Which properties are you looking for?

Long-term stability

Withstands corrosive chemicals

Few materials have undergone such extensive long-term testing as one in the Uponor inPEX pipes. Ten years continuous pressure testing at 95°C
and an uninterrupted longterm test since 1972 are just two examples. The material has been well tried and tested in many different applications over a long period of time.

When the pipes are heated to its softening temperature, the material reverts to its original shape. This characteristic is used to give a very reliable method for shrink-mounting sealing devices, for example.

Chemicals that can cause cracks in ordinary plastic pipes do not affect Uponor inPEX pipes. The material is resistant to the majority of chemicals, even at high temperatures.

Flexible

The flexibility of Uponor inPEX pipe is yet another advantage compared with metal pipes. There is no need for expensive expansion bellows or their equivalents.

The pipes can be used at a working temperature of 95°C, but withstand 120°C within time and pressure limits.

Uponor inPEX is a material with low environmental impact during both manufacturing and energy recovery.

Low weight

Low friction

The pipes absorb sound, which means you can transport solid materials, e.g. wood-chips, without the risk of loud noise levels.

Uponor inPEX pipes weigh just a fraction of an equivalent metal pipe. This is often an advantage, and sometimes a crucial one.

The extremely low friction coefficient in Uponor inPEX pipes reduces the pressure-drop in the pipe-work and minimizes the risk of deposits.

Clean

Resistance to abrasion

Vibration absorbing

The pipe does not release any harmful substances. That’s why it’s also approved for transporting drinking water. The material’s exceptional cleanness is also utilized in medical equipment.

The abrasion characteristics are very good; erosion corrosion does not occur even at high water speeds. That’s why our pipes are used to transport highly abrasive sand slurry, for example.

The pipes absorb and withstand vibrations. There’s no need to combine metal pipes with vibration-absorbing hoses or connectors, giving you higher reliability and lower costs, particularly during installation.

Electrically insulating

Withstands extreme cold

The electrical insulating characteristics of the pipe are on a par with the best insulating materials. The material is non-polar and also totally free from impurities.

The pipe material has unchanged impact strength even at temperatures below -100°C. This characteristic is exploited in refrigeration systems for ice rinks, for example.

The pipe withstands scratches without being weakened because it is resistant to crack growth. This characteristic makes it possible, for example, to locate pipes directly in stony ground without expensive ground-works.

The great freedom to shape Uponor inPEX pipes makes them an excellent replacement for e.g. shaped metal pipes.
