1. teflon flanging tube
Flanging tubes have straight tubes and corrugated tubes. Some customers specify flanging during the production process because of their use. The following Teflon flanging tube is a custom-made Teflon flanging tube required by customers.

the performance of teflon:
1. Non-stick: Teflon is inert, almost all substances are not bonded to Teflon, and very thin films also show non-adhesive properties.
2. Cold and heat resistance: Teflon has excellent heat resistance and low temperature resistance. Short time temperature resistance to 300 ℃, melting point of 327 ℃,380 ℃ does not melt, the general work can be used continuously between 240 ℃ ~ 260 ℃, with significant thermal stability, it can work at freezing temperature without embrittlement, cold resistance to 190 ℃.
3, lubricity: Teflon has a lower coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.04 and 0.15.
4. Non-hygroscopicity: Teflon surface is not stained with water and oil, and it is not easy to be stained with solution during production operation. If there is a small amount of dirt, it can be removed by simple wiping. Short downtime saves man-hours and improves productivity.
5, corrosion resistance: Teflon is almost not subject to chemical erosion, can withstand in addition to molten alkali metal, fluoride medium and above 300 ℃ sodium hydroxide outside all strong acid (including aqua regia), strong alkali, strong oxidant, reducing agent and a variety of organic solvents, can protect parts from any kind of chemical corrosion.
6. Weather resistance: no aging, the best non-aging life in plastics.
7, non-toxic: 300 ℃ within the normal environment, with physiological inertia, non-toxic can be used for medicine and food equipment.
8, insulation: very good dielectric constant, high insulation.
the role of teflon:
Teflon is called Polytetrafluoroetylene in English, referred to as Teflon, PTFE, F4, etc. Teflon (Polytetrafluoroethene) is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used as lubrication, and it has also become an ideal coating for the inner layer of easy-to-clean wok and water pipes. Can be used for pipeline anti-corrosion, high and low temperature resistance, corrosion resistance. Lubrication and other engineering, electronics, electrical appliances, aviation and other harsh environments.
2. explosion-proof teflon pipe
Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE) is generally referred to as "non-stick coating" or "easy-to-clean material". The vernacular name Teflon tube, Teflon tube, Teflon tube. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become an ideal coating for easy cleaning of the inner layer of the water pipe.
Polytetrafluoroethylene is called "plastic king". Roy Planct, the father of fluororesin, began to study freon substitutes in DuPont Company in the United States in 1936. They collected some tetrafluoroethylene and stored it in steel cylinders for the next experiment. However, when the pressure reducing valve of the steel cylinder was opened the next day, no gas overflowed. They thought it was air leakage, but when the steel cylinder was weighed, they found that the steel cylinder did not lose weight. They sawed through the cylinder and found a large amount of white powder, which was Teflon.
They found that PTFE has excellent properties and can be used for anti-melting sealing gaskets for atomic bombs and artillery shells, so the US military kept the technology secret during World War II. It was not until the end of World War II that it was declassified and industrialized production of PTFE was achieved in 1946.
Explosion-proof Teflon tube can withstand all other chemicals, boiling in aqua regia also does not change, widely used in a variety of occasions need to resist acid and alkali and organic solvents. Sealing, high lubrication non-stick, electrical insulation and good anti-aging ability, excellent temperature resistance (can be in the positive 250 ℃ to negative 180 ℃ temperature for a long time). Teflon itself is not toxic to humans. The use temperature is -190~250 ℃, allowing quenching and quenching, or alternating hot and cold operation. Pressure -0.1~6.4Mpa.

The production of explosion-proof teflon tube has solved many problems in chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets. PTFE seals, gaskets, sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance, it has been widely used as a sealing material and filling material. The dispersion can be used as an insulating immersion liquid for various materials and as an anti-corrosion coating on the surface of metal, glass and pottery. All kinds of PTFE ring, PTFE gasket, PTFE packing, etc. are widely used in all kinds of anti-corrosion pipeline flange sealing. In addition, it can also be used for spinning, PTFE fiber-Fluoron (foreign trade name is Teflon).
