Typically, oil / gas rigs, oil refineries, chemical production facilities, flammable liquid storage facilities, fuel transportation, gas stations, paint production, and papermaking sites are classified as hazardous areas. Defined as an area in the atmosphere that contains or may contain a sufficient amount of flammable or explosive gases, dust or steam.
In such an atmosphere, if three basic conditions are met, a fire or explosion may occur. It is often referred to as a "hazardous area" or "burning" triangle (as shown on the right).
To protect equipment from potential explosions, a method of analyzing and classifying potentially hazardous areas is needed.
The purpose is to ensure the correct selection and installation of equipment to ultimately prevent explosions and ensure life safety. The method used to classify the installation may vary, depending on the region where the installation is located, but there are generally two main types of classification.
In countries that adopt the IEC (International Electrotechnical Commission) concept, this is called zoning, while in North America it is categorized by category, zoning, and group to determine the required security level.
In order to adapt to this special application environment, EATON, a British explosion-proof cable gland expert, has customized a series of related products: explosion-proof thread adapters, such as explosion-proof and increased safety thread adapters, reducers, wire plugs, breathing joints and others Accessories such as nuts, grounding rings, IP seals, serrated washers, etc.
Standards and certifications: According to various standards such as international, European, North American, Russian and other standards, and obtained a variety of certifications such as IECEx, ATEX, CSA and GOST.
Thread : ISO metric system, NPT system, NSP system, ISO pipe thread BSP system, PG system and ET system.
Material: Brass, nickel-plated brass, stainless steel 316, aluminum, carbon steel, tempered nylon with 30% glass fiber, etc.
Industry-specific: Typical users of these products include oil or gas operation platforms, oil and petrochemical companies, engineering contractors, and other manufacturers of equipment in hazardous areas.
Prevent damage to industrial and commercial electrical equipment, ensure uninterrupted power supply, and help stabilize the power grid.
This function is achieved through the operation and use of industrial fuses and all related accessories (to prevent short circuits) and surge protectors (to prevent damage caused by surges).
