However, due to factors such as medium pressure, temperature changes, material aging, as well as incorrect selection and installation, gaskets may leak. Leaks not only lead to waste of energy and materials, but can also pose threats to equipment safety and the environment. Therefore, understanding the causes, manifestations, and solutions for gasket leakage is crucial to ensuring the safety and reliability of equipment operation. I. Reasons for gasket leakage 1. Damaged or aged gaskets: Over time, gaskets are subjected to corrosion, wear, and pressure from the medium they come into contact with, which can cause them to break or age, leading to leakage. 2. Incorrect material selection: Choosing an inappropriate gasket material that is not suitable for the chemical properties, temperature, and pressure of the medium can lead to leaks. 3. Improper installation and tightening: If the tightening force is uneven or insufficient during the installation of the gaskets, leakage can occur. II. Manifestations of gasket leakage 1. Leakage points: Leakage usually results in distinct leakage points around the gasket, which can be identified through visual inspection or instrumental testing. 2. Leakage and dripping: Gasket leakage may manifest as seepage or dripping, which can result in wetness, oil stains, or residues of chemicals on the surface of the equipment. 3. Pressure and temperature changes: Gasket leakage can cause changes in the pressure and temperature of the medium within the equipment, which can be detected through the equipment’s monitoring system or by observation by operators. III. Solutions and Preventive Measures 1. Gasket selection: Choose an appropriate gasket material based on the operating conditions and properties of the medium, to ensure its resistance to chemical corrosion as well as its suitability under varying temperature and pressure conditions. 2. Proper installation and tightening: Ensure that the gaskets are tightened evenly, using the specified torque values, to avoid either over-tightening or under-tightening. 3. Regular inspection and replacement: Regularly check the condition of the gaskets, and promptly identify and replace those that are aged, damaged, or no longer functional. 4. Use auxiliary sealants: For applications that require higher sealing performance, it is possible to consider using auxiliary sealants such as sealants or coatings. Gaskets play an important sealing role in industrial applications, but leakage is a common challenge. Understanding the causes and symptoms of gasket leakage, as well as adopting appropriate solutions and preventive measures, is crucial for ensuring the safe and reliable operation of equipment. Engineers and operators should pay close attention to the condition of the gaskets, carrying out regular inspections and maintenance to ensure their integrity and performance, thereby reducing leakage issues and improving the efficiency and sustainability of the equipment. / Fle*ngSeale PTFE sealing tape / The Fle*ngSeal expanded PTFE sealing material, developed by Chengdu Xinrui Fangxiao Technology Co., Ltd., is an innovative solution that can effectively address gasket leakage issues. It has the following advantages: The Fle*ngSeal expanded PTFE sealing material is made from high-quality expanded PTFE material, offering excellent corrosion resistance and chemical stability. It can withstand the erosion of various corrosive substances, such as acids, bases, and solvents, thereby reducing the risk of leaks. Secondly, this material possesses excellent filling properties and creep resistance. It can adapt to various pressure and temperature changes, providing a reliable sealing effect. Once again, the installation of Fle*ngSeal expanded PTFE sealing tape is relatively simple and quick. Generally, it is sufficient to secure the strip to the sealed surface, without the need for complex cutting and adjustment, thereby saving installation time and labor costs. Furthermore, compared to traditional gaskets, the Fle*ngSeal material offers greater cost competitiveness in terms of strips. The material used for these strips is less abundant, resulting in lower costs. Additionally, the long-term reliability and durability of Fle*ngSeal strips help to reduce maintenance and replacement expenses.
