The term air line is also used to describe fixed pipe compressed air systems. These systems are often found in laboratories, workshops, manufacturing facilities & on other sites for industrial processes.

Air line failure is a failure of the tubing which connects the air bags or struts to the rest of the air system, and is typically DOT-approved nylon air brake line. This usually occurs when the air lines, which must be routed to the air bags through the chassis of the vehicle, rub against a sharp edge of a chassis member or a moving suspension ...

For high pressure, flare joints are made by doubling the tube wall material over itself before the bell end is formed. The double flare avoids stretching the cut end where a single flare may crack. Before the flaring step, the end of the tube is compressed axially causing the tube wall to yield radially outward forming a bubble.

The tanks must be designed to safety standards appropriate for a pressure vessel, such as ISO 11439. [7]The pressure vessels or air storage tanks that can be used in compressed-air vehicles can be made of low pressure (9 atm (130 psi)) or high pressure (more than 240 atm (3,500 psi)), and can be made of composite materials like thermoplastic and fiber reinforced thermoplastics, [6] [8] that ...
