Ductile Iron (DI) Dismantling Joints are double-flanged fittings designed to simplify the installation and removal of valves, pumps, and meters in pipelines by providing longitudinal adjustment. Made from high-strength ductile iron (GJS-500-7) with EPDM seals, they offer corrosion resistance, 50-100mm+ axial movement, and pressure ratings up to PN10/16/25.

• Easy Installation/Maintenance: Allows for easy assembly and disassembly of flanged pipework, reducing downtime for repairs.
• Longitudinal Adjustment: Telescopic design compensates for axial movement during installation.
• Durable Construction: Typically constructed with epoxy-coated Ductile Iron for corrosion resistance and high strength.
• Tight Sealing: Uses resilient EPDM or NBR rubber seals for a leak-proof joint.
• End-Load Resistant: Features tie rods (often high-tensile steel or stainless steel) that lock the joint at the required length, allowing it to withstand pressure.
• Standards: Manufactured to comply with ISO, EN, BS, and AWWA standards. 

• Water and Wastewater Systems: Ideal for municipal water supply and treatment plants.
• Industrial Piping: Suitable for connecting valves, pumps, and flow meters in various, including high-pressure, systems.
• Infrastructure Projects: Used in new installations and retrofits. 

• Material: Ductile Iron GGG50 (GJS-500-7).
• Pressure Ratings: Typically PN10, PN16, PN25, or PN40.
• Sizes: Ranging from DN50 up to DN2000 or more.
• Coating: Fusion-bonded epoxy.
