The Double Layer Axial Hollow Pipe, also referred to as the double layer axial direction hollow wall pipe, is a groundbreaking piping solution that integrates two layers of robust material with an intervening hollow space. This innovative design significantly enhances strength and durability while maintaining remarkable lightweight and flexibility. The hollow chamber within the pipe ensures efficient transport of fluids or gases, making it ideal for a myriad of applications such as drainage systems, sewage management, and cable protection. Furthermore, the double layer structure provides superior resistance to pressure, impact, and various environmental factors, guaranteeing long-term efficiency and reliability.
Advantages:
Compared to solid wall pipes with the same ring stiffness, our hollow wall pipe with an optimized structure can significantly reduce raw material usage. This product is exceptionally lightweight, making it easier to handle and connect, thereby reducing overall 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 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, tailored to meet the specific requirements of the application and the pipe material. Additionally, some manufacturers may offer proprietary connection systems uniquely designed for their double layer axial hollow pipe products.
PVC-U is the most prevalent type of PVC for pipes and fittings, commonly used in the transportation of drinking water, soil and waste, sewage and underground drainage, and various industrial applications.
Pipes and fittings made from PVC-U offer numerous advantages. They are the safest choice for the transportation of drinking water, being lightweight, easy to handle, and cost-effective. Their technical properties include high mechanical performance, exceptional durability (lasting at least 100 years for underground pipes), high chemical resistance, and UV exposure resistance. Moreover, PVC-U pipes boast favorable environmental profiles and are 100% recyclable, making them an eco-friendly option.
