PTFE rubber joint is a special rubber joint, which is made of PTFE and organic peroxide cross-linking, with excellent corrosion resistance, high temperature resistance, aging resistance and oil resistance. Due to its excellent performance, PTFE rubber joints are widely used in chemical, petroleum, pharmaceutical, light industry and other fields, and become an important part of the pipeline system.
First, the characteristics of PTFE rubber joints.
1.Strong corrosion resistance: PTFE has excellent corrosion resistance, which can resist the erosion of corrosive media such as strong acids, strong alkalis, and salts, thus ensuring the long-term stable operation of the pipeline system.
2.Good high temperature resistance: PTFE has a very high melting point and is able to maintain good properties at high temperatures. PTFE fittings can be used for a long time in the temperature range of -200 +260, which meets the needs of various high-temperature pipes.
3.Good aging resistance: PTFE is not easy to oxidize in the air and is not easily affected by ultraviolet rays, so PTFE rubber joints have a long service life.
4.Good oil resistance: PTFE has very good permeability resistance to various oil media, which can effectively prevent the erosion of oil media and ensure the sealing performance of the pipeline system.
5.Easy installation: PTFE rubber joints are flange connected, easy to install, and can withstand large pressure and vibration, ensuring the safe and stable operation of the pipeline system.
Second, the application of PTFE rubber joints in pipeline systems.
PTFE rubber joints are widely used in various pipeline systems, such as chemical pipelines, petroleum pipelines, pharmaceutical pipelines, light industrial pipelines, etc. In these fields, the role of PTFE rubber joints is mainly to connect pipelines, compensate for pipeline thermal expansion and contraction, absorb pipeline vibration, and prevent pipeline system leakage. At the same time, PTFE rubber joints can also prevent the pipeline system from being disturbed by external factors, such as wind shock, etc., and improve the safety and stability of the pipeline system.
3. Precautions for the use of PTFE rubber joints.
1.When installing PTFE rubber joints, it should be ensured that the flange end face is flat, the center deviation of the bolt hole does not exceed 5 of the hole diameter, and the free penetration of the flange bolt should be ensured.
2.When handling and storing PTFE rubber joints, they should be protected from severe impact and crushing to prevent damage to the internal structure of the joints.
3.When using PTFE rubber fittings, avoid exceeding the design pressure and temperature range to prevent damage to the joints.
4.When replacing PTFE rubber joints, the old gaskets and residues should be removed first, and then an appropriate amount of sealant should be applied to ensure the sealing performance of the joints.
IV. Conclusions. As a special rubber joint, PTFE rubber joint has excellent corrosion resistance, high temperature resistance, aging resistance and oil resistance, and is widely used in various pipeline systems. When using PTFE rubber joints, they should be operated and maintained in accordance with relevant regulations and precautions to ensure their long-term stable service life and good sealing performance. With the continuous progress of science and technology and the continuous expansion of application fields, PTFE rubber joints will play a more important role in the pipeline system in the future.
