HDPE Tube Manufacturers

HDPE tubes are pipes made from high-density polyethylene (HDPE) granule material. HDPE is a thermoplastic polymer known for its strong and durable properties. HDPE tubes are commonly used in various applications such as water supply, irrigation, gas distribution, and industrial processes.
HDPE tubes offer several advantages over other types of pipes. They have high resistance to corrosion, chemicals, and UV rays, making them suitable for outdoor and underground installations. HDPE tubes are lightweight and flexible, making them easy to handle and install. They also have a smooth inner surface that reduces friction and minimizes pressure losses.
HDPE PIPE & HDPE PIPE FITTING

  • Long service life

    The PE pipe has high molecular weight, good stability and anti-aging ability. Under normal operating temperature, the service life of PE pipe can be guaranteed to be more than 50 years.

  • Environmental performance

    PE pipes do not add metal stabilizers during the processing process, and the material is non-toxic, without scaling layer, and does not breed bacteria. It is a safe and hygienic pipeline material. PE material itself can be recycled and will not produce substances that have an impact on the environment.

  • Corrosion resistance

    The molecular structure stability of PE pipes is extremely high and there is no electrochemical corrosion. Among many pipeline materials, the corrosion index of PE pipes is relatively small, and apart from a few oxidants, they can withstand corrosion from various chemical media.

  • Impact resistance

    PE pipe is a high toughness pipe material with a fracture elongation rate of over 500%, which has impact and earthquake resistance, and strong adaptability to uneven settlement of the pipe foundation.

  • Low temperature resistance

    HDPE pipes have good low-temperature resistance and will not exhibit brittle cracking even in extremely low environments.

  • Wear resistance

    HDPE pipes have flat walls and low flow resistance, resulting in fluid friction performance, not only wear resistance but also high conveying efficiency.

HDPE Tube

Basic Characteristics of HDPE Tubes

Material Introduction

HDPE (High-Density Polyethylene) is a highly crystalline thermoplastic polymer. It is polymerized from ethylene monomers and has a linear molecular structure. This structure gives HDPE its high crystallinity and density (typically 0.93 g/cm³ to 0.97 g/cm³). The high crystallinity of HDPE results in superior physical properties, particularly in terms of wear resistance, tensile strength, and compressive strength.

  • Molecular Structure: HDPE molecules have a relatively simple chain structure with few branches, resulting in higher mechanical strength.
  • Applications: HDPE is widely used in the production of various pipes, containers, bottles, and other products, especially in environments requiring high strength and chemical resistance.

Advantages

  • Corrosion Resistance: HDPE tubes effectively resist corrosion from most chemical substances. They exhibit good resistance to common chemical solvents, acids, bases, and salts. HDPE tubes are a preferred material in petrochemicals, agricultural irrigation, and wastewater treatment. 
  • Example: In agricultural irrigation systems, HDPE tubes resist corrosion from fertilizers and pesticide solutions, significantly extending their service life.
  • UV Resistance: HDPE itself has some resistance to UV radiation, but prolonged exposure to sunlight can lead to material degradation. Therefore, HDPE tubes are usually treated with UV stabilizers. 
  • UV Stability: By adding UV stabilizers (such as carbon black) during the manufacturing process, the UV resistance of HDPE tubes can be enhanced, making them suitable for outdoor piping systems (such as urban water supply and drainage pipes).
  • High Strength: HDPE tubes have high tensile and compressive strength, allowing them to be used under high pressure without easily cracking or deforming. 
  • Compressive Strength: For example, a DN100 (100mm outer diameter) HDPE tube typically has a compressive strength of 10-16 MPa, suitable for high-pressure environments.
  • High and Low Temperature Resistance: HDPE tubes can withstand temperatures ranging from -40°C to +60°C, but they become brittle at extremely low temperatures (below -50°C). The temperature resistance range of different HDPE tube products can be modified as needed; for example, low-temperature resistant and anti-brittle HDPE tubes can withstand even lower temperatures.
  • Lightweight: Compared to traditional pipes such as steel and cast iron pipes, HDPE tubes are lightweight and easy to install. Due to their lightweight nature, they can effectively reduce transportation costs and improve construction efficiency. Installation can be completed manually or with small machinery, without the need for large heavy equipment.

Disadvantages

  • Easy to Scratch: The surface of HDPE tubes is relatively soft and easily scratched by sharp objects, especially during installation and transportation. Scratches may affect their sealing performance, leading to water leakage or other leaks. 
  • Solutions: Protective measures should be taken during transportation and storage, such as using scratch-resistant packaging materials. In addition, some HDPE tube products with reinforced surfaces (such as wear-resistant HDPE tubes) can better resist this problem.
  • Low-Temperature Brittleness: Although HDPE tubes have strong low-temperature resistance, they may become brittle and fracture in extremely low-temperature environments. This requires special attention when used in cold northern regions. 
  • Modification: To address this issue, some HDPE tubes use modified materials (such as reinforced polymers or added low-temperature resistant agents) to improve their low-temperature toughness.
  • Susceptible to Environmental Stress Cracking: HDPE tubes that are subjected to long-term stress or are at high stress concentration points may experience environmental stress cracking (ESC). This is especially true if there are defects or improper handling of the pipe surface, which can accelerate crack formation. 
  • Preventive Measures:  Selecting appropriate pipe wall thickness, avoiding high stress concentrations, and conducting regular pipe inspections are recommended.

Physical Properties of HDPE Tubes

Mechanical Properties

  • Tensile Strength: The tensile strength of HDPE is typically between 25-40 MPa. For some high-grade HDPE (such as PE100), the tensile strength can reach over 40 MPa. Tensile strength determines the pipe's ability to deform under external force and is an important indicator of whether the pipe can withstand high loads.
  • Flexural Strength: HDPE tubes have high flexural strength and are usually suitable for applications requiring a certain degree of bending (such as pipes that need to bypass obstacles). HDPE tubes are not easily broken or deformed during bending.
  • Impact Resistance: HDPE tubes have excellent impact resistance. Even in low-temperature environments, HDPE tubes can maintain strong impact resistance,

making them stable and reliable even in harsh construction environments.

Thermal Properties

  • High Temperature Resistance: The high-temperature resistance of HDPE is generally below 80°C.  Long-term exposure to high-temperature environments will cause HDPE tubes to soften and deform, making them unsuitable for transporting high-temperature fluids.
  • Linear Expansion Coefficient: Due to the high linear expansion coefficient of HDPE tubes, significant temperature changes may cause changes in the pipe length. The impact of temperature changes on the pipe needs to be considered during design.

Chemical Properties

  • Chemical Corrosion Resistance: HDPE exhibits extremely strong resistance to most common chemical substances (such as acids, bases, and salt solutions), making it particularly suitable for chemical plants and wastewater treatment systems.
  • Water Resistance: HDPE is almost non-absorbent and can resist the erosion of most water-soluble substances, therefore it is widely used in water supply pipes, irrigation pipes, etc.

Electrical Properties

  • Electrical Insulation: Due to the excellent electrical insulation properties of HDPE, HDPE tubes are often used for cable protection and conduit in power facilities.
