HDPE pipes are a commonly used type of pipes in Lahore, Pakistan. There are various companies that manufacture these types of pipes due to the high demand for these pipes in various industries.

The main purpose of these pipes is to transfer gas or fluids from one place to another. These are made up of a flexible material that helps them do their task with ease. While there are many manufacturers of these pipes in Lahore, Pakistan – people sometimes need greater knowledge of these pipes.

In this article, you will find out various facts about HDPE pipes.

What are HDPE pipes?

HDPE or high-density polyethylene is a popular type of pipe. It is a synthetic polymer that is made up of petroleum. It is usually used to produce plastic bottles, corrosion-resistant piping, etc.

As the name suggests, HDPE pipes have a high density and great strength. Due to this reason, they keep on doing their work for over 50 years. They have various characteristics that make these pipes the first choice of many people.

These pipes are non-toxic and odorless; that is why they have the greatest demand and supply all around the globe. Let’s take a look at some of the other characteristics these pipes have.

They are strong

As mentioned before, HDPE pipes are extremely strong. They can take all types of loads – dynamic or static. Moreover, they have high resistance towards any type of impact.

Furthermore, these are your best choice in freezing conditions as they do not break under such conditions. Also, they are made for rough use. Thus, they do not get affected by the rough handling and traffic.

They are non-hazardous

As these pipes are non-toxic and inert, they are also non-hazardous. This is the reason why they are commonly used to transfer portable water.

They are corrosion resistant

One of the best characteristics of these pipes is that they are resistant to electrolytic and galvanic corrosion. This is why they are majorly used for underground installations.

They are passive to chemicals

These pipes are a great option for handling acids and alkalis. This is because they are made up of material that is great at resisting chemicals. Therefore, these pipes are used commonly in chemical plants – due to their resistance to corrosive chemicals.

They have a lightweight

As compared to the other pipes used, HDPE pipes are extremely lightweight. Due to this reason, it is easy to transport and install them. Hence, the cost for installation and transportation is a lot less as compared to the other pipes.

They have a smooth surface

The internal and external surface of the HDPE pipes is very smooth. Thus, there is no effect of friction when fluids are flowing through them. Also, due to their smooth surface, they allow solid particles to easily pass through with the fluid.

They are flexible

Another amazing characteristic of HDPE pipes is that they are extremely flexible. They can be bent in any direction without breaking. Therefore, long lengths of pipes that have small diameters can easily be transported in the form of coils.

They can easily be installed

As mentioned above, HDPE pipes are extremely lightweight. This is why they can be easily installed. Also, as they do not need heavy machinery for installation, they can be installed pretty quickly – saving a lot of time.

Their electric resistance is high

All around the country, these pipes are commonly used as electric conduits. This is because they have high resistance to electricity. Furthermore, no stray currents can enter these pipes from an external source – making them safe.

They have a higher durability

As compared to the other common;y used pipes such as PVC, steel, cement, GI, etc. HDPE has a greater life span. This is mainly because of the material used in these pipes that make them last for more than 50 years.

What raw material is used in manufacturing HDPE pipes?

The main raw material used to manufacture these pipes includes HDPE pellets. These are made up of virgin polyethylene granules and HDPE that have been recycled.

The polythene materials used are made by polymerization of ethylene. This is obtained from oil. Polymers have different characteristics and range from high density to low density.

The HDPE compound good for water pipes is made by adding various necessary additives along with polymer powder under controlled circumstances. These additives give protection to polymers against the process of degradation that can take place during the manufacturing process.

The sizes of HDPE pipes

The HDPE pipes, like any other pipes, come in different sizes. Their diameter usually ranges from 16mm to 2000mm. However, there are unlimited sizes available for these pipes. Given below is a list of the sizes available for HDPE pipes.

  • 32mm
  • 63mm
  • 90mm
  • 110mm
  • 125mm
  • 160mm
  • 180mm
  • 225mm
  • 250mm
  • 280mm
  • 315mm
  • 355mm
  • 400mm
  • 450mm
  • 500mm
  • 560mm
  • 630mm
  • 710mm
  • 800mm
  • 900mm
  • 1000mm
  • 1100mm
  • 1200mm

The internal bore of these diameters depends on the SDR of every pipe. You can get non-standard pipe sizes for certain specifications if you need them!

Different manufacturers in Lahore, Pakistan, manufacture pipes in different sizes with different sizes diameters. All you have to do is look for the one you need. You can also take consultation from these manufacturers to understand the size you need for your pipes.

The top uses of HDPE pipes

Earlier in the article, we discussed the various characteristics that HDPE has. Keeping in mind those characteristics, there are various industries that use HDPE pipes. Some of these industries include the fertilizers industry, paper, and pulp industry, power plants industry, liquified natural gas industry, glass industry, etc.

The application of these pipes is usually for acid/caustic lines, organic and inorganic chemicals, cooling water, pit dewatering, etc.

Given below are some of the uses of the HDPE pipes in the industry.

Agricultural use

HDPE pipes are an essential part of the agricultural industry. They are used for various purposes in this industry. These include flow line irrigation, water supplies, lift irrigation, and drip irrigation, to name a few.

Submarine and underwater pipelines

In this industry, they are used as pipelines to drain the sewage water, saltwater intake lines, canal crossing underwater, etc. These pipes are used for these purposes because of their resistance to corrosion and chemical resistance, etc.

Gas or compressed air systems

These pipes are also used to transport and distribute sewage gas in air conditioning and ventilation ducts, transporting natural and coal gas, etc.

Hydro transport systems

HDPE pipes are used to dispose of iron ore waste. Furthermore, they are used to handle the ash of a boiler, to handle cement, etc. They do this all because they have resistance to corrosion.

Transportation of chemicals and edibles

As these pipes are chemical resistant and do not corrode, they are used to transport fluids like milk, edible oils, alkalize, etc. They are also used to transport any corrosive chemicals.

To wrap it up!

HDPE pipes are the most common type of pipes used in various industries. This is mainly because of the outstanding qualities that make them stand out in front of other pipes.

As they have a great demand, many manufacturers in Lahore, Pakistan, are manufacturing them to make it easier for industries to use them to their advantage.
