Rehau Insulpex Flexible energy transfer pipe for underground installations

Insulpex is specially designed for the efficient transfer of hot or cold water through buried insulated pipelines. INSULPEX consists of PEXa O2 Barrier pipe surrounded by a solid layer of CFC-free polyurethane foam insulation and an LDPE outer jacket.

INSULPEX is available in one- and two-pipe configurations. The two-pipe configuration combines return and supply pipes, for even faster installations.

Sold in 100 ft coils, Free shipping.



The most critical points in a pre-insulated PEXa piping system design are:

– To ensure the flow requirement and pressure loss are within the circulator's performance capability.

– To design the buried depth to use energy efficiently and to avoid heaving of the pipe in the coldest months.

– To transition to building service piping immediately upon enter- ing the building and to properly secure the transition fitting.



In view of the increasing need to minimize CO2 emissions as much as possible, local heating supply technology is becom- ing increasingly important. Pioneering technologies, combining optimal functionality with low energy losses, are the basis for REHAU INSULPEX pre-insulated PEXa piping systems.

3.1 System Advantages

INSULPEX is flexible, pre-insulated PEXa piping with closed-cell polyurethane (PU) foam bonded insulation.
– Flexible pipe system ensures cost-effective heat distribution
– Minimal linear expansion, as pipe layers are fully bonded

– No need for expansion bellows or compensators
– Fully bonded pipe layers limit water penetration to absolute

– System components for a variety of applications

3.2 Applications

INSULPEX is used predominantly below ground and is ideal for applications including:
− District heating
− Energy transfer

− Snow and ice melting − Chilled water
− Process piping
− Hydronic piping

− Geothermal

− Industrial and agricultural − Outdoor wood furnace

Insulpex pipe consists of O
2 Barrier PEXa pipe encased in closed-cell polyurethane (PUR) foam insulation, with a protective low-density polyethylene (PE) outer casing. O2 Barrier pipe is made of high-quality crosslinked polyethylene, manufactured using the high-pressure peroxide method (PEXa). O2 Barrier pipe has a co-extruded oxygen diffusion layer that complies with the requirements of DIN 4726. O2 Barrier pipe is manufactured by REHAU in a plant using a quality management system that is certified to ISO 9001.

Insulpex pipe meets the requirements of DIN 16892 and 16893. The size listed in the description is the nominal diameter in millimeters, according to DIN 16893. Metric pipes are SDR11 and are compatible with SDR11 compression-sleeve fittings. Refer to Insulpex Technical Manual (Art. 855.630) for pipe dimension details, capacities and temperature/pressure ratings.
