  When it comes to the use of PTFE tubes, they can be used in the world, there are aerospace in the sky, and the underground is countless. Because of the excellent characteristics of PTFE tubes, the current uses are very wide. For example, recently A well-known environmental protection project to reduce flue gas pollution, including a heat exchanger, which can increase the temperature of the flue gas at the chimney outlet, thereby reducing the amount of flue gas. The heat exchanger will use a large number of PTFE tubes. .

  PTFE tube, scientific name PTFE tube (referred to as F4 tube, PTFE tube) is the use of high-quality plunger extruded tube, using special processing technology to make the steel tube and plastic tube tightly combined, can withstand positive pressure 1.6 Mpa, negative pressure: 77Kpa; it can be used normally within -60℃~+260℃, with reliable and excellent corrosion resistance. Transporting highly corrosive gases and liquids at high temperatures cannot be replaced by other pipelines. PTFE tubes are now widely used in machinery, chemicals, aviation, electrical and electronics, defense industry, cutting-edge technology, medical and health, and electrical insulation.

  PTFE tube features: PTFE tube has excellent chemical stability, can withstand all strong acids, strong alkalis, strong oxidants, and does not interact with various organic solvents. PTFE has a wide operating temperature range. It can be used for a long time at -180℃~250℃ under normal pressure. After 1000h of treatment at 250℃, its mechanical properties will change little. PTFE has a very low friction factor, is a good anti-friction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running when used to make bearings. Because PTFE is non-polar, heat-resistant and does not absorb water, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility.

  Common features of PTFE tube:

  Operating temperature: -200 degrees to 260 degrees

  Ease of processing: can flanging

  Aging resistance: can be exposed to ozone and sunlight for a long time without aging

  High transparency: the refractive index is low among all plastics, and the flow of the medium in the pig can be viewed directly

  Corrosion resistance: able to withstand the action of all strong acids, strong oxidants, strong reducing agents and various organic solvents except for molten alkali metals, fluorinated media and those above 300°
