Long-term stability
  

Few materials have undergone such extensive long-term testing as Wirsbo-inPEX. Ten years continuous pressure testing at 95°C and an uninterrupted long-term 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.

Thermal memory
  

When Wirsbo-inPEX is 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.

Withstands corrosive chemicals

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

Flexible
  

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

Withstands high temperature

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

Low environmental load
   

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

Sound-absorbing   

Wirsbo-inPEX absorbs sound, which means you can transport solid materials, e.g. wood-chips, without the risk of loud noise levels.

Low weight

Wirsbo-inPEX weighs just a fraction of an equivalent metal pipe. This is often an advantage, and sometimes a crucial one.

Low friction

The extremely low friction coefficient of Wirsbo-inPEX reduces the pressure-drop in the pipework and minimizes the risk of deposits.

Clean
   

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.

Resistance to 
abrasion   

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

Vibration-absorbing
   

Wirsbo-inPEX absorbs and withstands 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
   

The electrical insulating characteristics of Wirsbo-inPEX are on a par with the best insulating materials. The material is nonpolar and also totally free from impurities.

Withstands extreme 
cold   

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

Scratch-resistant

Wirsbo-inPEX 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 groundworks.

Ductile  

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