Introducing the Double Layer Axial Hollow Pipe, an avant-garde piping solution, also known as the double layer axial direction hollow wall pipe. This pipe is engineered with a dual-layer structure separated by a hollow space, culminating in superior strength and unmatched durability. Despite its robust build, it boasts a lightweight and flexible form. The internal hollow space is ingeniously designed for the efficient transport of fluids or gases, making it a versatile choice for a myriad of applications including drainage, sewage systems, and cable protection. With its double-layer construction, it offers exceptional resistance to pressure, impact, and adverse environmental conditions, guaranteeing long-term performance and unwavering reliability.
Advantages:
The hollow wall pipe, with its optimized structure, provides the same ring stiffness as solid wall pipes but remarkably reduces the amount of raw materials needed. This innovation ensures the product remains lightweight, facilitating easier connections and significantly lowering overall project costs.
The connection method for Double Layer Axial Hollow Pipes involves joining sections using specifically designed fittings or couplings. These ensure a secure and watertight seal for efficient fluid or gas transfer. Common methods include solvent cement welding, mechanical couplings, or compression fittings, tailored to the pipe material and application needs. Some manufacturers also offer proprietary connection systems for enhanced compatibility.
PVC-U is the most commonly used type of PVC for pipes and fittings. It's ideal for transporting drinking water, soil and waste, sewage, underground drainage, and various industrial applications.
Pipes and fittings made from PVC-U come with numerous advantages. They are safe for drinking water transport, light, easy to handle, and cost-effective. Technically, they offer high mechanical performance, exceptional durability (lasting over 100 years underground), high chemical resistance, and UV resistance. Additionally, PVC-U pipes have an excellent environmental profile, being 100% recyclable.
