PRESSURE VESSELS
Air receiver tanks and other pressure containing vessels such as, but
not limited to, pulsation bottles, heat exchangers, moisture separators
and traps, shall be in accordance with ASME Boiler and Pressure Vessel
Code Section VIII and ANSI B19.3 Safety Standards.
MANUAL RELIEF AND SHUTOFF VALVES
Install a manual relief valve to vent the compressor to atmosphere. In
those instances where the air receiver tank services a single compressor,
the manual relief valve can be installed on the receiver. When a manual
shut- off valve, and a safety relief valve installed upstream from the
manual relief valve. These valves are to be designed and installed as to
permit maintenance to be performed in a safe manner. Never substitute
a check valve for a manual shut-off valve (block valve) if the purpose is to
isolate the compressor from a system for servicing.
CAUTION
ASME coded pressure vessels must not be modified, welded, repaired,
reworded or subjected to operation conditions outside the nameplate
ratings. Such actions will negate code status, affect insurance status
and may cause severe personal injury, death, and property damage.
DANGER
Safety valves are to protect system integrity in accordance with ASME
Codes & ANSI B19.3 safety standards. Failure to use safety valves of
the proper capacity and pressure will cause severe personal injury or
death.
DANGER
Failure to properly size, set & install pressure relief valves can be fatal.
CAUTION
Relieve compressor and system air pressure by opening the appropri-
ate manual relief valve prior to servicing. Failure to relieve all system
pressure may result in severe personal injury, death & property damage.
