FVF PTFE Lined Pipe By Ram Extrusion

  • FVF PTFE lined pipes with shortest lengths are around 100mm depending upon nominal bore and the longest lengths is 6 meters for up to DN150 and 3 meters above this. Generally constructed from carbon steel pipe, and stainless steel is also popular for dangerous access area where there is the potential for external corrosion.
  • Its working temperature is high at the range of -29°C-180°C; except the molten alkali metals, element fluorine and aromatic hydrocarbon, lined products can be used in any chemical medium.
  • Vacuum resistance. In the range of -29°C-150°C, it is applicable for vacuum condition. In chemical production, the vacuum condition occurs due to cooling, longitudinal emissions, or medium backflow. 
  • It is high-pressure resistant . Within temperature working condition, it can sustain the working pressure of 3.0MPa.
  • It is penetration Resistant.It has excellent antiosmosis by adapting the high-quality PTFE and making it of high density and enough thickness after advanced lining processing.
  • PTFE advanced lining molding process achieved the status of syn chronous hot expansion or cold shrinkage for steel components and fluorine plastic.
