In use, this product can transport some highly corrosive gases and liquids at high temperature, which is irreplaceable by other pipelines. This kind of PTFE tube can be widely used in machinery, chemical industry, aviation, electrical electronics and other related fields.

The price of PTFE pipe
The price of PTFE pipe is based on the specifications of the product, and different brands have certain deviations. For example, some prices seen online, such as 13* 15 PTFE pipe, 12 yuan meter; There are 26*20 specifications of PTFE tubes, the price of one meter in 47 yuan.
Characteristics of PTFE pipe
PTFE has excellent chemical stability, can resist all strong acids, alkalis and strong oxidants, and does not react with various organic solvents. Polytetrafluoroethylene has a wide temperature range and can be used for a long time at-180℃~250℃ under normal pressure. After treatment at 250℃ 1000 hours, its mechanical properties have little change. PTFE is a good antifriction and self-lubricating material with low friction coefficient, and the static friction coefficient is smaller than the dynamic friction coefficient. When used to make bearings, it has the advantages of low starting resistance and smooth operation. PTFE is nonpolar, heat-resistant and non-absorbent, and it is an excellent electrical insulating material. It also has excellent aging resistance, non-stick and incombustibility.
Polytetrafluoroethylene bars, pipes, films, bearings, washers, valves and other special-shaped materials and parts are widely used in machinery, chemical industry, aviation, electronics and electricity, national defense industry, cutting-edge technology, medical care and electrical insulation and other fields.
What should be paid attention to when using steel-lined PTFE pipe
1. When handling and stacking tetrafluoroethylene pipe sections and fittings, avoid strong vibration or collision.
2. Before the installation of tetrafluoroethylene pipeline, check the integrity of the lining layer and keep the pipeline clean.
3, rubber, plastic, glass fiber reinforced plastic, paint and other liner components, should be stored indoors at a temperature of 4-50℃, and should avoid the radiation of sunlight and heat sources.
4. Soft or semi-hard gaskets should be used for the installation of steel-lined tetrafluoroethylene pipes. When it is necessary to adjust the installation length error, the same material should be used to replace the gasket thickness. The thickness of the gasket shall not exceed 20% of the design thickness.
5、? Do not weld, heat, twist or knock when installing anticorrosion tetrafluoroethylene pipeline.
After the above brief introduction, I believe that friends have a good understanding of the specifications of PTFE pipes and the corresponding price of PTFE pipes. At present, PTFE itself has good chemical stability, can adapt to all strong acids and alkalis, and has good resistance to strong oxidants, and will not have various effects with various organic solvents. In addition, PTFE has a wide temperature range, especially at-180℃~250℃ for a long time under normal pressure. After treatment at 250℃ for 1000h, the corresponding mechanical properties changed little. In addition, the friction coefficient of PTFE is also very low, so it can be said that the friction reduction is very good. In addition, this material also has a self-lubricating material.
The above is the related content of PTFE tube, I hope it will help everyone!
