Steel-lined PTFE pipe is a kind of green plastic pipe with the most anti-corrosion, wear-resisting, energy saving and environmental protection. Its wide application has accelerated the process of new environmental protection roads in mines to a certain extent. It not only realizes the low-carbon and environmental protection of mine operation, but also saves cost and manpower and material resources for mining investment enterprises, makes mine transportation safer and more reliable, and increases transportation speed.
Now, a new type of plastic pipe that meets the needs of society and has been applied-steel lined PTFE pipe. Most industrial sewage requires extremely corrosion-resistant pipelines, because industrial sewage contains corrosive media, and these corrosive media must be toxic and harmful chemicals. To transport and process these toxic and hazardous chemicals, green anticorrosive steel-lined PTFE pipelines are the best choice.
The tetrafluoroethylene pipe fittings are made of ordinary carbon steel pipe as the matrix, and are lined with thermoplastic polytetrafluoroethylene (Teflon or PTFE, F4) plastic with excellent chemical stability, processed by a specific process. It not only has the mechanical properties of steel pipes, but also has the characteristics of high corrosion resistance of tetrafluoroplastics, anti-scaling, and not easy to grow microorganisms. It is an ideal pipeline for transporting strong acids, strong alkalis, industrial salts and strong corrosive gases.
High chemical stability:
It can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents. Very suitable for feeding high-purity chemicals. The wide temperature range is -30℃~-250℃. The low friction coefficient is generally only 0.04, which is a very excellent self-lubricating material, and the friction coefficient does not change with temperature changes. Excellent anti-adhesion: the inner wall of the tube is not easy to adhere to colloids and chemicals. Excellent aging resistance, can be used outdoors for a long time. Excellent electrical insulation performance, PTFE is a highly non-polar material with good dielectric properties, extremely high electrical resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials. High flexibility and resistance to bending. Part of the tube has high transparency, and the internal fluid condition can be easily observed.
1) High temperature resistance-working temperature up to 250℃
2) Low temperature resistance-has good mechanical toughness, even if the temperature drops to -196 ℃, it can maintain 5% elongation.
3) Corrosion resistance-It is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents.
4) Weather resistance-has the best aging life among plastics
5) High lubrication-is the smallest friction coefficient among solid materials.
6) No adhesion-it is the smallest surface tension among solid materials and does not adhere to any substance.
7) Non-toxicity|——non-toxicity to organisms
