High-density polyethylene pipes (HDPE) are one of the world’s most popular pipes across a variety of industries.
For example, HDPE pipes are used in civil engineering, building and construction, agriculture, industrial projects, mining, and marine/aquaculture (to name a few). All of these industries opt to use this type of pipe because HDPE pipes are strong, durable, flexible and lightweight. Additionally, they are more environmentally advantageous than other kinds of piping. Plus, they are affordable!
If you are considering buying some or simply want to learn more, read on for seven essential things to know about HDPE pipes and fittings, and what to look for when purchasing them.
1. They are incredibly tough.
HDPE pipes are flexible plastic pipes that are often employed during fluid and gas transfer and to replace ageing pipelines.
Polyethylene is a reliable and incredibly durable material; however, HDPE plastic is an even denser version of polyethylene that has more rigidness and crystalline structure.
Due to the high level of impermeability of HDPE, this material is ideal for high-pressure pipelines. In fact, HDPE pipes boast the lowest servicing rate per mile per year when analysing other pressure pipe materials that are frequently used.
2. They are suitable for a variety of applications.
Due to their impressive strength-to-density ratio, HDPE pipes and fittings are often utilised in a variety of systems that require corrosion-resistant piping.
For example, HDPE pipes are suitable for food production, and for carrying water, wastewater, chemicals, and hazardous wastes. These pipes also have long serviced the gas, oil, and mining industries as they are resistant to corrosion and low weight.
Increasingly, HDPE pipes are being adopted around the world in eco-building projects because they are composed of recycled materials, and are also 100 percent recyclable. Additionally, HDPE is approved for use in schools and healthcare facilities.
3. They provide a host of benefits.
In addition to being incredibly tough, HDPE is also very flexible, which is why it is particularly beneficial for bending pipes and absorbing any pressures or vibrations that occur in the soil or the environment surrounding it.
Moreover, HDPE is resistant to corrosion, chemicals, impact, and adverse weather. This material is also rot-, mold-, mildew- and insect-resistant, which is why it is ideal for underground pipes.
4. They come in a variety of sizes and shapes.
HDPE is highly malleable, which allows it to be reshaped into any required specifications.
For this reason, HDPE pipes come in a variety of sizes and shapes, so you are guaranteed to find the right style that’s suitable for your project.
To reshape HDPE, the material is forced into a mold under high heat and pressure. Then, once the material has cooled down, the mold is opened, and the HDPE has been transformed. No matter what size or shape the HDPE pipe is, it will still be lightweight enough so it is easy to handle and transport.
5. They are joined by a fusion-welded system.
In order to join HDPE pipes, you can use a welding system such as butt, electrofusion or socket welding. During this process, the joints warm the tube so it becomes as secure as possible and eliminates the need for other seals or jointing chemicals.
This is a significant benefit of HDPE pipes as jointing chemicals can create environmental health issues and have a higher likelihood of collapsing. Additionally, by welding the pipes, there is no need for thrust restraint blocks or anchors, as the joints are entirely load-resistant. This, in turn, decreases material costs and the required installation time.
6. They are easy to identify.
If you want to know whether you have HDPE pipes, you simply have to look for a few defining factors. The easiest thing to note is that high-quality pipes (such as HDPE pipes) will have a smooth inside and outside surface with no dents, scratches, or other defects.
7. They are the best option economically.
For those involved in the agriculture, mining, building and construction, automotive, and packaging industries, HDPE pipes are generally the preferred option. This is because they provide a lot of benefits while also being the most economical choice when examining materials, installation costs and performance.
What to Look For When Purchasing HDPE Pipes and Fittings
If you are considering purchasing HDPE pipes and fittings, then there are a few things you need to consider. First, you must ensure that you know the exact size and shape of the pipe you require. This is crucial to ensure that your purchase fits without any issues. If you are unsure of the size and shape you need, make sure to reach out to an expert who can advise you on the best options for the project.
Additionally, you want to check the quality of the materials as this is essential for ensuring that you have a high-performing pipe. For this reason, you want to ensure you are purchasing your HDPE pipes and fittings from a reputable plastic pipe supplier who can assure you concerning the quality of their products.
What to Look For in an HDPE Pipe Supplier
When looking for an HDPE supplier, there are a few things that you should expect. First, any reputable supplier should be well connected in the industry and should understand the market enough to be able to advise you on the best products. Additionally, they should have an impeccable service record, as a company that prioritises customer service is unlikely to be selling low-quality products. Whatever you do, don’t compromise on quality and always purchase from a company that you can trust.
No matter why you need an HDPE pipe and fitting, it is highly recommended that you reach out to your local plastic pipe supplier, as they will ensure you get the right product for your house or building.
