Reinforced PEX

Reinforced PEX is a flexible pipe perfectly suited for secondary networks with high requirements to pressure and temperature. Kevlar reinforcement allows the pipes to be used at maximum operating pressures of up to 10 bar.
Reinforced PEX pipes are made of continually extruded PEX-a. After extrusion, the pipes are reinforced with a single-layer Kevlar wire, which is wound around the perpendicular, longitudinal axis.

The Kevlar wire is a synthetic wire of poly-phenylentere-phthalamid. The wire has a tensile strength of 3,620 MPa, which is several times stronger than steel. The single layers in the pipe system are bonded together by means of highly adhesive glue. The inside pipe diameter corresponds to the inside diameter of an ordinary SDR11-6 bar PEX pipe.

The Kevlar reinforcement increases the maximum internal pressure in the pipes from 6 to 10 bar at a temperature of 95°C.

 

Advantages of reinforced PEX:

  • Increased flexibility and reduced weight, thus a considerable advantage during transportation and installation
  • Increased maximum permissible pressure in the pipe
  • Increased maximum permissible temperature in the pipe
  • The number of joints is minimised as compared to steel pipe systems
  • Does not require trained welders
  • System with long service life
