The Thermalok® Process Advantages

  • Ensures that the steel Pipe and liner will act as one integral piece
  • Ensures a snug liner fit – a procedure adhered and maintained to eliminate undesirable stress in the finished product
  • The process allows the lined pipe to maintain dimensional stability and perform under vacuum, pressure and thermal cyclic conditions
  • Prevents liner from buckling and/or the flares from getting cut off or sucked in

Process Technology & Engineering Expertise

Proven methods with engineering techniques for producing optimized lined pipe work, best suited for reducing permeation

  • Fine powders of approved grades are first conditioned to the desired temperature
  • Tubes are extruded to a size somewhat larger than the I.D. of steel housing. Extrusion dies are designed to ensure a higher wall thickness than that specified in the ASTM
  • Extruded tubes are sintered using a programmed sinter cycle. In this process, the heating and cooling cycle is precisely controlled and monitored to ensure that the entire tube achieves a high molecular crystallinity with low void content which helps in reducing permeation and allows the pipe work to work for an extended time period
  • Sintered PTFE tubes are first “roll tested” and then subjected to a series of quality checks which are carried out in our laboratary to ensure liner integrity and compliance to ASTM specifications
  • The liner is then drawn through sizing dies at controlled draw rates which results in a calculated reduction in the liner diameter. This drawn liner is inserted into the metal pipe
  • In the relaxation process which follows, the liner is allowed to relax inside the pipe housing, resulting in a snug liner fit, a procedure adhered and maintained to eliminate undesirable stress in the finished product
  • The two ends of projected liners are then hot flared so as to form a gasket over the flange face using controlled temperature, time and pressure
  • Finished pipes are then tested as per the testing requirements specified in the ASTM F 1545
  • This unique method of lining pipes is known as the Thermalok® process which was then patented by Resistoflex. This process ensures that the steel pipe and liner act as one integral piece
  • The final product – an “optimized lined piping system” – the full strength of the metallic pipe and the corrosion resistance of the liner
  • The Thermalok® process provides dimensional stability to the lined pipe under vacuum, pressure, and thermal cyclic conditions, and also prevents the liner from buckling and/or the flares to get cut off.
