Teflon lined pipes are piping systems where the inner surface of the pipe is coated or lined with Teflon (polytetrafluoroethylene or PTFE) material, offering exceptional chemical resistance and non-stick properties, commonly used in industries such as chemical processing, pharmaceuticals, and food manufacturing. These pipes provide a durable and corrosion-resistant solution for transporting corrosive or high-purity fluids, ensuring efficient and safe fluid transfer operations.
