Features and Applications of Pipeline Fire Protection Sleeves

    Weather aging resistance, pollution resistance, prolonging equipment service life

The service life under natural conditions can reach several decades, maximizing the protection of pipelines, cables, and equipment in these environments, greatly extending their service life.

Ozone resistance, voltage resistance, arc resistance, and corona resistance

Due to the surface coating of silicone, with the main chain being -Si－O－, the bonds are not easily broken by ultraviolet light and ozone. High-temperature protective sleeves have excellent electrical insulation properties, ranking among the best in terms of dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity in insulating materials. Furthermore, their electrical performance is minimally affected by temperature and frequency. Thus, they are a stable electrical insulating material widely used in the electronics and electrical industries.

Superior high-temperature resistance

High-temperature protective sleeves can withstand high temperatures of up to 260℃ without damage. They can endure temperatures as high as 1090℃ for 15 to 20 minutes, and 1650℃ for 15 to 30 seconds. Their unique flame-retardant properties not only effectively prevent personnel from burns due to high-temperature pipelines but also significantly reduce the cost of thermal energy loss.

Unique chemical stability

High-temperature protective sleeves possess strong chemical stability, showing no reaction with oil, water, acids, or bases. They can be used long-term without aging at temperatures below 260℃, and are not easily degraded by ultraviolet light and ozone due to their silicone surface coating.

Splash protection and multiple safeguards

In the smelting industry, the medium temperature inside electric furnaces is extremely high, making it easy to form high-temperature splashes (the same applies to the electric welding industry). After cooling and solidifying, the splashes can form slag on pipelines or cables, causing the rubber outer layer of the pipelines or cables to harden, becoming brittle and cracking. This can damage unprotected equipment and cables. The high-temperature sleeves coated with multiple layers of silicone can provide multiple safety protections, with high-temperature resistance 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.

Safe and environmentally friendly

Alkali-free fiberglass has strong tensile strength, does not wrinkle or break, is resistant to vulcanization, and is smoke-free, halogen-free, and non-toxic. It is pure oxygen non-combustible with good insulation properties. After being cured with silicone, its safety and environmental performance is further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose significant risks to human health and the environment.
