PTFE pipe is the use of high-quality plunger extrusion pipe, the use of special processing technology, so that the steel pipe and plastic pipe closely combined, can withstand positive pressure 1.6Mpa, negative pressure: 77Kpa; can be in -60 ℃ ~ 260 ℃ within the normal use, with reliable and excellent corrosion resistance. Transporting strong corrosive gases and liquids at high temperatures, which cannot be replaced by other pipelines.

PTFE pipe is used for wire insulation sheath, corrosive fluid medium pipeline, various high frequency use of electrical insulation parts, etc.
Polytetrafluoroethylene (PTFE) has excellent chemical stability, can withstand all strong acids, strong bases, strong oxidants, and does not work with various organic solvents. PTFE has a wide range of temperature, and can be applied to -180 ℃ ~ 250 ℃ for a long time under normal pressure. After being treated at 250 ℃ for 1000h, its mechanical properties change very little. PTFE has a very low friction coefficient, is a good antifriction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so used to make the bearing has the advantages of small starting resistance, smooth operation. Because PTFE is non-polar, heat-resistant and non-absorbent, it is also an excellent electrical insulating material. Also has excellent aging resistance, non-sticky and non-flammable.
PTFE made of bars, pipes, films, bearings, gaskets, valves and other profiles and parts, widely used in machinery, chemical, aviation, electrical and electronics, national defense industry, cutting-edge technology, medical and health and electrical insulation and other fields.
Although it is only a simple pipe, don't buy it blindly, especially PTFE pipe, because there are many unfavorable factors, so you must have a good understanding of the quality and grade of PTFE pipe before you decide to buy it to ensure the purchase of high-quality products.
First of all, you can touch the PTFE tube by hand. A good PTFE tube feels uniform and smooth, indicating that its manufacturing process is careful and comprehensive. However, the rough PTFE tube obviously cannot meet the requirements, and its manufacturing process is bound to have no intention.
Secondly, the general PTFE tube will have a specific color, so after observation if it is found that the color is abnormal, we must be cautious to buy. The color problem of the PTFE tube often reflects whether it adds a class of unqualified chemical components.
At the same time, the quality of PTFE pipes can be distinguished by smelling the smell. High-quality steel-lined PTFE pipes, especially those of environmental protection type, generally have no peculiar smell or little smell, but most pipes nowadays rarely reach the stage of completely free of peculiar smell.
In addition, the elastic test is also a way to prove the quality of the PTFE tube. If conditions permit, the elastic test of the PTFE tube can be carried out. Relying on this link, the quality of the tube can be known.
