IS HDPE PIPE SUITABLE FOR WATER SUPPLY?

HDPE pipe is well-suited for Agriculture water supply applications. Beneficial properties of HDPE piping systems include:

Leak-free Fused Joints :
Fused joints eliminate potential leak points and reduce installation time. The heat-fused joints are as strong as the pipes themselves, leading to long-term, leak-free operation with little-to-no maintenance required.

Chemical Resistance :

In potable water applications, it’s essential that chemicals will not leach from the piping material into the water. Studies show that HDPE pipes are safe for potable water applications and Arham’ products are certified by NSF on an annual basis. Disinfectants such as chlorine and chloramine are approved for use in HDPE pipe. HPDE pipe will not corrode or tuberculate, maintaining flow velocities over the life span of the system.

Durability and Flexibility :

Unlike more brittle piping materials such as PVC and ductile iron, HDPE pipe is a more durable and flexible pipe material with a bend radius up to 20 times the pipe diameter. This allows the HDPE pipe to conform to an imperfect installation path without the need to add costly fittings and excessive pipe joints.

Extreme Surge Tolerance :

HDPE pipes are the most resistant to surge and fatigue of any potable water piping systems. HDPE pipe can handle occasional surges up to 2 times its’ pressure rating, and recurring surges up to 1.5 times its’ pressure rating with no risk of stress damage to the pipe. HDPE pipe can handle much higher flow velocities which result in lower pressure surges compared to other potable water piping systems.

Temperature Resistance

HDPE pipe can handle fluid and environmental temperatures ranging from -40°F to 140°F, making HDPE water pipe suitable for use with hot or cold water in many different environments. HDPE pipe can handle repeated freeze/thaw cycles without incurring damage to the pipe.

Installation

HDPE pipe is cheaper to install than other potable water piping systems. With its’ narrower trench widths and its ability to be installed with trench-less technologies (directional drilling, pipe bursting, slip-lining, and compression fit lining), making HDPE pipe the most commonly used piping material for trenchless installations. Compared to other installation methods, trench-less installations reduce disturbances to surrounding environments and greatly reduce the amount of construction restoration, leading to a cost savings up to 65%.
