Description of the PTFE Tube
The PTFE tube is manufactured using a piston extrusion process. A specific processing technique mechanically joins the steel and plastic tubes. Testing shows the tube tolerates an overpressure of 1.6 MPa and an underpressure of 77 kPa. It is suitable for use between 60°C and +260°C. Its corrosion resistance has been quantified according to industry protocols, thereby allowing the tube to transport highly corrosive gases and liquids at elevated temperatures where alternative tubes are not applicable.
