  1. Teflon flanged tube

  Flanging pipes include straight pipes and corrugated pipes. For reasons of usage, some customers specify flanging during the production process. The following Teflon flanging pipes are customized Teflon flanging pipes required by customers.

  Teflon performance:

  1. Non-sticky: Teflon is inert, almost all materials are not bonded with Teflon, and the thin film also shows non-stick performance.

  2. Heat and cold resistance: Teflon has excellent heat and low temperature resistance. In a short time, it can withstand temperature to 300℃, melting point is 327℃, and it will not melt at 380℃. Generally, it can be used continuously between 240℃ and 260℃. It has remarkable thermal stability. It can work at freezing temperature. No embrittlement, cold resistance to 190℃.

  3. Lubricity: Teflon has a low coefficient of friction. The friction coefficient changes when the load is sliding, but the value is only between 0.04-0.15.

  4. Non-hygroscopicity: The surface of Teflon does not stick to water and oil, and it is not easy to stick to the solution during production operations. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

  5. Corrosion resistance: Teflon is hardly corroded by chemicals, and can withstand all strong acids (including aqua regia), strong alkalis, and strong acids except molten alkali metals, fluorinated media, and sodium hydroxide above 300°C. The role of oxidants, reducing agents and various organic solvents can protect parts from any kind of chemical corrosion.

  6. Weather resistance: non-aging, the best non-aging life among plastics.

  7. Non-toxic: In normal environment within 300℃, it is physiologically inert, non-toxic and can be used as medical and food equipment.

  8. Insulation: Very good dielectric constant and high insulation.

  The role of Teflon:

  The full English name of Teflon is Polytetrafluoroetylene, Teflon, PTFE, F4, etc. for short. Teflon (Polytetrafluoroethene) is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon has the characteristics of high temperature resistance, its friction coefficient is very low, so it can be used for lubrication, and it has become an ideal coating for easy-to-clean woks and water pipes. It can be used for pipeline anti-corrosion, high and low temperature resistance, and corrosion resistance. Used in harsh environments such as lubrication, engineering, electronics, electrical appliances, and aviation.

  2. Explosion-proof Teflon tube

  Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), is generally called "non-stick coating" or "easy to clean material". The vernacular name Teflon tube, Teflon tube, PTFE tube. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used for lubrication and become an ideal coating for easy cleaning of the inner layer of water pipes.

  Polytetrafluoroethylene is known as "the king of plastics." Roy Plankert, the father of fluororesin, began to study freon substitutes at DuPont in the United States in 1936. They collected part of tetrafluoroethylene and stored it in steel cylinders to prepare for the second Tian proceeded to the next experiment, but when the cylinder pressure relief valve was opened the next day, no gas escaped. They thought it was a gas leak, but when the cylinder was weighed, they found that the cylinder did not lose weight. They saw open the cylinder and found a large amount of white powder, which was polytetrafluoroethylene.

  They found that polytetrafluoroethylene has excellent properties and can be used for anti-fusion sealing gaskets for atomic bombs and artillery shells. Therefore, the US military kept this technology secret during World War II. It was not decrypted until the end of World War II, and the industrial production of polytetrafluoroethylene was realized in 1946.

  The explosion-proof Teflon tube is resistant to all other chemicals, and does not change when it is boiled in aqua regia. It is widely used in various occasions that require resistance to acids, alkalis and organic solvents. It has airtightness, high lubrication, non-stick, electrical insulation, good anti-aging ability, and excellent temperature resistance (it can work for a long time at a temperature of plus 250°C to minus 180°C). Teflon itself is not toxic to humans. The operating temperature is -190~250℃, allowing rapid cooling and heating, or alternate operation of cooling and heating. Pressure -0.1~6.4Mpa.

  The production of explosion-proof Teflon tubes has solved many problems in the chemical, petroleum, pharmaceutical and other fields. Polytetrafluoroethylene seals, gaskets, gaskets. Polytetrafluoroethylene seals, gaskets, and gaskets are made of suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, PTFE has the characteristics of chemical resistance, and it has been widely used as a sealing material and filling material. The dispersion can be used as an insulating dipping solution for various materials and as an anticorrosive coating on the surface of metal, glass, and ceramics. Various PTFE rings, PTFE gaskets, PTFE packings, etc. are widely used for sealing various anticorrosive pipeline flanges. In addition, it can also be used for spinning, polytetrafluoroethylene fiber-fluorine fiber (foreign trade name is Teflon).
