Cast Iron Soil Pipe & Aggressive DWV with Charlotte Pipe

This webinar explores the history and durability of cast iron piping while introducing enhanced coating technologies, like Charlotte Pipe’s Edge HP, designed to withstand modern corrosive environments. It also demonstrates how the ATS spec tool helps engineers maintain accurate, up-to-date product specifications for complex plumbing projects.

Key Takeaways

Durability & Sustainability

• Proven Longevity: Cast iron has been used for centuries; for example, the Palace of Versailles has had cast iron in service for 362 years, and the Smithsonian found 130-year-old pipe still met modern specs.
• Eco-Friendly: North American cast iron is made from 96% post-consumer recycled scrap and is 100% recyclable.Enhanced Protection for Aggressive Waste Edge HP Coating: Standard cast iron handles a pH of 4.3 to 10, but the Edge HP e-coat handles a pH range of 1 to 13, protecting against harsh chemicals and acidic waste.
• Critical Applications: Enhanced coatings are recommended for hospitals (due to low-flow sanitizers), commercial kitchens (to resist hydrogen sulfide gas), and parking garages (to combat road salts).
• Temperature Resistance: Cast iron handles up to 100°C, whereas common plastics like PVC or ABS are limited to 60°C and can lose structural strength at high temperatures.

Technical Installation Standards

• Precise Torque: Mechanical joint (MJ) couplings are torque-sensitive; standard couplings typically require 60 inch-pounds, while heavy-duty versions vary by manufacturer.
• E-Coat Advantage: Charlotte Pipe uses an electrostatic “e-coat” process that creates a molecular bond with the iron to prevent delamination, which can occur with traditional spray-on coatings.

ATS Spec Tool Benefits

• Automatic Updates: The tool sends push notifications if a specified product is discontinued or its model number changes, ensuring master specs stay current.
• Code Compliance: By selecting a project location, the tool automatically applies relevant building codes (e.g., Ontario or BC Building Codes) to product selections.
