PTFE-lined pipes are composite pipes with ordinary steel pipes as the base material and polytetrafluoroethylene (PTFE) material lining the inner wall. They have extremely strong resistance to chemical corrosion such as acids, alkalis, and organic solvents, while also possessing low friction, non-adhesion, and high temperature resistance (typically -200℃ to 260℃). They are widely used in chemical, pharmaceutical, metallurgical, and environmental protection fields for transporting corrosive media,

PTFE (polytetrafluoroethylene, commonly known as "Teflon") lined pipes offer significant advantages in industrial transportation due to their unique material properties. The core benefits can be summarized in the following six points, balancing practicality and adaptability to various scenarios: * **Extreme Corrosion Resistance:** Resistant to strong acids (such as sulfuric acid and nitric acid), strong alkalis (such as sodium hydroxide), organic solvents (such as acetone and toluene), and stron
