Overcome the problem of corrosion! Super corrosion-resistant PTFE FEP is launched, empowering the chemical industry for safe production
When transporting highly corrosive media in the chemical industry, pipeline corrosion and leakage have always been the "hardest hit areas" of safety hazards. Recently, a certain industrial pipe company launched a highly corrosion-resistant PTFE FEP product for the chemical industry. The product is designed with a special multi-layer composite structure to achieve "all-round resistance" to strong acids, strong bases, and organic solvents, reducing equipment maintenance costs and ensuring production safety for chemical enterprises.
Although traditional teflon hose has certain corrosion resistance, there are still problems such as infiltration and aging when transporting extreme media such as concentrated nitric acid, hydrofluoric acid, and high-temperature strong alkali. Frequent pipeline replacement is required, which not only increases production costs but also easily leads to leakage accidents. The R&D team of a certain industrial pipe company analyzed the chemical characteristics of different corrosive media and adopted a three-layer composite structure consisting of "inner layer pure iron fluorine dragon+middle layer glass fiber reinforcement+outer layer corrosion-resistant coating". The inner layer pure iron fluorine dragon ensures that the medium does not come into contact with the pipeline, the middle layer reinforcement structure enhances the compressive strength of the pipeline, and the outer layer coating further isolates the external corrosive environment. After testing, the product was soaked in concentrated nitric acid at 80 ℃ for 30 days, with a weight loss rate of only 0.2%. It was continuously used in a 50% sodium hydroxide solution for 12 months without any leakage or deformation, and its corrosion resistance reached the international leading level.
In the renovation of the nitric acid delivery system in a large fertilizer plant, the use of ultra strong corrosion-resistant PTFE corrugated hose has extended the pipeline replacement cycle from the original 6 months to 3 years, saving the enterprise over 2 million yuan in maintenance costs annually. ”The market manager of a certain industrial pipe company introduced that this product has been widely used in chemical, pharmaceutical, electroplating and other fields, serving more than 100 customers. Industry experts point out that the promotion of super corrosion-resistant Teflon Bellows will promote the transformation of pipeline systems in the chemical industry from "passive maintenance" to "active protection", significantly reducing the incidence of safety accidents and providing guarantees for the high-quality development of the chemical industry.
