Air receivers are tanks used for compressed air storage and are recommended to be in all compressed air systems. Using air receivers of unsound or questionable construction can be very dangerous. Therefore, the American Society of Mechanical Engineers (ASME) has developed a code regarding the construction of unfired pressure vessels, which has been incorporated into many federal, state, and local laws. This particular code is ASME Code Section VIII Division 1. Air receivers should always meet or exceed this code in addition to any other state, municipal, or insurance codes that may apply.
