Haotian Brand High-Temperature Resistant Coupling SleevesFeatures and Applications
1.Safe and environmentally friendly, protecting workers' health
Alkali-free fiberglass has excellent tensile strength, does not wrinkle or break, is resistant to vulcanization, smoke-free, halogen-free, non-toxic, non-flammable in pure oxygen, and has good insulation properties. After being cured with organic silicone, its safety and environmental protection performance is further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike products made from asbestos, which pose significant hazards to human health and the environment.
2.Excellent high-temperature resistance
The surface of the high-temperature sleeve contains both 'organic groups' and 'inorganic structures' in its silicone structure. This special composition and molecular structure combine the characteristics of organic materials with the functions of inorganic materials. Compared with other polymer materials, its most notable feature is its high-temperature resistance. With a main chain structure based on silicon-oxygen (Si-O), the bond energy of C-C bonds is82.6 kcal/mole, while the bond energy of Si-O bonds in organosilicon is121 kcal/mole, hence its high thermal stability; at high temperatures (or under radiation), the chemical bonds of the molecules do not break or decompose. Organosilicon not only withstands high temperatures but also low temperatures, and can be used over a wide temperature range. Both its chemical and physical mechanical properties change very little with temperature.
3.Splash-proof, multi-layer protection
In the smelting industry, the medium temperature inside electric furnaces is extremely high, easily leading to high-temperature splashes (the same is true in the welding industry), which upon cooling and solidifying can form slag on pipes or cables, causing the rubber on the outer layer of the pipes or cables to harden and eventually become brittle and crack. This can damage unprotected equipment and cables. The high-temperature sleeve, coated with multiple layers of silicone, provides multiple safety protections, with a high-temperature resistance of up to 1300 degrees Celsius, effectively blocking splashes of molten iron, molten copper, molten aluminum, and other high-temperature molten materials, preventing damage to surrounding cables and equipment.
4.Insulation and heat preservation, energy saving and consumption reduction, radiation resistance
In high-temperature workshops, many pipes, valves, or equipment have very high internal temperatures. Without protective materials, this can easily lead to personnel burns or heat loss. Haotian high-temperature sleeves have better thermal stability than other polymer materials, as well as radiation resistance and insulation properties, preventing accidents and reducing energy consumption. They also prevent the heat of the medium inside the pipes from being directly transferred to the surrounding environment, which can cause excessive workshop temperatures and save cooling costs.
5.Moisture-proof, oil-proof, resistant to weather aging, pollution, extending equipment lifespan
High-temperature sleeves exhibit strong chemical stability, showing no reaction to oil, water, acids, or bases in organosilicon materials, which can be used long-term at temperatures below 260℃, and do not age. Their lifespan under natural conditions can reach decades, maximizing protection for pipes, cables, and equipment in such environments, significantly extending their service life.
6.Ozone-resistant, voltage-resistant, arc-resistant, and corona-resistant performance
Due to the surface coating of organosilicone, which has a main chain of -Si-O-, the bonds are resistant to decomposition by ultraviolet light and ozone. High-temperature sleeves have excellent electrical insulation properties, with dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity all ranking among the best in insulating materials, and their electrical performance is minimally affected by temperature and frequency. Therefore, they are a stable electrical insulating material widely used in the electronics and electrical industries.
7.Flame retardant, reducing the incidence and spread speed of fire
If the medium transported in the pipes is flammable or toxic, leaks can easily lead to fires or casualties; cables often burn due to localized high temperatures. The high-temperature sleeves are made of extremely heat-resistant woven fiberglass, with the surface silicone added with appropriate flame retardants and other special materials, giving them excellent flame-retardant properties. Even in the event of a fire, they can prevent the spread of flames, protecting the internal pipelines intact for a longer time, providing ample time for the rescue of data and important information.
