Introducing the Double Layer Axial Hollow Pipe, a revolutionary piping solution designed to elevate your infrastructure projects. Also known as the double layer axial direction hollow wall pipe, this advanced piping system features a dual-layer construction with a strategically designed hollow space in between. This innovative design not only amplifies strength and durability but also ensures a lightweight and highly flexible structure. The hollow space within the pipe facilitates the efficient transport of fluids and gases, making it an ideal choice for diverse applications such as drainage, sewage systems, and cable protection. The double-layer architecture enhances resistance to pressure, impact, and environmental challenges, guaranteeing robust long-term performance and unparalleled reliability.
The Advantages:
When comparing pipes with identical ring stiffness, the hollow wall pipe's optimized structure allows for significant raw material savings compared to solid wall pipes. This product is exceptionally lightweight, ensuring ease of connection and drastically reducing project costs, making it a highly economical and practical solution for modern infrastructure needs.
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 specialized fittings ensure a secure, watertight seal between pipe sections, optimizing the efficient transfer of fluids or gases. Connection methods commonly utilized include solvent cement welding, mechanical couplings, or compression fittings, tailored to the specific requirements of the application and pipe material. Additionally, some manufacturers provide proprietary connection systems uniquely designed for their double layer axial hollow pipe products.
PVC-U is the predominant PVC type utilized for pipes and fittings. It is extensively used for the transportation of drinking water, soil and waste management, sewage, underground drainage, and various industrial applications.
PVC-U pipes and fittings offer numerous advantages. They are a dependable choice for transporting drinking water, lightweight, easy to handle, and cost-effective. Their technical properties include exceptional mechanical performance, high durability (lasting over 100 years for underground pipes), strong chemical resistance, and UV exposure resilience. Furthermore, PVC-U pipes boast favorable environmental profiles and are entirely recyclable.
