A Ductile Iron Dismantling Joint is a robust pipeline component combining the maintenance-friendly design of a standard Dismantling Joint with the strength and durability of ductile iron, engineered to simplify system repairs and component replacement. Its structure features two flanged ends—crafted from high-grade ductile iron—connected by an adjustable sliding sleeve, with bolts that regulate length, enabling controlled disassembly of pipeline sections without cutting or welding.

Ductile iron, known for its tensile strength, impact resistance, and corrosion tolerance, surpasses cast iron in durability, making this joint ideal for demanding environments. It handles high pressures and diverse media, including water, sewage, chemicals, and industrial fluids, resisting rust and wear even in harsh conditions like wastewater treatment plants or coastal infrastructure.

The adjustable design accommodates axial movements and minor misalignments, reducing stress on connected equipment during installation or operation. This versatility makes it indispensable in municipal water networks, industrial pipelines, and irrigation systems where reliability and low maintenance are critical.

In system integration, it works synergistically with key components: paired with a Butterfly Valve or Gate Valve, it simplifies Valve replacement by allowing sectioned access. It complements a Rubber Expansion Joint or Bellow Expansion Joint by providing maintenance access near flexible connectors. When used with a Flange Adaptor or Flexible Metal Hose, it bridges connections while enabling easy disassembly.

Key advantages include long service life, cost-effectiveness, and time-saving maintenance. The ductile iron construction ensures durability without excessive weight, while the adjustable design reduces installation errors. By combining strength with operational flexibility, it ensures efficient, leak-free performance, making it a cornerstone of modern industrial and infrastructure pipeline systems.

Ductile Iron Dismantling Joint

Ductile iron dismantling joint is a joint that adds a flange short tube and a force transmission screw on the basis of a flange loose sleeve compensation joint. Its main function is to provide adjustment during installation and disassembly. Once all nuts are tightened, the joint becomes a rigid connection and can transmit axial force, thereby protecting valves, pumps and other equipment. Ductile iron disassembly joints usually consist of a flange loose sleeve compensation joint, a flange short tube and a force transmission screw. Its design allows adjustment during installation and disassembly. Once the adjustment is completed and all nuts are tightened, the joint becomes a rigid connection and can transmit axial force.

Application areas

water supply and drainage systems, petrochemical systems, thermal systems, fire protection systems, etc.

Product Detail

Ductile iron dismantling joints consist of key parts such as long flange body, short flange body, middle flange, sealing ring, stud, gasket and nut. These parts work together to ensure the stability and sealing performance of the dismantling joint in the pipeline system.

Flange is the main connection part of the dismantling joint, which provides a connection interface with the pipeline or other equipment.

The sealing ring is located between the two flanges to ensure the sealing performance of the joint. It is usually made of elastic materials such as rubber or plastic, which can provide a tight seal when the flange is connected.

The gasket is usually located between the bolt and the nut to increase the stability of the connection and prevent loosening.

VOICE

WHAT A CLIENT SAY?

Customers generally believe that the sealing performance of ductile iron dismantling joints is excellent. Through the close fit of flange connection and sealing ring, the joint can effectively prevent the leakage of media during operation. This is especially important for pipeline systems that need to transport various corrosive, flammable, explosive or toxic media. Ductile iron dismantling joints are suitable for a variety of media and working environments. Customers said that the joint can transport seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, and steam and granular powder at a temperature not higher than 250°C. This wide applicability allows the joint to play an important role in various pipeline systems.
