There are various materials that can be used for pipe fittings – all having their own advantages and disadvantages. In today’s guide we shall look at HDPE pipe fittings – what they’re used for as well as other important information.

What they’re used for

HDPE (High Density Polyethylene) is a form of plastic that is commonly used for pipe fittings. Due to its flexibility it is used in a variety of situations including industrial, underwater, mining, gas extraction, commercial and municipal purposes.

They have the capability to carry a range of materials such as waste, chemicals, slurries, potable water, hazardous waste, compressed gases, oils and cables. They also have a range of agricultural applications.

Types and Sizes

HDPE pipe fittings come in a huge range of types and sizes. Due to their mostly industrial purposes, they come in much larger sizes than popular domestic pipe fittings such as PVC and copper.

HDPE pipe fittings are usually available in both molded and fabricated styles.

Some of the most common types of HDPE pipe fittings are similar to those that are available for other materials. These include tees, bends, puddle flanges and more. There is practically an HDPE pipe fitting for every potential purpose.

Advantages and Disadvantages of HDPE Pipe Fittings

There are a many advantages to using HDPE pipe fittings. In fact, it is one of the most durable and cost-effective materials available today.

It is incredibly strong and tough and can withstand huge pressure and unlike other popular materials it does not rot, rust or corrode. Materials such as PVC are fantastic for use around the home, however they are not resistant to acids and chemicals. HDPE pipe fittings on the other hand are resistant to corrosion from acids, bases and salts – making them ideal for agricultural and industrial purposes.

Similar to other plastic-type pipe fittings, HDPE offers a very smooth interior meaning that its flow properties are superior to materials such as concrete, steel and iron. The smooth interior also prevents bacterial growth, blockages within the pipe and the formation of scale.

Because of these advantages it means that the up-keeping costs of HDPE pipe fittings is minimal – as they have a long life span and rarely need repairing or replacing.

The versatility of HDPE pipe fittings means that they are able to be used in a variety of situations including above ground, underground, underwater and as surface pipes.

HDPE pipe fittings are also very lightweight which poses a variety of benefits. The plastic material is much lighter than alternative materials such as metal or concrete. This makes it much easier to maneuver and install and also cuts down shipping and transportation costs – particularly when purchasing in bulk.

Once again, in comparison to PVC pipe fittings, HDPE can withstand impact a lot better than PVC. It is structurally much stronger and better resists cracks and breaks.

When using HDPE pipe fittings for transporting water, it is a fantastic choice as the allowable water leakage from them is zero as opposed to 10 – 20 percent typical leakage rates from PVC and ductile iron pipes. The joints between HDPE pipe fittings are much stronger than other materials and minimize leakage.

There are minimal disadvantages to using HDPE pipe fittings – when used for their specified purposes. The main disadvantage to HDPE pipe fittings is that it is less forgiving to human error than other materials. If HDPE pipe fittings are not carefully and professionally fitted then the life span and reliability of the pipelines can quickly deteriorate.

In comparison to its most popular competitor – concrete – it is not quite as structurally strong. However, it has many other advantages that help outweigh the disadvantages.

Where Can You Find Them?

Due to the lightweight nature of HDPE pipe fittings they are very commonly available for sale on the internet. Postage and shipping is comparatively low, and you can find a huge variety of fittings to suit your needs online. The internet also offers much lower prices on HDPE pipe fittings than you will find in store.

However, if you do wish to see the HDPE pipe fittings in person then you can find a wide range of hardware and plumbing specialist stores across the USA.
