Bilayer and Monolayer, High Temperature Resistant HDPE

Designed to resist higher temperatures, TKP-TR expands the application field of the PE pipe up to 180ºF. The TKP PE pipeline includes pipes and fittings.



  • PERT is Polyethylene pipe that can be subject to temperatures above 140°F to 180°F.

  • The heat fusion parameters defined for PE-4710 or PE-100 applies.

  • The same standard HDPE pipe burial design parameters apply.

  • The bend radius is 25 times the pipe OD.

  • The standard thermal rerating parameters until 140°F applies.

  • From 140°F to 180°F PERT re-rating are incorporated into the Pressure Table 1.

  • The chemical resistance for the HDPE applies in whole and in some cases offer a better resistance than the normal PE-4710 ( example: against chlorine).

  • TKP offers diameters from 3” to 48” and of course, TKP-FIT offers the fittings.


  • Pipe for the conduction of fluids during the leaching process in mining.

  • Tube for the cunduction of fluids during bioleaching (bacterial process) in copper mines.

  • Transport of hot water in geothermal wells.

  • Oils and Gass Gathered Applications.



This strength versus time graph shows the relation between the European definition of the work pressure, based in the MRS ( ISO) against the use the HDB in the American mode (ASTM) the European method is based in longer observation of the behavior against pressure, and uses a low safety factor for the definition of the work pressure. The definition of the work pressure is the same comparing the TKP-TR –PE100 pipe against PE4710 pert pipes, especially in the critical range above the 140°F when the real work for those pipes really starts.

Because of the European origin of the resin, the material is rated PE-100 and is included in the PPI's TR4 with an MRS=10 MPA according with ISO-9080.


According with the ISO-10508 standard, the design temperature profile is for:

  • 50 years @ 20°C (68°F)

  • 40 years @60°C (140°F)

  • 10 years @ 80°C , (180°F)

  • 1 year @ 90°C (194°F)

  • 100 hrs for 100 °C (212°F)


Higher standards in properties:

  • Chlorine resistance.

  • High quality water supply.

  • Chemical resistance.

  • Resistance to crack propagation.

When the application is related with the transport of hot water:


  • Chlorine resistance:

TKP-TR is qualied in the highest ranking for chlorine resistance (CLASS 5) ,resisting towards oxidizing conditions tested with the chlorine resistance test (ASTM F2769 & ASTM F2023)

  • High quality water supply:

TKP-TR preserves the water purity and quality ( taste and odor): Value of 2 of the pipe tested with standard EN1622 @ 140°F with a maximum of 4 in the industry standard.


When the application is related with the transport of industrial and chemical fluids:

  • Very good resistance against aggressive chemicals:

The high temperature resistance of TKP-TR , does not interfere with its chemical resistance, what means the pipe has the same resistance of the normal HDPE pipe.


For all the applications:

  • Resistance of crack propagation:

TKP-TR pipe has more resistance to the crack propagation that normal PE-4710 or PE-100 pipe.
