Ductile Iron Pipe Joints Universal Coupling Wide Range Model DN40

Product details

Ductile Iron Universal Joint Pipe Coupling (Model DN40). This DN40 model ductile iron universal joint pipe coupling is engineered to connect pipe sections within a diameter range of 48-60mm. Its core universal joint mechanism, featuring precision cross-pin bearings, provides exceptional flexibility, accommodating significant angular deflection, axial movement (compression/extension), and limited parallel offset. Constructed from high-grade nodular cast iron, the coupling offers superior tensile strength, impact resistance, and durability compared to standard grey iron, making it ideal for demanding high-pressure applications (e.g., water mains, industrial process lines, pump discharge systems). The robust ductile iron housings securely integrate with pipe spigots or sockets. Key functions include: Compensating for pipeline misalignment during installation or settlement. Absorbing vibrations and thermal expansion/contraction stresses. Protecting connected equipment (pumps, valves, turbines) from harmful forces. Designed for critical infrastructure like potable water networks, wastewater systems, and industrial plants, the DN40 model ensures reliable performance under harsh conditions. Regular lubrication of the universal joint bearings is recommended to maintain optimal articulation and extend service life. Its 48-60mm diameter compatibility offers versatile connection solutions for standard piping within this range.
