Discover the Double Layer Axial Hollow Pipe, a state-of-the-art piping solution also known as the double layer axial direction hollow wall pipe. This cutting-edge product features a dual-layer construction with a hollow space in between, delivering superior strength and durability while remaining lightweight and flexible. The innovative hollow core ensures efficient fluid and gas transport, making it ideal for diverse applications including drainage, sewage systems, and cable protection. Furthermore, the dual-layer design enhances resistance to pressure, impact, and environmental conditions, guaranteeing exceptional long-term performance and reliability.
Key Advantages:
Compared to solid wall pipes, the hollow wall pipe with its optimized structure delivers the same ring stiffness while significantly reducing raw material usage. Its lightweight nature makes handling and installation a breeze, leading to lower project costs overall. The product's design not only ensures easy connection but also offers substantial economic benefits for large-scale projects.
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 meticulously crafted to ensure a secure and watertight seal between pipe sections, guaranteeing efficient fluid or gas transfer. Common connection methods include solvent cement welding, mechanical couplings, or compression fittings, tailored to the specific requirements of the application and the pipe material. Additionally, some manufacturers offer proprietary connection systems, specially engineered for their double layer axial hollow pipe products, enhancing ease of installation and reliability.
PVC-U is the most common PVC type for pipes and fittings, widely used in the transportation of drinking water, soil and waste, sewage, underground drainage, and various industrial applications.
Pipes and fittings made of PVC-U offer numerous benefits. They are a safe choice for transporting drinking water, being light and easy to handle, and remarkably affordable. Their technical properties include superior mechanical performance, exceptional durability (lasting at least 100 years for underground pipes), high chemical resistance, and resistance to UV exposure. Additionally, PVC-U pipes boast favorable environmental profiles and are 100% recyclable, making them a sustainable choice for modern infrastructure.
1.
Double-Layer Structure : The pipe consists of two robust layers - an inner layer and an outer layer - with a hollow space in between, significantly enhancing its structural integrity and durability.
2. Axial Hollow Wall : The axial hollow wall design significantly reduces the overall weight of the pipe while maintaining its strength, facilitating easier handling and installation.
3. High Strength: Despite its lightweight design, the pipe offers remarkable strength and resistance to external loads, ensuring long-term reliability in demanding underground applications.
4. Corrosion Resistance : Crafted from high-quality PVC materials, the pipe exhibits exceptional resistance to corrosion, rust, and chemical degradation, thereby prolonging its service life even in the harshest underground environments.
5. Easy Installation : The lightweight construction and smooth interior surface of the pipe make handling, transportation, and installation effortless, effectively reducing labor and installation costs.
6. Versatile Applications : The pipe is highly suitable for a myriad of applications, including stormwater drainage, sewer systems, culverts, and underground utilities, offering versatile and reliable solutions for infrastructure projects.
