  HDPE pipe is well-suited for potable water supply applications.

   

  Beneficial properties of HDPE piping systems

  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. Disinfectants such as chlorine and chloramine are approved for use in HDPE pipes. HPDE pipe will not corrode or tuberculate, maintaining flow velocities over the life span of the system.

  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.

  Extreme Surge Tolerance

  HDPE pipes are the most resistant to surge and fatigue of any potable water piping system. 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 results in lower pressure surges compared to other potable water piping systems.

  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.

  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 is 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 cost savings of up to 65%.

  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.

  Black HDPE Water Pipe Features

  HDPE water supply pipelines are widely used, mainly because they have characteristics that other pipelines cannot match:

  1. It is easy to butt welding and electrofusion welding to form a closed anti-seepage system. When laying along the trench, it can reduce the amount of trench excavated earthwork and reduce accessories.

  2. No external protection is needed for buried pipelines with strong wear resistance and excellent hydraulic performance. It can be applied to earthquake and soil settlement areas in mining areas, and it can also be laid at the bottom of rivers by the sinking method.

  3. Lightweight and easy to install and handle.

  4. Good environmental adaptability and frost resistance. It can be used for indoor and outdoor water supply pipelines.

  5. Resistant to chemical corrosion, internal, external, and microbial corrosion, strong corrosion resistance, and healthy. It is suitable for transporting acidic and alkaline substances, sewage, natural gas, coal gas, and other substances.

  6. Easy to recycle.

  7. Long service life, with a service life of more than almost 50 years.
