Protecto 401™ Lining: Long-Term Protection for Waterworks Infrastructure
In the waterworks industry, corrosion is the silent killer of infrastructure. Over time, unprotected pipes and fittings—especially in sanitary sewer systems—face chemical attack and deterioration. That’s why Protecto 401™ Ceramic Epoxy Lining has become the go-to solution for municipalities and contractors aiming to extend the life of their ductile iron pipe systems.
At Custom Pipe & Fabrication, we provide ductile iron spools, fittings, and other components lined with Protecto 401™ to help our customers meet demanding performance standards and regulatory requirements.
What Is Protecto 401™?
Protecto 401™ is a ceramic-filled epoxy lining specifically formulated to protect the interior of ductile iron pipe and fittings in sewer and wastewater systems. It is highly resistant to:
- Hydrogen sulfide (H₂S) corrosion
- Microbial-induced corrosion (MIC)
- Harsh industrial waste environments
- Chemical attack from sulfates, acids, and more
This advanced epoxy lining bonds tightly to the interior surface of the pipe, creating a smooth, highly durable barrier that stands up to aggressive conditions over decades of use.
Key Benefits of Protecto 401™ Lining
1. Superior Corrosion Resistance
Protecto 401™ shields pipe interiors from sulfuric acid and hydrogen sulfide gas—common byproducts in sanitary sewer environments.
2. Extended Pipe Life
By protecting against corrosion, erosion, and chemical degradation, Protecto 401™ can significantly increase the service life of ductile iron pipe systems.
3. Smooth Interior Surface
The ceramic epoxy lining reduces friction and improves hydraulic efficiency, allowing water and wastewater to flow more freely through the system.
4. Industry-Proven Performance
With over three decades of proven use, Protecto 401™ is trusted by engineers, municipalities, and contractors across North America.
5. Regulatory Compliance
It meets or exceeds the requirements of many federal, state, and local waterworks specifications, making it suitable for public infrastructure projects.
Common Applications
- Protecto 401™ lined components are ideal for:
- Sanitary sewer systems
- Wastewater treatment plant piping
- Force mains
