Fusible Plug

Fusible Plug. Air type fusible plugs are used to protect compressed air systems from the risk of an explosion occurring due to ignition of oil vapours in compressors and compressed air systems Boiler type fusible plugs are used to protect solid fuel fired boilers from being operated at dangerously low water levels Both plugs are designed to operate when high temperatures occur thereby reducing pressure and providing audible warning of dangerous conditions.

Fusible plugs are a type of warning device employed on compressed air systems well heads and steam systems They are considered a last line of defense and are often used to avert a catastrophic failure occurring eg explosion Whist safety valves protect machinery items from over pressure fusible plugs protect machinery items from over temperature.

Fusible plug occasionally also called safety plug fuse plug solder plug or melt fuse is thermally operated nonreclosing pressure relief devices to function by the yielding or melting of the fusible alloys sintered in the plug body Fusible plugs only respond to overtemperature Compared to other type of safety devices they are simpler and require no maintenance.

A fusible plug is a threaded metal cylinder usually of bronze brass or gunmetal with a tapered hole drilled completely through its length This hole is sealed with a metal of low melting point that flows away if a predetermined high temperature is reached The initial use of the fusible plug was as a safety precaution against low water levels in steam engine boilers but later applications extended its use to other closed vessels such as air conditioning systems and tanks for transporting c.
