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 ...
The endurance of the cylinder can be calculated from the volume, pressure and breathing rate of the user. The formula: volume (in liters) × pressure (in bars) / 40 (litres per minute) - 10 minutes (the 10 minutes is a safety margin, or reserve), so a 6-liter cylinder, of 300 bar, is 6 × 300 / 40 - 10 = 35 minutes working duration.
The American Standard Safety System, or ASSS, is a connection system for gas cylinders with a volume exceeding 25 cubic feet. The connections differ in thread type and size, right and left-handed threading, internal and external threading, and nipple-seat design.
These common US standard gas cylinders have the following requirements: [4] DOT-3AL gas cylinders must be tested every 5 years and have an unlimited life. DOT-3HT gas cylinders must be tested every 3 years and have a 24-year life. DOT-3AA gas cylinders must be tested every 5 years and have an unlimited life.
The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source (usually contained in cylinders), two pressure regulators and two flexible hoses (one for each cylinder), and a torch. This sort of torch can also be used for soldering and brazing. The cylinders are often carried in a special wheeled trolley.
The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.
After a cylinder passes the test, the test date, (or the test expiry date in some countries such as Germany), is punched into the shoulder of the cylinder for easy verification at fill time. [note 1] The international standard for the stamp format is ISO 13769, Gas cylinders - Stamp marking. [1]
The range of available connection standards covers the majority of the range of industrial, ultra-pure and medical gases in use, including the medical pin index safety system, scuba cylinder valves and liquefied natural gas for home use. [5] The standards include: CGA V-1 Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections [5]
