Flexibility and leak proof jointLeak proof at butt fusion jointingFlexibility
Due to its flexibility, HDPE pipe can fit to the contour of physical environment without utilizing extra joint of fitting. HDPE pipe’s radius of curvature is approximate 25‐40 times of the diameter.
This characteristic makes HDPE pipe suitable for submarine project or any rough condition.
Typical jointing method for HDPE pipe. Pipe and welded joint are homogeneous, and the strength of the welded joint is equal or more than the pipe.
Welding can be done aboveground beside the trench, thus, avoid the problems associated with underground welding including water and old pipe obstructions.

PE CharacteristicLight weightLow Friction Loss
Compare with the same pipe dimension, HDPE pipe is approximately four times lighter than concrete and steel pipe.
This characteristic saves transportation cost and installation and improve speed of work at site.
With low friction, HDPE pipe can transport more quantity of water compare to the other pipes with the same diameter.
With the same flow rate requirement, one can substitute smaller HDPE pipe for the said purpose.

Lowest Vulnerability to earthquakes
The ASCE 2002 document tabulated the vulnerability to earthquakes of various pipe materials:
Pipe material Vulnerability to earthquake
PE Low
Ductile iron Low and Low‐moderate
Steel Low and high
Concrete cylinder Low‐moderate, to High
PVC Low‐moderate, to Moderate
Cast Iron Moderate‐high, to High
Vitrified Clay Moderate‐high, to High

Year 2030 The Urban Challenge Focus on “The Urban Challenge”
Year 2030, it’s estimated that 5 billion people or 60% of the world’s population will inhabit urban areas.
Demand for Fresh Water
Ground water sources can no longer meet the demand due to depletion or pollution.
Raise resource efficiency and make water service provision cheaper and easier to provide for large number of people
Water management is at the centre of the sustainable city boom.
