HIGH TEMPERATURE GEO PIPE

FOR USE WITH WASTE HEAT AND THERMAL STORAGE APPLICATIONS

 PE-RT Type II is a high-performance PE for hot and cold water pipe. It was developed by using a new catalyst technology as well as new concept which lead to a BOCD (Broad Orthogonal Co-Monomer Distribution) molecular structure. Pipes made out of SP 988 offer excellent properties to both processability and long term hydrostatic strength.

Stronger, greener, fusible and more flexible, PE-RT strikingly outperforms PEX and HDPE.  Why? PE-RT is a more pure material, manufactured from polyethylene – raised temperature,  PE-RT does not need to be cross-linked, eliminating the need for additives, resulting in a more pure product.  It is this key difference that makes PE-RT stronger and more flexible than PEX, while also being recyclable and fusible.

POLYETHYLENE RAISED TEMPERATURE (PE-RT) PIPE

PE-RT tubing comes in nominal sizes ranging from 1/4 to 6 in. copper tube size (CTS). PE-RT tubing with SDR-9 and SDR-11. Consult the specific PE-RT manufacturer's literature and listings for appropriate pressure ratings. PE-RT tubing and pipe are sold in coils and straight lengths.

 

Definition: PE-RT is a polyethylene (PE) resin in which the molecular architecture has been designed such that a sufficient number of tie chains are incorporated to allow operation at elevated or raised temperatures (RT). Tie chains "tie" together the crystalline structures in the polymer, resulting in improved properties such as elevated temperature strength and performance, chemical resistance and resistance to slow crack growth.

 

Overview: PE-RT is a high-temperature flexible plastic pressure pipe with a 35-year history of successful use in the European market with extensive testing for durability and material performance. It was first introduced in North America in 2003 and is used in aluminum composite (multilayer) barrier tubing and solid wall tubing and pipe. Applications include plumbing, water service, hydronic heating and cooling, snow and ice melting and ground source geothermal piping systems. PE-RT is approved in all model plumbing and mechanical codes across the United States. .

 

PE-RT: Advantages

  • Safety of potable water and long-term reliability

  • Resistance to corrosion, tuberculation, deposits

  • Chlorine and chloramine resistance

  • Flexibility to speed installations

  • Freeze-break resistance

  • Lightweight, easy to transport

  • Noise and water hammer resistance

  • Low scrap value, avoiding jobsite theft

  • Durability and toughness to survive jobsite installations

  • No flame used for joining, with many fitting and joining options

  • Recyclable, eco-friendly material

  • Heat Fusible for virtually leak-free performance

 

PE-RT Applications

  • Hot- and cold-water plumbing distribution, residential and commercial

  • Radiant heating and cooling systems (floors, walls, ceilings)

  • Hydronic piping and distribution (radiators, fan coils, etc.)

  • Chilled water piping

  • Outdoor snow and ice melting

  • Turf conditioning/pitch heating

  • District Heating/Cooling

  • Water Service Lines (CTS and IPS)

  • Geothermal ground loops (vertical boreholes, horizontal layouts)
