Fire is a serious disaster, which not only poses a threat to human life and property safety, but also brings huge damage to the environment. In order to reduce the harm of fire to people and property, fire casing, as an important protective device, is being widely used in various industries. This article will introduce the definition, function and application of fire protection bushing in different fields.
1. What is fire casing? A fire sleeving, also known as a fire sleeve, is a tubular device made of high temperature and abrasion resistant materials. It is usually composed of multiple layers of materials, each layer has a different function, such as flame retardancy, heat insulation and corrosion resistance, etc. The fireproof casing can effectively resist the spread of flame and the erosion of high temperature, providing important protection for personnel and property.
2. The function of the fire casing:
1. Prevent the spread of fire: the fireproof casing can effectively isolate and prevent the entry of external flames and high temperatures, preventing the spread and expansion of fire. It can quickly cut off the fire, delay the speed of fire spread, and gain valuable time for personnel evacuation and fire fighting.
2. High temperature protection: In a high temperature environment, the fire casing can effectively separate the heat source and protect personnel and equipment from high temperature. It can absorb and dissipate heat, reduce heat conduction, reduce heat radiation to personnel, and provide a safer working environment.
3. Maintenance of protective equipment: Fireproof casing can also protect all kinds of protective equipment from damage by external factors and prolong their service life. For example, the use of fire-resistant sleeves at the welding site can effectively reduce the damage to protective clothing, gloves and other protective equipment caused by spatter, and ensure their normal use.
3. The wide application of fire casing:
1. Industrial field: Fireproof casing is widely used in the protection of pipelines, cable lines and other facilities in chemical industry, electric power, metallurgy and other industries. They can effectively prevent the occurrence of fire accidents and improve the safety of the work site.
2. Construction field: In the installation of wires and cables in buildings, fireproof sleeves are necessary protective equipment. It can effectively isolate the contact between the cable line and the fire source, reduce the risk of fire and ensure the safety of the building.
3. Automobile industry: Fireproof bushings are widely used in the protection of automobile wire and cable systems to prevent fires caused by electrical faults in vehicles and ensure the personal safety of passengers.
