The Double Layer Axial Hollow Pipe, also known as the double layer axial direction hollow wall pipe, is a groundbreaking piping innovation that features a dual-layer construction with a hollow space sandwiched in between. This advanced design offers unparalleled strength and durability while remaining lightweight and flexible. The hollow cavity within the pipe ensures the efficient transport of fluids or gases, making it ideal for applications in drainage, sewage systems, and cable protection. Additionally, the double-layer construction significantly enhances resistance to pressure, impact, and various environmental factors, ensuring long-lasting performance and reliability.
The Advantages:
When compared to solid wall pipes, the hollow wall pipe with an optimized structure saves substantially more raw materials while delivering the same level of ring stiffness. This product is not only lightweight and easy to connect, but it also offers significant reductions in project costs.
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 an impeccable, watertight seal between pipe sections, thus guaranteeing efficient fluid or gas transfer. Popular connection techniques include solvent cement welding, mechanical couplings, or compression fittings, all chosen based on the specific requirements of the application and the pipe material. Additionally, some manufacturers may offer proprietary connection systems uniquely tailored to their double layer axial hollow pipe products.
PVC-U is the most prevalent type of PVC for pipes and fittings, widely used for transporting drinking water, soil and waste, sewage, underground drainage, and various industrial applications.
Pipes and fittings made from PVC-U offer numerous advantages. They are a secure option for transporting drinking water, lightweight and easy to handle, and cost-effective. Their technical properties include exceptional mechanical performance, remarkable durability (lasting at least 100 years for underground pipes), high chemical resistance, and robustness against UV exposure. Moreover, PVC-U pipes boast favorable environmental profiles and are 100% recyclable, making them an eco-friendly choice.
