Types of Ductile Iron Pipe Fitting

The ductile iron pipe fitting produced by our company mainly include the following types:

Flanged Fittings

Our DI Flange Fittings ensure secure pipeline connections. They join pipes perfectly. These fittings feature flanged ends. Use them in water systems. Install in industrial plants. Apply for fire protection.

Socket Fittings

Our DI socket fittings feature EX joints. This system provides superior performance. These fittings ensure perfect connections. They work with all ductile iron pipes. Choose our advanced joint solutions.

Advantages of Ductile Iron Pipe Fitting

High Strength-to-Weight Ratio

Ductile iron is nearly 30% stronger compared to conventional cast iron, allowing for thinner wall thicknesses and lighter fittings without compromising strength.

Corrosion Resistance

With a coating that effectively protects against corrosive environments, these fittings offer an average lifespan improvement of 100% compared to uncoated alternatives.

Impact and Fatigue Resistance

Ductile iron can endure significant impacts and vibrations, making it ideal for urban environments where ground movement may occur.

Sustainability

Ductile iron fittings are often made from recycled materials, aligning with sustainable construction practices.

Applications of Ductile Iron Pipe Fitting

Stormwater Systems
Ductile iron fittings help regulate water flow while withstanding erosion, from fast-moving water streams. Their durability ensures they can manage amounts of water without faltering during rainstorms.

Wastewater Systems
Ductile iron fittings are withstanding corrosion, from sewage and industrial waste products.

Irrigation Systems
Ductile iron fittings play a role, in ensuring the distribution of water over expansive fields. Their ability to withstand strain caused by machinery and environmental elements.

Types of Connections for Ductile Iron Pipe Fittings

Ductile iron fittings have different ways to connect:

Socket fittings use push-in or mechanical joints. They are easy to set up.

Flanged fittings have flat surfaces with holes for bolts. They make strong connections.

Grooved fittings use couplings for quick setup.

Surface Treatment of Ductile Iron Pipe Fittings

ASTM A53

ASTM A53 is a specification for carbon steel pipe used in a variety of applications, including ductile iron grooved fittings. It outlines the chemical composition, mechanical properties and testing requirements for pipes.

Electroplated painted

Electroplated painted is the process of applying a charged coating solution to a conductive surface such as ductile iron pipe fittings. This process provides a uniform and corrosion-resistant coating.

Electroplated

Electroplating is the process of applying a metallic coating to a surface using an electric current. In the case of ductile iron pipe fittings, electroplating can be used to provide a decorative or protective coating, such as chrome plating.

Epoxy

Epoxy coatings are often used on ductile iron pipe fittings to provide corrosion resistance. Epoxy coatings are applied as a two-part system to provide a long-lasting protective barrier against chemicals, water, and other corrosive substances.

Hot dip galvanized

Hot dip galvanizing is a process of plating a layer of zinc on the surface of ductile iron pipe fittings. The process provides a corrosion-resistant coating that protects accessories from rust and other environmental damage.

FAQ

Q: How long do ductile iron fittings last?

A: On average, ductile iron fittings can last over 100 years when properly maintained, significantly reducing replacement costs.

Q: Are ductile iron fittings resistant to corrosion?

A: Yes, ductile iron fittings have a protective coating that enhances their corrosion resistance, enabling use in diverse environments.

Q: What sizes can a ductile iron pipe fitting cover?

A: A ductile iron pipe fitting is available from DN80 to DN2000. Different sizes allow smooth connection between pipes in small networks and large municipal pipeline systems.

Q: What standards are used for ductile iron pipe fitting?

A: A ductile iron pipe fitting is produced under ISO 2531, EN 545, EN 598, or AWWA standards. These standards ensure quality, strength, and reliable performance.

Q: What gaskets are used with ductile iron pipe fitting?

A: A ductile iron pipe fitting usually uses EPDM or NBR rubber gaskets. These gaskets provide good sealing and prevent leakage under working pressure.

Q: What angles are available for ductile iron pipe fitting elbows?

A: Ductile iron pipe fitting elbows are available in 11.25°, 22.5°, 45°, and 90°. These angles help adjust pipeline direction smoothly.
