Benefits of Using HDPE
High Density Polyethylene Pipe (HDPE) is a thermoplastic pipe made from material that can be melted and reformed. It is rugged, flexible, and durable. It has outstanding chemical and environmental stress crack resistance.
Relative to existing infrastructure, like ductile iron, concrete or PVC, HDPE seems like a new product. In reality, it has been successfully used in a wide variety of piping applications for over 50 years.
The outstanding physical and performance benefits of HDPE pipe make it the perfect choice for your piping systems.
Corrosion is one of the most costly problems associated with metal piping systems. It occurs both inside and outside the pipe and affects hydraulic efficiency. Many cities treat their water to help slow rust and pitting that is inevitable with metal pipes. Others choose costly cathodic protection, plastic coating, or sleeving to try and extend the service life of the pipe.
Unlike traditional metal infrastructure products, HDPE pipe does not rust, rot or corrode. It is resistant to biological growth. This means an extended service life and long term cost savings.
HDPE pipe is flexible and ductile, not rigid. It has outstanding resistance to fatigue. Unlike other plastic pipes, it is designed and pressure rated to handle the kind of occasional and recurring surge events that are common in water distribution systems.
In many instances, this will enable you to utilize a thinner wall HDPE pipe as compared to other types of plastic piping.
HDPE pipe is a safe and durable product ideal for your piping infrastructure. The service life of HDPE is estimated to be between 50 to 100 years, depending on application, design and installation.
An independent study reports that municipalities in 43 states average a water loss of 16% due to leaking joints. Some report water losses as high as 50%.
Traditional infrastructure piping is joined with bell and spigot or mechanical type joints and all acknowledge a specified leakage factor. Not only is our most precious resource being lost, but leaking pipes are costing our cities money. HDPE piping systems can be joined with heat fusion to produce permanent leak free joints.
HDPE piping systems can be joined with heat fusion welds. Heat fusion involves the heating of two HDPE surfaces then bringing them together to form a permanent, monolithic, leak-free system.
Unlike the fusion process developed for other plastics pipes, the fusion process for HDPE is proven and has been used by the natural gas industry for over 40 years. Approximately 95% of all gas distribution piping in the United States is polyethylene pipe joined by heat fusion.
Fusing HDPE pipe is not difficult and personnel can be trained in the process.
