  These are corrugated HDPE tubes used for underground installations. They are designed to withstand external pressure, impact, and UV radiation. The ducts have ribbed exteriors that provide strength and stability when buried underground. They are commonly used in electrical and telecommunications applications.

Functions and features of HDPE tube

HDPE tubes are used in different industries for various applications because of their outstanding features. Some of the industries include; agriculture, construction, telecommunications, wastewater management, and transportation.

These tubes provide solutions for different applications because of their important features. Some of the features include;

• Corrosion resistance: HDPE does not react with chemicals or moisture. This prevents the tubes from corroding or rusting. The tubes are used for transferring liquids in construction and agricultural without being contaminated.
• Lightweight and flexible: HDPE tubes are light and flexible. This makes the tubes easy to handle and install. For example, the electrical and telecommunications industries use these tubes as conduits for cables. Their flexibility allows them to bend around corners without breaking.
• Duvet construction: These tubes are strong and durable. They can resist impact, abrasion, and harsh weather conditions. This feature makes them suitable for underground applications in the construction and water industries. They ensure a long-lasting and reliable pipeline system.
• High-density polyethylene (HDPE) material: These tubes are made from HDPE material, which is a thermoplastic polymer. It is formed from the monomer ethylene. The polyethylene has a density of 0.941 to 0.965 g/cm3. This makes the material more crystalline, which provides the tubes with increased strength and rigidity. These tubes are used for different applications that require strength, such as; pressure pipes, containers, and plastic bags.
• Versatility: These tubes are used in different applications in different industries. This is because of their outstanding features. They are resistant to UV rays, chemicals, and moisture. The tubes are used in agricultural for irrigation systems, in construction for drainage systems, and in the industrial sector for transporting gases and liquids. Their versatility makes them more preferable than other tubes.
• Recyclability: These tubes can be recycled. The recycling process involves collecting the used HDPE tubes, cleaning them, and then melting them to form pellets. The pellets can be used to manufacture new HDPE products. Recycling these tubes conserves energy and reduces the amount of plastic waste in the environment.

Scenarios of HDPE Tube

HDPE tubes are widely applicable across various industries because of their durability, lightweight nature, and versatility. Below are some common application scenarios.

• Construction Industry

  HDPE pipes are used in the construction industry, especially in civil works. They are used as culverts in the construction of highways and roads. They direct water under the roads, highways, and railway lines, helping to eliminate water buildup and reduce flooding.

  HDPE pipes are also used in the construction of bridges. They are used in drainage applications, helping to transport stormwater and rainwater efficiently.

  These tubes are also used in the construction of utilities trenches. Their non-corrosive nature ensures long-term water and sewage transportation.

• Manufacturing

  The manufacturing industry uses an HDPE plastic tube to manufacture different products, including containers, toys, and household items. The HDPE plastic is molded into different shapes and products through extrusion or injection molding.

• Agriculture

  HDPE tubes are used for irrigation in farms and agricultural lands. They are used in drip and sprinkler irrigation systems, helping to deliver water to crops efficiently and reducing water wastage.

  They are also used for carrying fertilizers to crops and clean water to livestock. Their lightweight nature makes them easy to handle and transport in farms.

• Telecommunication and Electrical Industry

  HDPE tubes are commonly used in telecommunications and electrical industries for cable management. The smooth interior surface of these tubes reduces friction, making it easy to pull wires and cables during installation. The durability and strength of the tubes protect the cables from impact and environmental hazards.

  HDPE pipes are used for transporting oil and gas products over long distances. They are used in offshore and onshore pipelines because of their corrosion-resistant properties, ensuring the safe transportation of hydrocarbons.

  They are also used in the transfer of liquids from tankers to storage facilities and in the transportation of liquefied natural gas (LNG).

• Electrical Conduits

  HDPE tubes are used in electrical conduits for protecting and routing electrical wires and cables. Their lightweight nature makes them easy to install in both above-ground and underground applications.

How to choose hdpe tube

When choosing an hdpe tube, several factors must be considered to ensure the right product is selected for the intended application. These factors include:

• Consider the Application Requirements

  The first thing to consider is the application requirements. This involves looking at the environmental conditions where the tube will be used. It is important to check the temperature and whether it will be used in a pressurized application. Also, look at the fluid or material being transported to determine if it has any corrosive properties. The application requirements help to determine the right tube material and specifications.

• Check the Tube Material

  HDPE is the most popular material for making tubes and is chosen for its durability and strength. The material is known for its resistance to impact and ability to withstand harsh environmental conditions. HDPE is also flexible and lightweight, making it easy to handle during installation. Other materials like PVC and polypropylene may also be used to make tubes. These materials have different properties and are suitable for specific applications.

• Consider the Tube Size and Diameter

  The size of the tube will greatly affect its performance in different applications. Larger diameter pipes are used for heavy-duty applications like sewer systems and drainage. In contrast, smaller diameter pipes are suitable for lightweight applications like electrical conduit. The size and diameter of the tube also relate to its wall thickness. A thicker wall provides extra strength, while a thinner wall makes the tube more lightweight and easy to use.

• Check the SDR and Pressure Rating of the Tube

  The standard dimension ratio (SDR) is a measure of the HDPE tube's geometry. It is the ratio between the diameter and the wall thickness of the tube. Tubes with lower SDR values have thicker walls and higher pressure ratings. The pressure rating indicates the maximum internal pressure the tube can withstand. Choosing a tube with the right SDR and pressure rating is important to ensure it meets the application's hydraulic requirements.

• Evaluate the Cost and Availability

  Once all the technical aspects of the HDPE tube are looked at, it is also important to consider its cost and availability. Different suppliers will have different prices for their products depending on the quality and specifications. It is important to choose a tube that is within budget. Also, consider the lead time required to get the HDPE tube on site. This will depend on the tube's availability and the supplier's location.
