PIPE Technical Information

Piping
    PE-X piping is manufactured from high density crossed linked polyethylene . To conform to Australian Standard AS/NZS 2492, the base material used in the manufacture of PE-X pipe, can be cross-linked by using one of three methods; by the peroxide (PE-Xa), Silane (PE-Xb) or electron beam (PE-Xc) cross linking process.

    The great advantage of BUSH PE-X pipe is that it can be used with BUSH Pull-On, BUSH Crimp-On and BUSH Push-On fittings to complete three systems all using the  same pipe but utilising three different jointing methods. 

    The piping is available in three colours. The colours help to identify the pipe application. It
is recommended that unprotected pipe not be exposed to direct sunlight on a permanent basis.
Black -  Suitable for potable hot & cold water plumbing in domestic and commercial
              applications.

Red -   Suitable for potable hot water plumbing in domestic and commercial applications

purple-  Suitable for recycled, non potable water.

green-  Suitable for rainwater.

pressure ratings

   Pipes for water applications are classified in terms of the nominal pressure rating (PN) at water service temperature of 20°C. BUSH PE-X Pipe has a pressure rating of PN20 and a nominal working pressure of 2,000kpa at 20°C. The following table shows the relationship of the pipe working pressure and pipe material temperature (PMT)

Temperature ratings

   PE-X pipe is suitable for use at temperatures up to 100°C however; continuous long term operation should be between -50°C and +70°C under working pressure as detailed above.
