As a professional manufacturer with over a decade of experience in plastic pipe production, Qingdao Yongke Machinery Co., Ltd. proudly presents our High-Speed HDPE Hollow Wall Winding Spiral Pipe Line, engineered specifically for efficient water storage tank systems. Operating from our 10,000-30,000 square meter facility with ISO 9001, ISO 14000, and OHSAS 18001 certified processes, we have developed this product line to address the critical need for reliable, durable, and high-capacity drainage and overflow solutions in water containment applications worldwide. Our pipe is manufactured using advanced winding technology that creates a unique structural profile, offering superior hydraulic performance and long-term reliability for tank operators, municipal water projects, and industrial storage facilities.
Core Product Features & Technical Advantages:
- Advanced Hollow Wall Spiral Structure: The distinctive manufacturing process winds HDPE strips into a continuous, seamless spiral profile with hollow chambers in the wall. This design creates an optimal balance between material usage, structural rigidity, and weight, resulting in a pipe that is both strong and lightweight for easier handling and installation.
- Superior Hydraulic Capacity: The smooth interior surface, combined with the consistent spiral geometry, minimizes friction loss (Manning's 'n' value as low as 0.009), allowing for higher flow velocities and greater discharge capacity compared to traditional corrugated or solid-wall pipes of equivalent diameter. This is crucial for rapid drainage during overflow events or scheduled tank maintenance.
- Exceptional Chemical & Corrosion Resistance: Manufactured from premium-grade, virgin High-Density Polyethylene resin, the pipe is inherently resistant to a wide range of chemicals found in water treatment, including mild acids, alkalis, and salts. It will not rust, corrode, or support biological growth on its interior, ensuring consistent performance and water quality over decades of service.
- High Ring Stiffness & Load-Bearing Capacity: The hollow-wall spiral design provides excellent ring stiffness (typically SN8, SN12.5, or higher upon request), enabling it to withstand significant external soil loads and internal pressures when buried or used in exposed applications around storage tanks. This structural integrity prevents deformation and maintains the designed flow area.
-
Leak-Free Jointing Systems: We offer compatible jointing solutions to ensure a sealed pipeline system. Options include:
- Spigot and Socket with EPDM Gasket: Allows for fast, reliable, and flexible assembly, accommodating minor ground movement.
- Butt Fusion Welding: Creates a monolithic, permanent, and fully pressure-tight joint with strength equal to the pipe itself, ideal for critical pressure applications.
- Long Service Life & Low Maintenance: HDPE material is UV-stabilized for above-ground use and maintains its flexibility and strength in a wide temperature range (-40°C to +60°C). The non-degrading nature of HDPE and the joint integrity translate to a service life exceeding 50 years with virtually no maintenance required, offering a superior life-cycle cost.
- Customization & Versatility: Beyond standard sizes, we can tailor the pipe's diameter, wall thickness, length, and color to meet specific project requirements. It is suitable for various roles in tank systems, including primary overflow pipes, scour pipes, drain pipes, and vent pipes.

Benefits for Your Water Storage Project:
- Enhanced System Safety: Provides a reliable and high-capacity path for overflow, preventing tank overtopping and potential structural damage during heavy inflow events.
- Reduced Installation Time & Cost: The lightweight nature and availability of mechanical joint options significantly reduce the need for heavy lifting equipment and skilled welders on-site, accelerating project timelines.
- Future-Proof Infrastructure: The durability and chemical resistance ensure the drainage system remains functional and intact for the entire lifespan of the water storage tank, avoiding costly replacements or repairs.
- Environmental Sustainability: HDPE is a recyclable material. The smooth bore and leak-free joints prevent water loss and soil contamination, supporting responsible water management practices.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of the hollow wall winding design compared to solid-wall HDPE pipe?
A1: The hollow wall spiral structure provides an excellent strength-to-weight ratio. It offers high ring stiffness to resist external loads while using less material than a solid wall, making it more cost-effective and easier to handle and install for large diameters commonly used in tank drainage.
Q2: Can this pipe be used for pressurized applications within a tank system, like a scour line?
A2: Yes, absolutely. While often used for gravity flow (overflow/drainage), these pipes are manufactured to specific pressure ratings (e.g., PN6, PN10). When specified for pressure service and joined using butt fusion, they form a fully pressure-tight system suitable for scour lines or other pressurized connections.
Q3: How does the installation process work, and what kind of foundation is required?
A3: Installation is straightforward. For buried applications, a properly prepared and compacted bedding (usually granular material) is required according to the project's geotechnical specifications. The pipes are then laid and joined using the gasketed spigot-socket method for speed or butt fusion for permanence. Our technical data sheets provide detailed installation guidelines.
Q4: Is the pipe resistant to sunlight (UV) if installed above ground near the tank?
A4: Yes, our standard HDPE compound includes carbon black or other UV stabilizers that provide protection against degradation from sunlight exposure, making it suitable for above-ground installations. For very long-term, fully exposed applications, additional protective wrapping or painting can be discussed.
Q5: What are the available diameter ranges, and can you produce non-standard sizes?
A5: Our standard production range typically spans from DN200 mm to DN3000 mm. We maintain tooling for many common sizes. For projects requiring diameters or wall thicknesses outside our standard catalog, we offer customization services. Please provide your detailed requirements for evaluation.
Q6: Do you supply all necessary fittings and accessories for a complete system?
A6: Yes, as a manufacturer, we can provide a full system package. This includes bends (elbows), reducers, tees, manholes, end caps, and adaptors to other pipe materials (like ductile iron or PVC). We ensure all components are compatible and designed to work seamlessly together.
Q7: What is the lead time for an order, and what is your packaging for export?
A7: Lead time depends on order quantity and specifications. Standard items may be available from stock, while custom orders typically require 20-30 days for production. For export, pipes are securely bundled and packed on wooden crates or pallets suitable for ocean freight, ensuring they arrive at your site in perfect condition.
Q8: How does your quality control process ensure product consistency?
A8> Our manufacturing is governed by an ISO 9001 certified quality management system. This involves rigorous raw material inspection, in-process monitoring of winding parameters, wall thickness, and diameter, and final testing including dimensional checks, stiffness tests, and visual inspection. Batch test reports can be provided upon request.
