What are Sealing Fittings?

Sealing fittings, also known as explosion-proof fittings, are devices that prevent the ignition of hazardous substances in electrical equipment. These fittings are designed to contain any explosion or fire within the fitting, preventing it from spreading to other areas. They are commonly used in hazardous locations where there is a risk of explosion or fire.

Types of Hazardous Locations

There are several types of hazardous locations, including Class I, Class II, and Class III locations. Class I locations are areas where flammable gases or vapors are present, while Class II locations are areas where combustible dust is present. Class III locations are areas where ignitable fibers or flyings are present.

Class I Locations

In Class I locations, sealing fittings must be able to prevent the ignition of flammable gases or vapors. These fittings must be able to contain any explosion or fire within the fitting, preventing it from spreading to other areas. Sealing fittings must also be able to withstand the pressure and temperature changes that occur during an explosion or fire.

Class II Locations

In Class II locations, sealing fittings must be able to prevent the ignition of combustible dust. These fittings must be able to contain any explosion or fire within the fitting, preventing it from spreading to other areas. Sealing fittings must also be able to withstand the pressure and temperature changes that occur during an explosion or fire.

Class III Locations

In Class III locations, sealing fittings must be able to prevent the ignition of ignitable fibers or flyings. These fittings must be able to contain any explosion or fire within the fitting, preventing it from spreading to other areas. Sealing fittings must also be able to withstand the pressure and temperature changes that occur during an explosion or fire.

Methods for Sealing Fittings

There are several methods used to seal fittings in hazardous locations, including compound-filled seals, explosion-proof enclosures, and flameproof enclosures.

Compound-Filled Seals

Compound-filled seals are used to seal fittings in Class I locations. These seals consist of a fitting and a compound that fills the space between the fitting and the enclosure. The compound is designed to prevent the ignition of flammable gases or vapors by containing any explosion or fire within the fitting.

Explosion-Proof Enclosures

Explosion-proof enclosures are used to seal fittings in Class I and Class II locations. These enclosures are designed to contain any explosion or fire within the enclosure, preventing it from spreading to other areas. Explosion-proof enclosures are made of materials that can withstand the pressure and temperature changes that occur during an explosion or fire.

Flameproof Enclosures

Flameproof enclosures are used to seal fittings in Class I, Class II, and Class III locations. These enclosures are designed to prevent the ignition of hazardous substances by containing any explosion or fire within the enclosure. Flameproof enclosures are made of materials that can withstand the pressure and temperature changes that occur during an explosion or fire.

Conclusion

Sealing fittings are essential components in hazardous locations where flammable gases, vapors, or dust particles are present. These fittings protect electrical equipment from explosions and fires by preventing the ignition of hazardous substances. There are several types of hazardous locations, including Class I, Class II, and Class III locations. Sealing fittings can be sealed using compound-filled seals, explosion-proof enclosures, and flameproof enclosures. It is important to choose the right sealing method for the type of hazardous location and to ensure that the sealing fittings are properly installed and maintained.
