New and Existing Equipment
Air receivers (compressed air tanks) should be built according to the A.S.M.E. Boiler and Pressure Vessel Code. All safety valves used must be constructed, installed and maintained according to the A.S.M.E. Boiler and Pressure Vessel Code.
Installation and Equipment Requirements
All drains, handholes and manholes should be easily accessible. Air receivers should not be buried underground or located in an inaccessible place. Every air receiver should have a drain pipe and valve installed at its lowest point to allow for the removal of any accumulated oil or water. Air receiver drain valves should be opened frequently (per manufacturer’s recommendations) to remove excessive amounts of oil or water.
Air receivers should be equipped with pressure gauges and safety valves that are readily visible and easily accessible. The total relieving capacity of the safety valve should be enough to prevent pressure in the receiver from exceeding the maximum allowable working pressure of the receiver by more than ten percent. Safety valves should be tested frequently and at regular intervals to assure they remain in good operating condition.
