HDPE (High-Density Polyethylene) double-wall corrugated pipes are widely used for various applications, including drainage systems, sewage systems, cable protection, and underground conduits. Here are some general specifications for HDPE double-wall corrugated pipes:

Material: High-Density Polyethylene (HDPE)

HDPE is a thermoplastic polymer known for its high strength, durability, and resistance to chemicals, corrosion, and abrasion.

Size Range:

Outer Diameter (OD): Typically available in various sizes ranging from 75 mm (3 inches) to 1200 mm (48 inches) or more, depending on the manufacturer.

Inner Diameter (ID): The inner diameter is smaller than the outer diameter and can vary depending on the manufacturer and specific application.

Wall Structure:

Double Wall Corrugated: The pipe consists of two layers—a smooth inner layer and a corrugated outer layer. The corrugated design provides structural strength while maintaining flexibility.

Pipe Stiffness:

HDPE double-wall corrugated pipes have different stiffness classes that define their load-bearing capacity and flexibility. Common classes include SN2, SN4, SN8, SN12.5, and SN16, among others. The class designation corresponds to the pipe's ring stiffness, with higher numbers indicating higher stiffness.

Length:

Standard lengths are usually 6 meters (20 feet) or 12 meters (40 feet). Custom lengths may also be available depending on the manufacturer and project requirements.

Coupling System:

HDPE double-wall corrugated pipes are typically joined using a coupling system that provides a secure and leak-proof connection. Common coupling methods include push-fit (socket and spigot), fusion welding, or mechanical couplings.

Standards and Approvals:

HDPE double-wall corrugated pipes should comply with relevant industry standards and certifications, such as:

ASTM F2648: Standard Specification for 2 to 60 inch [50 to 1500 mm] Annular Corrugated Profile Wall Polyethylene (PE) Pipe and Fittings for Land Drainage Applications.

EN 13476-3: Plastics piping systems for non-pressure underground drainage and sewerage - Part 3: Specifications for pipes and fittings with smooth internal and external surface and structured-wall pipes of the unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) - Amendment 1: Structured-wall pipes of PE.

Additional Features:

Some HDPE double-wall corrugated pipes may have additional features, such as built-in socket ends, pre-installed pull tapes for cable installation, or special coatings for enhanced chemical resistance or UV protection. These features can vary depending on the manufacturer and specific product line.

It's important to note that specific specifications and product details may vary among manufacturers. Therefore, it is recommended to consult the manufacturer's product documentation or contact them directly to obtain precise and up-to-date information for your specific project requirements.
