Pexal Pipe

The Pexal pipe system has been developed to speed installation and increase functionality: with just one type of pipe and one type of fitting, you can install your gas system.

The Pexal multi-layer pipe offers the advantages of both metal and plastic.

Metals' negative aspects such as corrosion, toxicity, scaling and rigidity are eliminated by the PE-X layers surrounding the pipe.

Contact between the brass fitting and the aluminum pipe is prevented thanks to a seal which fits between the end of the pipe and the brass fitting. This means that the system is entirely protected against electro chemical corrosion.

Pexal is fully approved to AS 5601 for natural gas and LP gas applications.
Licence number: IP00083 AS4176 SPEC 438

Pexal Cross-Section

DR brass fittings allow the system to be installed below ground or in concrete with no extra work. As Pexal uses DR brass, the fittings do not need to be wrapped in tape before being buried. For under ground installation allow 450mm cover and a yellow marking tape must be buried 100mm above the Gas pipe.

Pexal Pipe is manufactured using the highest quality materials, this process allows the highest temperature rating of 80 °C ambient temperature. The pipe has an intermediate layer of longitudinally but-welded aluminum.

A Dewalt 18 Volt Hydraulic Crimping Tool is required to use the Pexal system. This tool applies a pre-determined amount of force to every joint, therefore not leaving room for human error.

The Pexal Gas piping system can be run directly to any Gas Meter, using a crimp to 25mm MI Elbow. Any Pipe subject to Ultra Violet light must have protection against degradation. This can be as simple as painting with UV stable paint of lagging with a UV stable material.

Pexal pipe comes in lengths and coils:

  • All sizes are available in straight lengths, which are 5m long.
  • 16mm and 20mm are available in 100m coils.
  • 26mm and 32mm are available in 50m coils.
  • It is recommended to use coils, therefore reducing the amount of fittings required.

This system can be clipped using standard plastic clips for most types of cross-linked pipes, for example Rehau, Pro-fit and Yorkflex.

One of the key advantages of Pexal gas pipe is the amount of pipe and fittings that have been approved for use. View the approvals at SAI GLOBAL .
