Merits of High-Density Polyethylene Pipes
A known fact is that high-density polyethylene pipes are thermoplastic pipes that are made from material that can be melted and reformed, and it has many useful features like rugged, durable, and flexible. One of the downsides of using metal pipes is the issues of corrosion that occurs both inside and outside the pipe and affects the hydraulic efficiency of the metal pipes. A lot of cities treat the water to decrease the rate of rust formation and pitting that occurs with metal pipes, but some people prefer to use expensive cathodic protection, sleeving, or plastic coating to extend the life of the pipe. The truth is that unlike metal pipes high-density polyethylene pipes do not rot, corrode, or rust is resistant to biological growth which means extended service life and longer savings in times of money.
A known fact is that high-density polyethylene is ductile and flexible, and it has a high resistance to fatigue because it is designed and pressure rated to handle the regular events that are a standard feature in water distribution systems, and this will enable the person to use a thinner wall high-density polyethylene pipe compared to other kinds of plastic piping. A high-density polyethylene pipe is a safe and durable product that is right for the piping infrastructure, and the estimated life is between half a century to a whole century depending on how it was applied, installed, and designed.
A popular study showed that municipal water departments lose about 16% of water due to leaking joints and in some places the water loss can go up to 50%. It is good to state that the old water infrastructure was joined using a bell and spig or mechanical joints that have a leaking issue which leads to cities losing money in the process, but new systems that have high-density polyethylene piping systems are joined using heat fusion to make the joints leak proof.
These truths are HDPE piping systems can only be joined using heat fusion welds, and heat fusion involves the heating of two HDPE surfaces when bringing them together to create a permanent, leak-free, monolithic system. It is vital to note that the fusion process for high-density polyethylene is different from other fusion processes since it originates from been used in the natural gas industry where is used by close to all gas distribution piping in America to join their polyethylene pipes.
Apart from high-density polyethylene being joined with heat fusion, it can be joined with other material like a stab or mechanical fittings that are widely available in the market to suit every kind fitting and pipe size and application.
