What is Electrical Heat Tracing (nVent Raychem)?
What is Electrical Heat Tracing(EHT)? Electrical Heat Tracing is an engineered system designed to maintain or protect process piping, equipment, vessels, and instruments at defined temperatures and within the specified design criteria. Electric cables are used for trace heating and to maintain temperature of non-flowing fluids by replacing the heat lost through thermal insulation on pipes, vessels and associated equipment. A self-regulating polymer... Read More
What is Explosion Proof (Ex-Proof)?
What Is Explosion Proof? The concept of explosion proof does not mean a product can withstand any external explosion. For a product, such as explosion proof junction boxes to be classified as explosion proof it would have to be able to contain any explosion originating within the housing due to any sparks from within and prevent igniting vapours, gases, dust or fibres in the air surrounding it. For safety reasons, when equipment is based in hazardous areas, it ... Read More
What are self-regulating heating cables
Introduction Self-regulating heating cables are easier to use and implement as compared to other heat-tracing technologies. They incorporate a heating element that is made up of a polymer core and two parallel conductors. As the surrounding atmospheric temperatures around the cable decreases, the conductive core contracts on a microscopical level, decreasing the electrical resistance and creating numerous electrical paths between the conductors and when electrici...

Different approaches to explosion protection in hazardous areas
Introduction There are various methods to greatly reduce the risk of an explosion happening in hazardous areas. The key objective of these methods is to remove one (or more) components from the “Fire Triangle” and to prevent an explosion from occurring. The fire triangle as per below shows the 3 components needed for combustion and to prevent an explosion, these 3 components must not exist near each other. Source: https://www.safeopedia.com/defin...
