External multilayer gas piping

Thursday December 15 2016

Multilayer proprietary pipe is a popular choice of material for gas consumer piping. However, the VBA has become aware that practitioners are at times failing to protect these pipes from UV degradation and physical damage in accordance with the relevant plumbing standards.

The gas installation standard AS/NZS 5601.1: 2013 Gas Installations Part 1: General installations, requires multilayer piping to be protected against degradation from exposure to UV and physical damage. Typical means of protecting multilayer pipe includes sleeving or wrapping with a suitable protective material.

The VBA advises practitioners to:

  • refer to the supplier for advice and evidence of resistance to UV light
  • refer to the product manufacturer for information on the limitations to piping systems and product specifications.
