200 kilopascals (29 psi). Most regulators and pressure gauges on equipment report gauge pressure, and the safe limit for acetylene therefore is 101 kPa gage, or 15 psig.

3. Gas cylinder - Wikipedia

   en.wikipedia.org/wiki/Gas_cylinder

   A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...

4. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   More than 1/7 the capacity of the cylinder should not be used per hour. This causes the acetone inside the acetylene cylinder to come out of the cylinder and contaminate the hose and possibly the torch. Acetylene is dangerous above 1 atm (15 psi) pressure. It is unstable and explosively decomposes.

5. Bottled gas - Wikipedia

   en.wikipedia.org/wiki/Bottled_gas

   The general rule is that one unit volume of liquid will expand to approximately 800 unit volumes of gas at standard temperature and pressure with some variation due to intermolecular force and molecule size compared to an ideal gas. Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal ...

6. Industrial gas - Wikipedia

   en.wikipedia.org/wiki/Industrial_gas

   A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.

7. MAPP gas - Wikipedia

   en.wikipedia.org/wiki/MAPP_gas

   A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.

8. Orders of magnitude (pressure) - Wikipedia

   en.wikipedia.org/wiki/Orders_of_magnitude_(pressure)

   120–290 psi Pressure used in boilers of steam locomotives [citation needed] 1.1 MPa 162 psi Pressure of an average human bite [citation needed] 2.8–8.3 MPa 400–1,200 psi Pressure of carbon dioxide propellant in a paintball gun [64] 5 MPa 700 psi Water pressure of the output of a coin-operated car wash spray nozzle [58] 5 MPa 700 psi

9. Pound per square inch - Wikipedia

   en.wikipedia.org/wiki/Pound_per_square_inch

   In SI units, 1 psi is approximately 6,895 pascals. The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around 14.7 psi (101 kilopascals), this will be added to any pressure reading made in air at sea ...
