Understanding Corrugated High-Density Polyethylene Pipe: A Closer Look at LESSO’s HDPE Double-Wall Corrugated Pipe and Fittings

by Diana Uncategorized

When it comes to durable and long-lasting piping solutions, HDPE (High-Density Polyethylene) double-wall corrugated pipes have emerged as one of the most trusted options. Known for their superior strength, flexibility, and longevity, these pipes are widely used in applications such as drainage systems, stormwater management, sewage systems, and more. In this blog, we will explore what makes corrugated high density polyethylene pipe a reliable solution, how to understand their standards, and why LESSO‘s HDPE Double-Wall Corrugated Pipe and Fittings comply with international norms and exceed expectations for performance and durability.

What Is Corrugated High-Density Polyethylene (HDPE) Pipe?

Corrugated HDPE pipes are designed with a double-wall structure that combines a smooth inner wall and a rigid, corrugated outer wall. The inner surface facilitates efficient water flow with minimal friction, while the corrugated outer layer offers structural strength and resistance to crushing under external loads. This combination makes these pipes suitable for a wide range of underground and above-ground applications.

The HDPE material offers resistance to corrosion, chemicals, and abrasion, making it ideal for systems that need to withstand harsh conditions over the long term.

Understanding the Standards of HDPE Double-Wall Corrugated Pipe

One of the key factors in ensuring the performance and reliability of HDPE double-wall corrugated pipes is adherence to recognized industry standards. Standards not only ensure the pipes meet safety and performance requirements but also guarantee compatibility with other components in the piping system.

LESSO’s HDPE Double-Wall Corrugated Pipe and Fittings are designed to meet various international standards, ensuring they perform optimally in demanding environments.

Let’s break down the relevant standards for LESSO’s HDPE pipes:

1. BS EN 13476-2:2007

The BS EN 13476-2:2007 standard specifies the requirements for the performance and dimensions of plastic piping systems used for the transportation of water, wastewater, and other fluids. Specifically, this standard is concerned with the double-wall corrugated pipes made from polyethylene (PE) and their suitability for underground use.

This standard ensures that the pipes meet the following criteria:

– Ring stiffness: The pipes must meet specific performance requirements for ring stiffness, ensuring they can withstand external loads without deformation or collapse. This is crucial for applications in areas where the pipes are subject to heavy traffic or soil pressure.

– Durability: The pipes must have resistance to abrasion, chemicals, and corrosion to ensure they last for decades with minimal maintenance.

– Compatibility: The pipes should be compatible with other components, such as fittings, joints, and manholes, used in the same drainage or water supply system.

By meeting the BS EN 13476-2 standard, LESSO’s HDPE double-wall corrugated pipes ensure that they offer high performance and reliability in demanding environmental conditions.

2. BS EN 13476-3:2007 + Al:2009

This part of the standard, BS EN 13476-3:2007, deals specifically with the fittings and jointing methods for HDPE piping systems. The inclusion of the +Al:2009 indicates an updated revision that also includes aluminum-reinforced pipe options, which are sometimes used for increased durability or specific use cases.

For LESSO’s HDPE Double-Wall Corrugated Pipes and fittings, adherence to this standard means:

– Joint integrity: The fittings must be designed to ensure secure, leak-proof connections between pipes, which are crucial for maintaining the efficiency and safety of the entire piping system.

– Performance of fittings: The fittings should not only match the pipe specifications in terms of stiffness and resistance but also ensure compatibility with different installation methods, including electrofusion and butt fusion welding, which are commonly used for HDPE systems.

– Ease of installation: The standard ensures that the fittings can be easily integrated into the pipeline, even in complex or space-constrained installations.

With LESSO’s HDPE fittings, you can rest assured that the jointing methods and fitting quality adhere to these rigorous standards for long-term, trouble-free performance.

3. GB/T 19472-1

The GB/T 19472-1 standard is the Chinese national standard for plastic pipes and fittings for drainage and sewer systems, focusing on HDPE pipes. This standard specifies the material properties, dimensions, and performance characteristics of HDPE double-wall corrugated pipes used in drainage and sewage applications.

For LESSO, meeting the GB/T 19472-1 standard ensures:

– High resistance to corrosion: The pipes and fittings are engineered to handle various environmental stresses, including exposure to chemicals and high moisture conditions.

– Durability in harsh conditions: The pipes are designed to maintain their structural integrity even under heavy traffic loads, deep burial, or high-pressure environments.

– Environmental protection: The pipes are environmentally friendly, being fully recyclable, and contributing to sustainable construction practices.

By following the GB/T 19472-1 standard, LESSO’s HDPE double-wall corrugated pipes ensure that they meet the regulatory and performance requirements for drainage systems in China and other regions with similar standards.
