Fusible Plugs Fittings

Features 

Eutectic alloy is filled in the stainless steel plug.
◎ For liquid or gas service.
◎ Non-reusable and disassembled pressure relief devices.
◎ Maximum operating pressure: Tested to 500 psig (3.4 MPa)
◎ Temperature rating from 160°F (71°C) to 281°F (138°C) with 4 temperature ranges
◎ Two types of end connections : Pipe threads and tube adapters

Fusible Plugs

Application

Pressure relief devices consisting of the body and the eutectic alloy. Meanwhile the eutectic alloy has a specific melting point. When the plug is exposed to temperatures at or above this melting point, the eutectic alloy will melt and the pressure inside the plug will be released to the atmosphere for protection of systems.
For example, a fitting can be installed on the air supply fine to a normally closed, air-to open valve. In the event of fire consequently the material will melt, Therefore the loss of air pressure. After that the valve automatically will shuts down the flow of the flammable or hazardous fluids in the system.

Cautions

◎ Dimensions are for reference only and are subject to change.
◎ Welding of the same material is more advisable considering the same coefficients of expansion, lower possibility of weld consequently out-of-roundness or dimensional changes.
