Product Description

The Double Layer Axial Hollow Pipe, also referred to as double layer axial direction hollow wall pipe, is an innovative piping solution featuring two layers of material with a hollow space in between. This design provides enhanced strength and durability while maintaining a lightweight and flexible construction. The hollow space within the pipe allows for efficient transport of fluids or gases, making it suitable for various applications such as drainage, sewage systems, and cable protection. The double layer design also offers improved resistance to pressure, impact, and environmental factors, ensuring long-term performance and reliability.
The advantsges:
In the case of the same ring stiffness,the hollow wall pipe with optimized structure can save much more raw materials than the slid wall pipe.The product is light in weight,convenient in connection and low in project cost.

Connection Method

 

The connection method for Double Layer Axial Hollow Pipes typically involves joining the sections of pipe using compatible fittings or couplings specifically designed for this type of piping system. These fittings are often designed to provide a secure and watertight seal between pipe sections, ensuring efficient fluid or gas transfer. Common connection methods include solvent cement welding, mechanical couplings, or compression fittings, depending on the specific requirements of the application and the pipe material. Additionally, some manufacturers may offer proprietary connection systems tailored to their double layer axial hollow pipe products.
    

Product Advantages

PVC-U is the most common PVC type for pipes and fittings including transportation of drinking water, soil and waste, sewage and underground drainage and industrial applications.

Pipes and fittings made of PVC-U have many benefits. They are a safe choice for transportation of drinking water, light and easy to handle and affordable. Technical properties include high mechanical performance, high durability (at least 100 years for underground pipes), high chemical resistance and resistance to UV exposure. Moreover, PVC-U pipes have favorable environmental profiles and are 100% recyclable.
1.Double-Layer Structure: The pipe consists of two layers - an inner layer and an outer layer - with a hollow space between them, enhancing its structural integrity and durability.
2. Axial Hollow Wall: The axial hollow wall design reduces the overall weight of the pipe while maintaining its strength, making it easier to handle and install.
3. High Strength: Despite its lightweight design, the pipe offers high strength and resistance to external loads, ensuring long-term reliability in underground applications.
4. Corrosion Resistance: Made from high-quality PVC materials, the pipe is resistant to corrosion, rust, and chemical degradation, prolonging its service life even in harsh underground environments.
5. Easy Installation: The lightweight construction and smooth interior surface of the pipe facilitate easy handling, transportation, and installation, reducing labor and installation costs.
6. Versatile Applications: The pipe is suitable for various applications, including stormwater drainage, sewer systems, culverts, and underground utilities, providing versatile solutions for infrastructure projects.
