An explosion-proof gland is an explosion-proof accessory used with cables that require high standards; it can be installed at the connection point between the explosion-proof cable connector and the explosion-proof electrical equipment. It serves to introduce the cable and secure it in place, thereby achieving sealing and explosion protection. It boasts advantages such as excellent explosion protection performance, a safe and reliable structure, simple and easy installation, and a high level of protection. It is widely used in various fields such as petroleum and chemicals where electrical safety and explosion prevention are required, especially in offshore platforms and ships where electrical explosion prevention is essential. The difference between explosion-proof flanges and ordinary flanges: It’s actually not difficult to distinguish between the two. First: Explosion-proof flanges are made of metal, with stainless steel, carbon steel, or brass being the common materials used. While the regular Gran head is made of plastic. Second: The explosion-proof gland is equipped with explosion-proof certification, test reports, and 3C certificates; it possesses explosion-proof capabilities, offering greater professionalism and reliability. Ordinary Gran heads do not have these documents. Third: Ordinary flange heads are inexpensive, while explosion-proof flange heads have higher costs and are thus more expensive as well. Fourth: The industries in which they are used are also different. The standard gland is suitable for use in ordinary distribution boxes, switchgear cabinets, control boxes, and distribution panels; it is used to secure lighting wires and cables, providing effective clamping while also serving as a waterproof seal. Explosion-proof gland fittings are suitable for explosion-proof equipment such as explosion-proof distribution boxes and explosion-proof instrument panels; they are mostly used in chemical enterprises, and their primary functions are to provide explosion protection, isolation, and sealing. After explaining the four differences between the two most important types in detail, let’s talk about their common function, which is to provide sealing and clamping. Ordinary flange connectors offer protection against water and dust, while explosion-proof flange connectors, in addition to having those same advantages, also provide protection against explosions and corrosion; they are generally used in explosion-proof equipment. So, to determine whether it is an explosion-proof fitting, first check if it is made of metal; secondly, the most straightforward way is to look for an “Ex” marking on the fitting itself. Regardless of the type of threaded connection, in special industries where there is a risk of fire, explosion, or environmental corrosion, high-end, high-quality threaded connections are required, such as explosion-proof threaded connections made of 304 or 316 stainless steel.
