This industrial-grade fiberglass sealing tube is made of high-strength fiberglass yarn, which is precisely woven to provide an environmentally friendly, efficient and long-term stable solution, completely replacing traditional asbestos-based materials. It is designed for sealing and insulation needs in high temperature, high pressure and harsh environments. It has excellent thermal stability and fire resistance, and can operate stably in environments with temperatures up to 800°C, ensuring long-term use is not affected. With its excellent thermal insulation performance, the sealing tube effectively reduces heat conduction, reduces equipment temperature, saves energy and reduces consumption, while providing lasting protection for the equipment. One of the biggest features of this product is its excellent fireproof performance. It is made of Class A non-combustible materials and can resist the spread of flames under extreme high temperature conditions to ensure the safety of the system. In addition, the sealing tube also has excellent chemical stability and can withstand erosion by corrosive chemicals such as acids, alkalis and salts. Its ozone resistance, UV resistance and aging resistance enable it to maintain its original performance after long-term exposure to the external environment, avoid material aging and performance degradation, and have a longer service life. In terms of mechanical strength, this fiberglass sealing tube has undergone multiple strengthening treatments and has strong tensile, tear and fatigue resistance. Even under extreme operating conditions such as vibration and compression, it can still maintain the sealing effect without deformation, shrinkage or cracking. Its low shrinkage characteristics allow the sealing tube to maintain its shape after long-term use, ensuring a long-lasting sealing effect. The sealing tube is widely used in various equipment and systems that require high temperature, sealing and thermal insulation protection. Common applications include sealing gaps between boiler units and furnace walls to prevent heat leakage; thermal insulation protection of chimneys, valves, pumps and heat exchangers to avoid heat loss; gasket materials for pipeline channels to ensure the normal transfer of heat flow; and the use of fire curtain ropes and high-temperature hoods to protect key equipment from flames and heat. Applicable industries cover many fields such as metallurgy, electricity, petrochemicals, steel, thermal energy, and machinery manufacturing, especially boilers, petrochemical equipment, industrial furnaces, power plants, pipeline transportation and fire protection systems, which can effectively improve the safety, stability and energy efficiency of the system. The excellent performance and flexibility of this fiberglass sealing tube make it an ideal choice for reliable use in extreme environments. It is an indispensable functional sealing and thermal insulation material in various high-temperature industrial applications.
