| Feature | Standard Cast Iron | Malleable Iron Fittings |
|---|---|---|
| Durability | Moderate / Brittle | High / Impact Resistant |
| Corrosion Life | Short (Standard) | Long (Hot-dip Galvanized) |
| Installation Speed | Slow (Fitting Issues) | Rapid (Precision Threads) |
| Pressure Loss | Higher Turbulence | Minimized (Smooth Bore) |
| Maintenance Cost | Frequent Replacement | Low Lifecycle Cost |
Malleable iron undergoes a specialized annealing process that removes brittleness, making it much more resistant to impact and pressure compared to standard grey cast iron.
Hot-dip galvanizing creates a thick, bonded zinc coating that protects the iron from oxidation and corrosion, significantly extending the product's life in humid or industrial environments.
Yes, due to their high pressure resistance and structural stability, they are ideal for fire protection system pipeline renovation and diameter conversion.
Our fittings meet national and international standards for pipe threads, ensuring full interchangeability with other standard pipe components.
While our precision threads provide a tight fit, using high-quality sealing materials (like PTFE tape or pipe sealant) during installation will ensure a 100% leak-proof effect.
They are best suited for HVAC interfaces, building water supply/drainage, and industrial pipe reductions where installation space is limited.
