CHEMICAL AND CORROSION RESISTANCE
Anti-Corrosion Cast Iron Pipes: Superior Durability and Chemical Resistance
Cast iron drainage systems have been the go-to solution for decades due to their unmatched durability, resistance to harsh chemicals, and ability to withstand extreme environments. Our Pam Building cast iron pipes are designed to offer superior chemical and corrosion resistance, making them ideal for demanding applications such as commercial buildings, industrial facilities, and coastal installations.
Why Choose Cast Iron for Chemical and Corrosion Resistance?
Unlike plastic and other metal alternatives, cast iron has inherent resistance to chemical degradation and corrosion, ensuring long-term reliability. Our EN 877-compliant pipes provide a robust solution for the transportation of waste, rainwater, and aggressive effluents.
Key Features of Our Anti-Corrosion Cast Iron Pipes
| Feature | Advantage |
|---|---|
| Resistance to hot water | Can withstand continuous exposure to water at 95°C for 24 hours |
| Resistance to thermal cycles | 1,500 cycles between 15°C and 93°C |
| pH tolerance range | Resistant to effluents ranging from pH 2 to pH 12 (up to pH 13 for intensive applications) |
| Resistance to external corrosion | External coatings tested for 2,500 hours under neutral salt fog (NF-EN ISO 9227_2017 standard) |
| Zinc and epoxy coatings | Two-layer internal epoxy protection (thickness 130-250 μm) prevents internal corrosion |
Application Areas for Corrosion-Resistant Cast Iron Pipes
Our products are used in the most demanding environments, where corrosion prevention techniques are not optional, but essential:
-
Industrial Facilities: Effective against high-temperature effluents and aggressive chemicals.
-
Hospitals & Laboratories: Ensures safe discharge of contaminated waste.
-
Commercial Buildings: Durable for high-traffic installations with minimal maintenance.
-
Coastal & Underground Installations: Resilient against salt mist, humidity, and soil acidity.
INTENSIVE USE : INTERNAL STRESSES DUE TO AGRESSIVE EFFLUENTS
Solution : Plus Range
Aggressive effluents (acids, bases, hydrocarbons, etc.) can cause pipe degradation and reduce lifespan. Our Plus Range, formed for demanding wastewater environments, provides:
- Resistance to hot water: 24h at 95°C and thermal cycles (1,500 cycles, 15–93°C)
- External coating tested under neutral salt spray (NF-EN ISO 9227_2017): 2,500 hours
- Stable chemical resistance: 1 < pH < 13
These features protect the pipe structure, prevent leaks, and secure surrounding walls and property against damage.

Cataphoresis Coating: Advanced Corrosion Protection
Cataphoresis Coating: Advanced Corrosion Protection
To extend product longevity and maximize corrosion prevention, Pam Building applies cataphoresis coating to fittings and accessories. This technology enhances resistance in anti-corrosion cast iron pipe systems with:
- Electrochemical deposition: Uniform epoxy layer shields internal surfaces
- Superior adhesion: Bonds at micro level to resist peeling and long-term degradation
- Enhanced resistance: Protection against electrochemical reactions in metals, moisture, temperature changes
This coating ensures all components resist environmental impacts and aggressive agents, maintaining integrity over the long term—even in water quality-compromised zones.
This cutting-edge technology ensures that all components maintain their integrity, even in the most aggressive environments, extending the lifespan of your drainage system.
External Protection for Harsh Environments
Solution : Zn Range
For extreme conditions such as industrial zones and coastal areas, our Zn range pipes offer:
-
External flame-applied zinc metal coating (260 g/m²) to combat corrosion.
-
Superior salt mist resistance for marine applications.
Frequently Asked Questions (FAQ)
1. How long do cast iron pipes last in corrosive environments?
With proper coatings and maintenance, cast iron pipes can last over 70 years, even in aggressive environments.
2. Are cast iron pipes suitable for underground installations?
Yes. They are resistant to soil acidity and external mechanical stresses, making them an ideal choice for underground drainage systems.
3. How do Pam Building pipes compare to plastic alternatives?
Cast iron offers superior durability, chemical resistance, and fire safety compared to plastic pipes, which are prone to deformation and chemical degradation.
4. What maintenance is required for corrosion-resistant cast iron pipes?
Minimal maintenance is required, mainly periodic inspections to ensure coatings remain intact.
5. Can cast iron pipes handle high-temperature waste?
Yes. Our pipes can withstand continuous exposure to 95°C water and are tested for 1,500 thermal cycles.
