Areas of Use of HDPE Pipes

HDPE pipes have been increasingly used in the construction industry and industrial applications in recent years. These pipes, which are produced from high-density PE100 class raw materials, are used in many different fields due to their chemical resistance and high pressure resistance.

They can be used in different fields such as drinking and drinking water pipelines, pressure drainage and wastewater pipelines, pressure irrigation lines, underground and above ground applications, gas pipelines, industrial pipelines.

The advantages of HDPE pipes include high durability, corrosion resistance, flexibility, health suitability and UV resistance. For this reason, they are especially preferred for drinking water lines and industrial applications.

Usage areas of HDPE pipes are expanding day by day and they are used more and more in the construction sector. This is because they are more economical and last longer than other pipe materials. HDPE pipes are also very easy to install and can be applied quickly.

If you want to benefit from the advantages offered by HDPE pipes, we recommend you to work with an expert team like us for a correct application.

Installation Methods of HDPE Pipes

The installation of HDPE pipes is easier and faster than other pipe materials. Therefore, the use of HDPE pipes has been increasing rapidly in recent years. Different methods can be used for the installation of HDPE pipes. Which method will be used may vary depending on the characteristics and needs of the pipeline.

Here are some methods used for the installation of HDPE pipes:

1. Electrofusion Welding: This method is one of the most widely used methods for joining HDPE pipes. Electrofusion welding allows two pipes to be connected by means of electrodes at the end. The electrodes are placed on the pipe ends and the pipes are connected by applying an electric current. This method provides high safety and robustness.

2. Seamless Pipe Assembly: This method allows HDPE pipes to be joined by welding method. The ends of the pipes are connected to each other using a welding machine. This method requires welding machines of different sizes depending on the pipe diameters used in pipelines.

3. Mechanical Connection: This method allows HDPE pipes to be joined mechanically. The pipe ends are connected to each other using special fittings. This method is a quick and easy installation method, but less robust than other methods.

The installation of HDPE pipes, if done correctly, offers a reliable and long-lasting solution for pipelines. However, it is extremely important that the installation process is carried out professionally and the appropriate equipment is used. Improper installation of the installation process can cause problems such as water leaks, explosions and damage to pipelines. Therefore, it is highly recommended to use a specialized equipment and an experienced one for the installation of HDPE pipes.

Advantages of HDPE Pipes over Other Pipe Materials

HDPE pipes have many advantages over other pipe materials. These advantages are:

1. Lightweight: HDPE pipes are lighter than other pipe materials. Therefore, it is easier to transport and assemble.

2. Flexible: HDPE pipes have the feature of high flexibility. Thanks to this, it is more resistant to impacts and deformation.

3. Durable: HDPE pipes are produced from high density PE100 grade raw material. Thanks to this, it is highly resistant to chemicals and corrosion.

4. Long Service Life: It has a service life of at least 50 years at rated operating pressure.

5. Easy to Weld: HDPE pipes can be easily joined by electrofusion welding method.

6. Sealed: The welded connections of HDPE pipes are sealed.

7. Suitable for Health: HDPE pipes do not change the smell and taste of water. They also do not contain substances harmful to health.

8. It is Environmentally Friendly: HDPE pipes are a recyclable material.

These advantages of HDPE pipes cause them to be preferred in many fields such as water, waste water, gas, oil.

Maintenance and Repair of HDPE Pipes

HDPE pipes have a structure that requires less maintenance and repair than other pipe materials. This is because HDPE pipes have excellent corrosion resistance, which means that they are not exposed to problems such as rusting and abrasion over time.

But although it is an advantage that HDPE pipes are durable and do not need maintenance, some problems may be encountered over time. These problems can usually occur due to the completion of the pipe’s service life, damage caused by external factors, or faulty applications.

Maintenance and repair operations of HDPE pipes should be carried out by a professional team. Depending on the type and magnitude of the damage caused to the pipe, the repair process can be performed by different methods. For small scale damage, patching or welding is usually performed, while for larger damage, a complete replacement of the pipe may be required.

Some important tips for the maintenance and repair of HDPE pipes are as follows:

• Regularly check the damage to the outer surface of the pipe and take the necessary measures.

• Immediately notice any leaks or other problems that occur in the pipe and intervene.

• Pay attention to the usage temperatures of HDPE pipes and do not exceed these temperatures.

• When repairing HDPE pipes, use the right equipment and have a professional team do the process.

As a result, although the maintenance and repair operations of HDPE pipes are performed less frequently than other pipe materials, some problems may be encountered over time. Therefore, it is important to regularly check and maintain the pipes. These processes will extend the life of the pipe and provide longer use.

Standards and Certificates of HDPE Pipes

HDPE pipes are manufactured and used in accordance with standards worldwide. These standards aim to ensure that pipes are manufactured, installed and used in a safe and high quality manner. Furthermore, the fact that HDPE pipes have certain certifications provides additional assurance to consumers about the quality and safety of the product.

International standards for HDPE pipes include EN 12201, ISO 4427, ASTM D3350, ASTM F714 and AS/NZS 4130. These standards provide detailed information on the properties, dimensions, test methods and production methods of HDPE pipes.

Certificates of HDPE pipes include NSF, WRAS, Kiwa, FM, UL and TSE certificates. These certificates show that HDPE pipes have passed certain tests and have a certificate of conformity. NSF and WRAS certificates indicate that HDPE pipes are suitable for drinking water applications, while FM and UL certificates indicate suitability for fire protection systems.

Producing and using HDPE pipes in accordance with standards and certifications provides consumers with a safe and quality product. In addition, the fact that HDPE pipes have certificates gives project managers and installers more confidence in the quality and suitability of the products.

Different Sizes and Pressure Classes of HDPE Pipes

HDPE pipes can have different sizes and pressure classes. This depends on the usage areas and needs of the pipes.

Diameters of HDPE pipes generally range from 20 mm to 1600 mm. However, pipes with larger diameters can also be produced in line with the requirements. The wall thickness of the pipes can also be different and is usually determined according to the diameter of the pipe and its intended use.

The pressure class of HDPE pipes is also important. HDPE pipes can generally have pressure classes such as PN4, PN6, PN8, PN10, PN12.5, PN16, PN20, PN25. The pressure class of the pipes is selected according to the pressure of the liquid to be transported in the pipe.

Different sizes and pressure classes of HDPE pipes are suitable for many applications in various industries. Drinking water lines, waste water lines, gas pipelines, industrial pipelines, mining pipelines and many more applications can be constructed with HDPE pipes in different sizes and pressure classes.
