Introduction of polytetrafluoroethylene pipe is actually a high-quality plunger extrusion pipe, is a kind of use of special processing technology, and then let the steel pipe and the plastic pipe for the close union together. This product can withstand the positive pressure of 1.6Mpa, the corresponding negative pressure can withstand 77Kpa; can be used in the temperature range of -60 ℃ to +260 ℃, in addition to this product can have a very reliable corrosion resistance. So what are the specifications of PTFE pipe and PTFE pipe price? The following is a detailed introduction to the relevant information.
In the use of this product can be transported at high temperatures of some highly corrosive gas and liquid, other pipes can not be replaced. The PTFE pipe can be widely used in machinery and chemical aviation and electrical and electronic related fields.

Polytetrafluoroethylene (PTFE) pipe price
The price of the PTFE pipe is based on the specifications of the product to be priced for different brands are also a certain deviation. For example, some of the prices seen on the Internet, such as 13 * 15 specifications of PTFE pipe price is 12 yuan a meter; there are 26 * 20 specifications of PTFE pipe price is 47 yuan a meter.
Characteristics of PTFE tube
Polytetrafluoroethylene (PTFE) has excellent chemical stability, resistant to all strong acids, strong alkalis, strong oxidizing agents, and a variety of organic solvents do not interact. PTFE use a wide range of temperatures, atmospheric pressure can be used for a long time in -180 ℃ ~ 250 PTFE has a very low friction factor, is a good friction reduction, self-lubricating materials, its static friction coefficient is less than the coefficient of kinetic friction, so it is used to make bearings have the advantages of small starting resistance and smooth running. Because PTFE is non-polar, heat-resistant and non-absorbent, so it is an excellent electrical insulating material. Also has excellent aging resistance, non-stick and non-flammable.
Polytetrafluoroethylene made of rods, tubes, films, bearings, gaskets, valves and other profiles and parts, widely used in machinery, chemical industry, aviation, electrical and electronic, defense industry, cutting-edge science and technology, medical and health care, and electrical insulation and other fields.
What should be paid attention to when using steel lined PTFE pipe
1, handling and stacking PTFE pipe sections and fittings, should avoid strong vibration or collision
2, PTFE pipe should be checked before installation of the lining layer is intact and to keep the pipe clean
3, rubber, plastics, fiberglass, rubber, plastic, fiberglass, paint and other lining pipe components, should be stored in the temperature of 4-50 ℃ indoor, and should avoid sunlight and heat radiation.
4, steel lined PTFE pipe installation should be soft or semi-hard gaskets, when it is necessary to adjust the installation length error, it is appropriate to use the replacement of the same material gasket thickness. The thickness of the gasket should not exceed 20% of the design thickness
5, ? Anti-corrosion PTFE pipe installation, shall not be welded, heated, twisted or knocked.
After the above brief introduction, I believe that friends have a good understanding of PTFE pipe specifications and the corresponding PTFE pipe price. At present, the chemical stability of PTFE itself is very good, can adapt to all the strong acids and alkalis, but also has a good resistance to strong oxidizing agents, and a variety of organic solvents will not occur in a variety of roles. In addition, the corresponding use of PTFE temperature range is still relatively wide, especially at atmospheric pressure can be long-term -180 ℃ ~ 250 ℃. For 250 ℃ high temperature treatment after 1000h, the corresponding mechanical properties will rarely change. In addition, PTFE friction factor is also very low, can be said to be very good friction reduction, in addition to this material also has a self-lubricating material.
The above is about PTFE pipe, I hope it can help you!
