1. Tensile strength: This seal has high tensile strength, and its value can reach ≥12 MPa. This allows it to maintain structural integrity when facing the tensile force generated during the opening and closing process of the valve, and is not prone to rupture or damage, effectively adapting to the working requirements of frequent valve operations.

2. Tear strength: It has a tear strength of ≥25 kN/m. During the mechanical movement of the valve, even if it is subject to local stress concentration or unexpected external force impact, it can effectively resist tearing and ensure the overall structure of the seal. Stable and maintain good sealing effect.

3. Compression permanent deformation performance: After 22 hours of compression test in a high temperature environment of 200°C, the compression permanent deformation rate is ≤30%. This means that when the valve is closed and under pressure, the seal can provide continuous and stable sealing force, and can quickly return to its original shape and performance after the pressure is released, ensuring reliable sealing of the valve after multiple opening and closing cycles. properties, reducing the risk of leakage due to reduced seal performance.

1. Distillation tower valves: During the crude oil distillation process, the valves of the distillation tower need to accurately control the entry and exit of fractions with different boiling points. FKM80 seals can ensure leak-free operation of valves in harsh environments of high temperature, high pressure and contact with a variety of complex hydrocarbon mixtures, ensure the efficiency and accuracy of the distillation process, and improve the quality and yield of distillate products.

2. Catalytic cracking unit valve: Catalytic cracking is one of the core processes of a refinery. The valves in this unit face extreme conditions such as high temperature, oil and gas containing catalyst particles, and frequent pressure fluctuations. The seal here can effectively prevent oil and gas leakage, maintain stable pressure within the device, ensure the continuous and stable progress of the catalytic cracking reaction, and improve the yield and product quality of light oil.

3. Heat exchanger valve: The heat exchanger is used to regulate the flow and temperature of the heat exchange medium during the oil refining process. Since the heat exchange process involves the transfer of high-temperature heat energy, FKM80 seals can withstand the high temperature difference and thermal stress at the inlet and outlet of the heat exchanger, prevent leakage of the heat exchange medium, ensure heat exchange efficiency and the normal operation of the entire system, and reduce energy consumption and production cost.

(1) Long-term sealing guarantee

With its exceptional high temperature, chemical resistance and mechanical properties, FKM80 seals provide reliable sealing over time under the harsh high temperature conditions of refineries. Compared with ordinary seals, it greatly reduces the replacement frequency of valve seals, reduces downtime caused by seal maintenance and replacement, significantly improves the production efficiency of the refinery, and creates greater economic benefits for the enterprise. .

(2) High reliability and safety

In extreme high temperatures and complex chemical environments, FKM80 seals always maintain stable performance, effectively reducing the risk of valve leakage. This is crucial for refineries because leaking valves may cause serious safety incidents such as fires, explosions, and environmental pollution. The use of this seal can protect the safe production of the refinery, protect the lives of employees and the safety of the company's property, and also help companies meet strict environmental regulations.

(3) Broad adaptability

This seal can be adapted to different types, specifications and pressure levels of high-temperature valves in refineries. Whether they are common valve types such as gate valves, globe valves, ball valves or butterfly valves, they can be perfectly matched and provide excellent sealing effects. This provides a one-stop solution for valve sealing in refineries, allowing users to avoid overly considering the compatibility of seals and valves during the selection and application process, simplifying the procurement and installation process, and reducing the difficulty of project implementation. and cost.

(4) Energy saving and environmental protection benefits

Due to its precise sealing performance, FKM80 seals can effectively reduce the leakage of media in the valve and reduce the waste of precious resources such as oil and gas. At the same time, reducing leakage also means reducing greenhouse gas emissions and other environmental problems caused by leakage, which is in line with the strategic requirements of the sustainable development of refineries and helps companies actively fulfill their social responsibilities and improve their corporate image while achieving economic benefits. Social image and competitiveness.

(1) Installation points

1. Before installation, be sure to ensure that the valve sealing surface is clean, smooth, and free of any impurities, oil, or damage. Cleaning and inspection can be done using appropriate cleaners and tools.

2. Carefully check whether the size and specifications of the seal match the valve to avoid affecting the sealing effect or causing installation difficulties due to size discrepancy.

3. During installation, handle gently to avoid overstretching, twisting or scratching the seal. Appropriate installation tools and auxiliary devices can be used to ensure that the seal is installed correctly and smoothly.

4. For parts that need to be sealed, apply an appropriate amount of lubricant that is compatible with the seal and the medium to reduce installation friction and help improve sealing performance. However, it should be noted that the amount of lubricant should not be too much, so as not to affect the sealing effect.

(2) Maintenance suggestions

1. Check the valve and seals regularly to see if the seals show any signs of aging, hardening, deformation, cracking or leakage. The inspection cycle can be determined based on the actual production conditions and equipment operating conditions of the refinery. It is generally recommended to conduct a comprehensive inspection every [X] months.

2. During the inspection, if the seal is found to be slightly damaged or has reduced performance, corresponding maintenance measures can be taken according to the specific situation, such as adjusting the installation position of the seal, replacing partially damaged parts, or performing appropriate repairs on the seal. . However, seals that are severely damaged or have significantly reduced performance should be replaced in time to ensure the sealing performance of the valve and the safe operation of the equipment.
