Black Pipe
Black Pipe
Black poly pipe offers a magnificent array of benefits, compared to other materials. These benefits include resistance to damage, impacts, chemicals and weather.
Other factors favouring black poly piping are:
- ease of installation
- long life in excess of 50 years
- and the ability to be used in trenchless construction methods.
What does SDR11 HDPE mean?
SDR11 stands for the size dimension ratio of 11. You must divide the OD(mm) of the HDPE piping by the SDR, to give you the pipe wall thickness. E.g. divide 180mm(OD) by 11, giving a wall thickness of 16.4mm.
With HDPE piping, SDR 11 gives you a pressure rating of PN16, or 16 bar.
