The Versatitlity and Benefits of Pex Tubing
March 11, 2025At Midwest Municipal Supply, we’re committed to providing our customers with the most innovative and effective solutions for their water management needs. Today, we’re excited to spotlight a product that’s changing the game in culvert and drainage systems: the ADS N-12 Dual Wall Pipe.
What is the ADS N-12 Dual Wall Pipe?
The ADS N-12 is a high-density polyethylene (HDPE) dual wall corrugated pipe that offers a unique combination of strength, durability, and hydraulic efficiency. This versatile pipe ranges from 4 inches to 60 inches in inside diameter, making it suitable for a wide variety of applications.

Also known as HDPE culvert or dual wall pipe, the N-12 is designed to meet the demanding requirements of modern water management systems. Its innovative design features a smooth interior wall and a corrugated exterior, providing the best of both worlds in terms of flow capacity and structural integrity.
The Benefits of ADS N-12 Dual Wall Pipe
1. Exceptional Hydraulics
The smooth interior wall of the N-12 pipe allows for superior water flow compared to traditional corrugated pipes. This improved hydraulic performance means that water can be moved more efficiently, reducing the risk of backups and flooding in your drainage systems.
2. Impressive Strength
Despite its lightweight nature, the N-12 pipe boasts remarkable strength. The corrugated exterior provides excellent structural support, allowing the pipe to withstand heavy loads and soil pressures. This makes it an ideal choice for applications beneath roads, driveways, and other high-traffic areas.
3. Corrosion and Abrasion Resistance
One of the standout features of the N-12 pipe is its superior resistance to corrosion and abrasion. Unlike metal pipes that can rust over time, or concrete pipes that can degrade due to chemical exposure, the HDPE material of the N-12 pipe remains intact and functional for decades. This resistance to deterioration ensures a longer service life and reduced maintenance costs.
4. Lightweight and Easy to Install
The N-12 pipe’s lightweight nature makes it significantly easier to transport and install compared to traditional materials like reinforced concrete pipe (RCP) or corrugated metal pipe (CMP). This not only reduces installation time but also lowers labor costs and minimizes the need for heavy machinery during the installation process.
5. Flexibility and Joint Integrity
The flexible nature of HDPE allows the N-12 pipe to adapt to ground movements and settling without cracking or breaking. Additionally, the pipe features a bell and spigot joint system that ensures a secure, watertight connection between pipe sections, reducing the risk of leaks and infiltration.
6. Wide Range of Applications
The versatility of the N-12 pipe makes it suitable for numerous applications, including:
- Storm sewer systems
- Culverts under driveways and roads
- Agricultural drainage
- Highway edge drains
- Mining and forestry applications
- Stormwater detention and retention systems
7. Environmentally Friendly
The N-12 pipe is made from recycled materials and is itself recyclable at the end of its service life. This makes it an environmentally responsible choice for municipalities and contractors looking to reduce their environmental impact.

Compatibility and Accessories
One of the key advantages of the ADS N-12 pipe is its compatibility with a wide range of fittings and accessories. These include:
- T’s and Y’s for creating branch connections
- Reducers for transitioning between different pipe sizes
- Elbows of various degrees for changing flow direction
- Couplers and adapters for connecting to other pipe materials
This compatibility ensures that you can design and implement complex drainage systems with ease, using a single pipe system throughout your project.

Applications of ADS N-12 Dual Wall Pipe
The N-12 pipe excels in various applications, particularly in directing water away from unwanted areas. Some common uses include:
- Driveway Culverts: The N-12 pipe is perfect for channeling water underneath driveways, preventing erosion and maintaining proper drainage.
- Storm Drainage Systems: In urban and suburban areas, the N-12 pipe is widely used in stormwater management systems, efficiently moving rainwater away from streets and properties.
- Field Crossings: For agricultural applications, the N-12 pipe provides an excellent solution for managing water flow across fields, enabling better land use and preventing waterlogging.
- Highway Drainage: The pipe’s strength and durability make it ideal for use in highway drainage systems, where it can withstand heavy loads and provide long-lasting performance.
