​​HDPE And Thermoplastics

The two most commonly used materials for piping applications in most parts of the world today is PVC (polyvinyl chloride) and HDPE (high-density polyethylene).

 

Despite questions being raised in terms of environmental and human health*, PVC is used in a wide variety of applications in addition to piping (which constitutes around 50% of its use), including, housing materials, office equipment and even children’s toys and plastic medical devices.

 

HDPE, by comparison, is a better choice for the environment – it’s chlorine-free, doesn’t produce dioxin as a by-product, has less additives and a higher recycling potential. HDPE is also:

• Highly resistant to abrasion and chemicals

• Less susceptible to surge shocks

• More flexible, with seamless joints.

​​

Here are more good reasons to choose HDPE pipes and fittings over other materials:

• Prolonged lifespan – high-quality HDPE can last as long as 100 years!

• Recycled HDPE can be used to manufacture piping solutions, saving energy in the manufacturing process and keeping material out of the waste stream

• HDPE joints are merely fuse welded (melted) together – no toxic solvent glues required

• HDPE can be delivered in longer lengths with fewer joints, which means less potential for leaks

• Butt fusion welding results in tighter, stronger joins than those of bell and spigot or solvent glue joints, which means less potential to fail

• Lower cost, when factoring in joint failure, potential leaks and associated water loss over a fifteen year period

• HDPE lengths and flexibility means that trenchless installations are possible under certain circumstances

• Highly durable and low-maintenance.
