Polyethylene pipe comes in many different colour options, but each colour is according to the HDPE pipe colour code. The purpose of the different colours on HDPE pipe is to identify the liquid or gas inside the pipe. The following list of PE pipe colours may help you identify what colour you need. Also if you need help identifying a pipe not listed here, please speak to our team on 1300 270 270.
Note: poly pipe stripe colour coding and requirements may differ in other countries or states. Check with a qualified engineer if you are unsure of PE pipe stripe colour coding.
HDPE Pipe Striping and Colour Coding Guide:
HDPE black pipe no stripes – may be used for all applications except for fuel gases (Acu-Black HDPE pipe).
HDPE black pipe with blue stripes – drinking water line/potable water pipeline (Acu-Water HDPE pipe).
HDPE black and yellow pipe – black with yellow stripes or full yellow jacket – fuel gases, process gases, liquefied gases under pressure (Acu-Gas HDPE pipe).
HDPE pipe black with red stripes – water dedicated for fire extinguishing supply lines. (Acu-Fire HDPE pipe).
HDPE pipe full white jacket – communications conduit (Acu-Comms HDPE pipe).
HDPE pipe black with lilac stripes (or black with purple stripes)- recycled or reclaimed water pipes (Recycle-Tech HDPE pipe).
HDPE pipe full orange jacket – electrical conduit (Acu-Power HDPE pipe).
HDPE pipe full white jacket – above ground co-ex pipelines (Acu-Therm HDPE pipe).
HDPE pipe black with cream stripes – sewer pipes (Acu-Sewer HDPE pipe).
HDPE pipe black with brown/red stripes – rural imperial-size low-pressure pipe (Acu-Rural HDPE pipe).
Because polyethylene pipe can be manufactured in many different colour options, the outside colour of HDPE pipe is used to identify the pipeline’s contents. What do the different colours on HDPE pipe mean? The purpose of striped piping or coloured piping is to identify the contents of the pipeline. Poly pipe colour coding practices and requirements may be different outside of Australia. Confirm with a qualified engineer if you are unsure of pipe colour coding requirements.
