Advantages of steel-lined PTFE pipes in industrial sewage

Steel-lined PTFE pipe is a green plastic pipe that is anti-corrosion, wear-resistant, energy-saving and environmentally friendly. Most industrial sewage discharges require extremely corrosion-resistant pipes, because industrial sewage contains corrosive media, and these corrosive media cannot do without toxic and harmful chemicals. To transport these toxic and harmful chemicals, green anti-corrosion steel-lined PTFE pipelines are the best choice.

Steel-lined PTFE pipe fittings are made of ordinary carbon steel pipe as the matrix, lined with thermoplastic PTFE plastic with excellent chemical stability, and processed by a specific process. It not only has the mechanical properties of steel pipes, but also has the characteristics of high corrosion resistance, no scaling, and not easy to grow microorganisms of tetrafluoroplastics. It is an ideal pipeline for transporting strong acids, strong alkalis, industrial salts, and strong corrosive gases.

High chemical stability: resistant to strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, oleum, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents. Suitable for high-purity chemical feeding. Widely used temperature range is -30℃~-250℃. The low friction coefficient is generally only 0.04, which is an excellent self-lubricating material, and the friction coefficient does not change with temperature. Excellent anti-adhesive properties: colloids and chemicals are not easy to adhere to the inner wall of the tube. 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 resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulating materials. High flexibility and resistance to bending. Part of the tube has high transparency, and it is easy to observe the internal fluid condition.
