4. Pressure Ratings and Performance
The pressure rating of Clow ductile iron fittings is a crucial factor when selecting the right fitting for an application. The fittings are designed to handle pressures ranging from 150 psi up to 350 psi, depending on the specific product and size. The pressure ratings ensure the fittings can withstand the demands of both municipal and industrial applications, ensuring reliable performance under high pressure.
For example, Clow fittings used in fire protection systems are designed to endure high pressure from water sources to hydrants, while those used in residential water distribution systems are rated for moderate pressures. The fittings are also highly resistant to external forces, making them suitable for underground installation in urban environments or harsh industrial settings.
5. Material Specifications and Coatings
Clow ductile iron fittings are made from high-quality ductile iron, which provides superior strength, flexibility, and impact resistance compared to traditional cast iron. The material properties of ductile iron include:
-
Tensile Strength: Ductile iron has high tensile strength, meaning it can withstand heavy loads and stress without cracking or breaking.
-
Ductility: The material’s ability to bend without fracturing makes it ideal for use in environments where flexibility is required.
-
Corrosion Resistance: Clow fittings are coated with a corrosion-resistant lining, such as cement mortar or epoxy coatings, to protect them from rust and degradation over time.
These materials ensure that Clow fittings remain durable and effective even in challenging environments, providing long-lasting performance with minimal maintenance.
6. Pricing and Cost Factors
The cost of Clow ductile iron fittings varies based on size, type, and application. Prices can range from $10 to $300 or more per fitting, depending on the complexity and material requirements.
The main factors influencing the price of these fittings include:
-
Size: Larger fittings tend to cost more due to the increased amount of material required.
-
Type: Specialized fittings, such as flanged fittings or tees, tend to be more expensive than basic couplings and elbows.
-
Coating: Fittings with advanced corrosion-resistant coatings, such as epoxy, may be priced higher due to the added protection they offer.
-
Quantity: Bulk purchases often result in discounts, making large projects more cost-effective.
Overall, the cost of Clow ductile iron fittings represents a good value given their longevity, reliability, and performance.
