1. Material Excellence
Crafted from high-strength ductile iron conforming to ASTM A536 standards (Grades 60-42-10, 65-45-12, or 70-50-05), these fittings offer superior tensile strength and impact resistance compared to traditional gray iron, making them ideal for demanding environments.
2. Pressure Ratings
The fittings are rated for water working pressures up to 250 psi for sizes ranging from 2″ to 48″. For sizes 54″ to 64″, the pressure rating is 150 psi. Notably, ductile iron flanged joints in sizes 24″ and smaller may achieve a 350 psi rating when equipped with special gaskets.
3. Standard Compliance
These fittings adhere to the following industry standards:
-
ANSI/AWWA C110/A21.10 – Ductile-Iron and Gray-Iron Fittings for Water Service.
-
ANSI B16.1 – Cast Iron Pipe Flanges and Flanged Fittings, Class 125.
-
ANSI/AWWA C104/A21.4 – Cement-Mortar Lining for Ductile-Iron Pipe and Fittings for Water Service.
-
ANSI/AWWA C111/A21.11 – Rubber-Gasket Joints for Ductile-Iron Pressure Pipe and Fittings.
These certifications ensure the fittings meet stringent quality and performance criteria.
4. Versatile Applications
C110 flanged fittings are suitable for a wide range of applications, including:
-
Municipal water supply and distribution systems.
-
Industrial piping networks.
-
Fire protection systems.
-
Wastewater treatment facilities.
Their robust design ensures long-term reliability and minimal maintenance requirements.
5. Coatings and Linings
To enhance corrosion resistance and extend service life, these fittings come with:
-
Cement-mortar lining on the interior, in accordance with ANSI/AWWA C104/A21.4.
-
Seal coating on the interior surface, providing additional protection against corrosive elements.
-
Red primer on the exterior, offering a protective barrier against environmental factors.
Special coatings and linings are available upon request to meet specific service conditions.
6. Design and Construction
These fittings feature:
-
Flat-faced flanges without projections or raised faces, ensuring uniform gasket compression and leak-proof seals.
-
Smooth or shallow serrated surfaces to facilitate effective sealing.
-
Back or spot facing as necessary to comply with flange thickness tolerances.
7. Testing and Quality Assurance
Each fitting undergoes rigorous testing to verify its performance and durability:
-
Hydrostatic testing to ensure leak-proof integrity.
-
Heat coding for traceability and verification of metallurgical properties.
-
Compliance with NSF/ANSI 61 standards, ensuring suitability for potable water systems.
C110 Ductile Iron Full Body Flanged Fittings represent the pinnacle of strength, reliability, and compliance in water distribution infrastructure. Their superior material properties, adherence to industry standards, and versatile applications make them an excellent choice for engineers and contractors seeking durable and high-performance piping solutions.
