The lined PTFE pipes are based on steel pipes, with a layer of plastic film coated inside the steel pipe. The film on the PTFE-PP lined pipe can be applied either as liquid plastic coating or as solid plastic coating, thus combining the high strength and rigidity of steel pipes with the chemical resistance of plastics.

PTFE-lined PP, PO pipe medium operating temperature: -25°C to 260°C

Fluorinated PP, PO pipe medium working pressure: equal strength positive pressure 0.6MPa to 25MPa, negative pressure of 94Kpa at room temperature.
