The corrosion allowance for ductile iron pipe refers to the additional wall thickness added during manufacturing to compensate for potential material loss over decades of service. Unlike steel pipes, modern ductile iron pipes (per AWWA C150/C151 standards) typically don’t require a corrosion allowance when properly protected with: Polyethylene encasement (ANSI/AWWA C105) Cement-mortar lining (AWWA C104) Advanced coatings like epoxy […]

In the world of materials science and engineering, understanding the phenomena of rust and corrosion is crucial for maintaining the longevity and integrity of metal structures. While often used interchangeably, rust and corrosion are distinct processes with different implications for materials. This comprehensive guide delves into their differences, causes, effects, and prevention methods. ​ What

While both oxidation and rust affect ductile iron, they represent distinct corrosion processes with different prevention strategies. Oxidation forms a protective patina (iron oxide layer) that slows further degradation, whereas rust (iron oxide hydroxide) is a destructive, flaky corrosion product caused by moisture and electrolytes. For ductile iron pipes, effective protection includes: Polyethylene encasement (AWWA C105) for buried pipes Epoxy/polyurethane coatings for exposed

Glass-lined ductile iron pipes are engineered to offer superior performance in challenging environments, particularly in wastewater and sewage systems. The fusion of ductile iron’s strength with the non-stick, corrosion-resistant properties of glass lining creates a piping solution that addresses common issues like scaling, clogging, and chemical degradation. This guide delves into the composition, applications, benefits,

Choosing the right paint for ductile iron pipes is essential to prevent corrosion, abrasion, and UV damage, extending the pipe’s lifespan in both buried and exposed applications. Common protective coatings include: Epoxy paints – Excellent chemical resistance for water/sewer systems Polyurethane coatings – UV protection for above-ground pipes Coal-tar enamel – Traditional corrosion barrier for buried infrastructure Zinc-rich primers – Enhanced rust inhibition
