Shenzhen Petersburg Composite Materials Co., Ltd

This product is a high-temperature glass fiber sealing tube for industrial use. It is made of high-strength alkali-free glass fiber yarn through a special weaving process. It has a smooth and soft surface and has excellent heat resistance, flame resistance, corrosion resistance and electrical insulation performance. The product does not contain asbestos and fully meets the high standards of modern industry for environmental protection and safety. It is a high-quality new insulation and protection product that replaces traditional asbestos materials. Its superior performance makes it widely used in various high-temperature sealing, thermal insulation protection, electrical insulation and corrosion resistance environments. The sealed tube can operate stably in a continuous high-temperature environment, and the temperature range can usually reach 550℃. It can withstand higher peak temperatures for a short time and is suitable for high heat load systems such as boilers, heating pipes, industrial furnaces, combustion systems, etc. The product uses Class A non-combustible materials, which will not burn or melt when exposed to fire, effectively blocking the spread of flames and improving the overall fire protection ability of industrial systems. At the same time, it has good chemical corrosion resistance, can resist the erosion of acids, alkalis, oils, solvents and various industrial chemicals, and is suitable for long-term use in harsh working conditions without deformation or degradation. In terms of mechanical properties, the glass fiber sealing tube has strong flexibility and excellent tensile strength. It is suitable for wrapping irregularly shaped parts or equipment structures, and is easy to construct and install. It has outstanding aging resistance, and is resistant to ozone, UV rays, and climate change. Even if it is used for a long time outdoors or in a high temperature and humid environment, it will not become brittle, crack, or perform attenuated. The low shrinkage rate ensures that the sealing state remains stable during long-term operation without loosening, warping, or collapse. It is widely used in the following industrial scenarios: • High-temperature sealing and thermal insulation protection for boilers, furnaces, and industrial heating equipment, used for thermal insulation filling at pipe interfaces, equipment gaps, and high-temperature joints; • Surface coating of equipment such as valves, pump bodies, and chimneys to reduce heat loss, improve system energy efficiency, and protect the surface of the equipment from high temperature and chemical corrosion damage; • It can be used as the basic component of fire curtains, fire ropes, and flame-retardant barrier materials, and plays a key role in fire control and high-temperature partition systems; • It is suitable for high-temperature groove filling, gasket processing, and the outer insulation layer of thermal reactors or equipment. It is an indispensable key material in high-temperature sealing and protection projects. This product is widely used in power equipment manufacturing, thermal energy engineering, metallurgy, petrochemical, mechanical equipment, shipbuilding, glass manufacturing, new energy and other industries. It is a reliable choice for thermal protection and sealing in high-standard industrial applications.
