It is what it does for you!


Your Raised Temperature Piping Solution!

  1. Environmentally Resilient: POLY-PERT™ pipes are built to thrive in diverse environmental conditions, offering unmatched resistance to chemicals, UV radiation, and abrasion.
  2. Temperature Versatility: From extreme cold to high heat, POLY-PERT™ excels in handling a wide range of fluid temperatures. Its exceptional thermal stability guarantees consistent performance, even in the most demanding temperature fluctuations.
  3. High-Pressure Performance: Engineered to withstand rigorous operating pressures, POLY-PERT™ pipes deliver unwavering performance under challenging conditions. With fusible joints, superior strength, flexibility and durability, you can trust POLY-PERT™ to eliminate the risk of leaks and bursts.
  4. Lifespan Flexibility: POLY-PERT™ offers customers the unique option to increase the system's temperature if the lifespan is less than the design life of 114 years at 73°F. This adaptability ensures longevity tailored to your specific needs, for example capable of handling temperatures up to 230°F, for 1 year only. Lower temperatures provide longer service life.
  5. Water Hammer Resistant: POLY-PERT™ pipes are designed to combat water hammer effects, absorbing energy from sudden changes in fluid flow velocity. Their flexibility and toughness mitigate the risk of pipe damage, ensuring uninterrupted system reliability.

What is the
Pipe System?

ISO PERT TYPE II Class V pipe is the next evolution of Polyethylene Pipe System products. It is extruded and molded from Total Chemical’s XRT-70 resin for higher performance is used for the following conditions:

  • Raised Temperature up to 180°F, flowing hot-waters up to 180-psi pressure through POLY-PERT™ of various DR’s.
  • Highly aggressive chemicals, hydrocarbons, highly oxidative environments, hot waters, hot brackish waters, cold waters.
  • PERT under ISO Standards allows the engineer to select the appropriate DR (wall thickness) on the following factors.
    1. The temperature of fluid
    2. The operating pressure
    3. The minimum timeline
    4. Flow-stream chemical composition

What makes POLY-PERT™ so special is that you can use it at temperatures above 140°F up to 180°F, in standard DRs, matched to the pressure requirements of the pipeline.

Enhanced Pressure Capacity

Understanding the Tighter ISO Performance Envelope of POLY-PERT Pipes

In simpler terms, when we talk about a tighter "ISO" performance envelope, it means we're using a stricter conservative design coefficient "C" to assign the Maximum Operating Pressure (MOP). The end result is POLY-PERT™ pipe having a slightly higher capacity to handle pressure compared to the "ASTM" standards. POLY-PERT™ material has been extensively tested and fulfills all the requirements of a PERT Type II class 5 material according to the ISO 24033 standard.
