Corrugated plastic pipes are used for plumbing, drainage, and stormwater management. They are made from high-density polyethylene (HDPE) and offer exceptional hydraulics and strength. These pipes are available in a range of diameters, typically from 3 inches to 60 inches, depending on whether they are single or double-walled. Single-wall pipes range from 3 inches to 24 inches in diameter, while double-wall pipes can be as small as 4 inches and as large as 60 inches. The larger diameters, ranging from 12 inches to 60 inches, are often used for gravity-flow storm sewer and subsurface drainage applications.

Corrugated plastic pipe diameters vary, from 3-4 nominal inside pipe diameter
Corrugated plastic pipe diameters vary, typically ranging from 3 to 24 inches for single-wall pipes and 4 to 60 inches for double-wall pipes. The Pacific Corrugated Pipe Company, for instance, offers single-wall pipes in diameters from 3 to 24 inches and double-wall pipes in diameters ranging from 4 to 60 inches (integral bell and spigot style) or 8 to 36 inches (plain end).
The diameter of corrugated plastic pipes is an important consideration when selecting the appropriate pipe for a specific application. The pipe diameter determines the flow capacity and affects the overall performance of the drainage or piping system.
For smaller-diameter corrugated pipes, the N-12 Dual-Wall HDPE pipe is an option. This pipe combines a corrugated exterior with a smooth interior wall, enhancing hydraulics and strength. The N-12 pipe is available in various joint options, including bell and spigot design, gasket, bell wrap, and pressure-rated 10.8 psi coupler.
Additionally, corrugated plastic pipes are marked with relevant standards, such as AASHTO and ASTM specifications. These markings indicate the quality and grade of the materials used, ensuring compliance with industry standards. For instance, the Pacific Corrugated Pipe Company's StormTite® HDPE pipe conforms to ASTM standards for corrugated polyethylene pipe, providing lightweight, flexible, and corrosion-resistant properties.

Spiral corrugated pipes can be up to 12-144 in diameter
Spiral corrugated pipes are an innovative design developed by the Pacific Corrugated Pipe Company. They are an efficient combination of the hydraulics of smooth wall pipe and the advantages of corrugated metal pipes. Spiral corrugated pipes can be up to 12-144 inches in diameter. They are lightweight, easy to transport, and can be assembled at any length, making them a convenient choice for construction projects.
The spiral design of these pipes provides superior strength and hydraulic efficiency. Featuring a helical pattern and lock-seam construction, these pipes are manufactured from high-quality galvanized corrugated sheets using advanced German technology. Spiral corrugated pipes are highly versatile and can be connected using coupling systems or flange plates, depending on the specific project requirements.
These pipes offer exceptional flexibility, with various wall thicknesses, pipe diameters, and corrugation wave sizes available to meet diverse construction needs. They are an excellent alternative to reinforced concrete (RCP) and corrugated metal pipe (CMP) due to their superior corrosion and abrasion resistance. Spiral corrugated pipes are widely used in drainage systems, storm sewers, agricultural irrigation, municipal engineering, and underground cable protection, among other applications.
The diameter of spiral corrugated pipes typically ranges from 12 inches to 144 inches, with smaller or larger sizes also possible depending on the producing facility. The corrugation patterns can be customized to fit the specific requirements of a project, and the pipes are usually fabricated in 20-foot sections, although other lengths are available upon request.

Corrugated pipes are lightweight, easy to transport, and fast to install
Corrugated pipes are a popular choice for drainage systems, offering many benefits over conventional materials like steel and concrete. One of their standout features is their lightweight construction, which makes them easy to transport and install. This weight advantage is due to their design, which incorporates a high-density polyethylene pipe with inset corrugation, providing flexibility and strength without the need for a heavy structure.
The lightweight nature of corrugated pipes has a significant impact on project costs. Reduced weight means lower transportation costs and easier handling on-site, requiring less manpower and resulting in faster installation times. This speed of installation is a notable advantage, especially when compared to solid PVC pipes, which often require multiple connections and can be challenging to work with.
Corrugated pipes' flexibility and ease of installation make them ideal for projects with lots of angles, bends, and twists. They are also a popular choice for DIY enthusiasts due to their user-friendly nature and lower cost. Additionally, their lightweight design does not compromise strength or durability. The corrugated structure provides impact resistance, enabling the pipes to withstand unfavourable conditions and extend their service life.
The benefits of corrugated pipes extend beyond their lightweight and easy installation. Their corrugated design improves self-cleaning capabilities, a crucial advantage for drainage systems. The structure also allows for varying trench designs, providing flexibility during installation and ensuring cost-effectiveness. Furthermore, corrugated pipes offer superior corrosion and abrasion resistance, making them an excellent alternative to reinforced concrete and corrugated metal pipes.

Corrugated pipes offer superior corrosion and abrasion resistance
Corrugated pipes are widely used for drainage systems, sewage management, ventilation systems, and cable protection. They are also used in floating systems in marine applications, such as docks and platforms.
Additionally, the corrugated design enhances the pipe's structural strength and flexibility. The corrugations allow the pipe to bend without breaking, making it well-suited for installation in areas with uneven terrain or shifting ground. This flexibility also enables the pipe to relax under stress, contributing to its long-term stability and resistance to collapsing under typical load conditions.
Corrugated metal pipes (CMPs) also offer corrosion and abrasion resistance, especially when coated with protective agents. For instance, aluminium alloy CMPs are designed to resist corrosion and abrasion underground. Aluminized steel CMPs, which are steel pipes coated in commercially pure aluminium, are effective in combating corrosion, especially in systems involving acidic water. Asphalt-coated galvanized steel pipes are another variation that delays corrosion and provides additional abrasion resistance by preventing water, debris, and abrasive runoff from reaching the base layer of steel.
Furthermore, polymeric coatings on CMPs offer excellent protection against abrasion and corrosion. This helps to maintain the structural integrity of the pipes and prevent issues such as voids or total structural failure due to corrosion and abrasion.

Frequently asked questions
The diameter of corrugated plastic pipes varies depending on the specific product and application. Common internal diameters for corrugated plastic pipes range from 3 inches to 24 inches. Some larger pipes can have diameters ranging from 8 inches to 60 inches.
The smallest diameter commonly available for corrugated plastic pipes is 3 inches.
Yes, corrugated plastic pipes can be categorized into two main types: Type C and Type S. Type C pipes have a single wall with a corrugated interior, while Type S pipes have a double wall with a smooth interior.
Type C corrugated plastic pipes offer superior flexibility and ease of installation due to their single-wall construction. They are often used in applications where space is limited or where the pipe needs to navigate tight bends.
Type S corrugated plastic pipes provide enhanced strength and durability thanks to their smooth interior wall. This design improves hydraulics and increases flow capacity, making them ideal for applications requiring higher fluid velocities or corrosion resistance.
