The Double Layer Axial Hollow Pipe, also known as the double layer axial direction hollow wall pipe, is a groundbreaking piping solution engineered with dual layers of material separated by a hollow space. This avant-garde design enhances strength and durability while preserving a lightweight and flexible structure. The internal hollow space facilitates efficient transport of fluids or gases, rendering it ideal for a myriad of applications including drainage, sewage systems, and cable protection. Additionally, the double layer configuration imparts superior resistance to pressure, impacts, and environmental factors, ensuring exceptional long-term performance and reliability.
Advantages:
The hollow wall pipe, with its optimized structure, provides substantial raw material savings compared to the solid wall pipe while delivering the same ring stiffness. This product is lightweight, easy to connect, and significantly reduces project costs.
The connection method for Double Layer Axial Hollow Pipes involves expertly joining sections using fittings or couplings designed for this specific system. These fittings ensure a secure and watertight seal, facilitating efficient fluid or gas transfer. Common methods include solvent cement welding, mechanical couplings, and compression fittings, tailored to application requirements and pipe material. Some manufacturers also offer proprietary connection systems specifically for their double layer axial hollow pipe products, further enhancing reliability and performance.
PVC-U is the predominant type of PVC used for pipes and fittings, ideal for transporting drinking water, soil and waste, sewage, underground drainage, and various industrial applications.
Pipes and fittings made of PVC-U offer numerous advantages. They ensure safe drinking water transportation, are lightweight, easy to handle, and cost-effective. Their technical properties include high mechanical performance, long-lasting durability (over 100 years for underground pipes), excellent chemical resistance, and UV resistance. Additionally, PVC-U pipes are environmentally friendly and fully recyclable.
