What You Need To Know HDPE Pipes

HDPE pipes or high density polyethylene pipes are pipes that are made from high density polythene thermoplastic which is made from petroleum. The material is known for its large strength to density ratio.

Unique features of the pipe

The pipe has a number of unique features. One of the features is that the unit is very flexible and as a result it can be used in a number of applications.

Another great feature is that the pipe can be melted and re-solidified for unlimited number of times without losing the favorable qualities. Due to this, most of the HDPE pipes are made to be “butt welded.” This is where the ends of the pipes are melted, pushed and held together thus forming a single pipe.


The units come in different sizes where they are given different DR ratings. The DR rating is the outside diameter. The DR ratings range from DR 32.5 to DR 7.


The units come with different colors. The different colors are: blue which is used in water distribution, red used in fire pipes, green used in sewers, yellow used in gas, and purple which is used in reclaimed water.

How to install the pipes

The pipes are meant to be installed underground. Here you need to dig a trench and lay the pipe in it and then backfill the trench. The most common pipes that are installed underground are: drainage, water distribution, and gas distribution pipes.

You can also install the pipes inside buildings. Here you need to bend the flexible pipes around heating pipes, beams, chimneys, and other obstructions.

If you want to construct systems to handle chemicals or other liquids in an industrial setting, you need to install the pipes overhead. Here you need to uncoil the pipes into the proper layout and run them along walls or beams to a ceiling.

You should them fasten the pipes with clamps where needed. If you want to connect them you should use heat welding or mechanical connectors.

To seal the joint you should use compression fasteners which usually tighten inside of the pipe and as a result seal the joint.


This is what you need to know about HDPE pipes. You should note that there are many people who produce substandard units and sell them to unsuspecting customers. To be on the safe side you should always ensure that you do your research and only buy from a reputable seller.
