DN900 Dismantling Joint Overview
The DN900 dismantling joint is a specially designed fitting that provides flexible and secure connections between flanged pipes, valves, and pumps. Made of ductile iron (GJS400) and rated for PN10 pressure, this joint allows easy installation, adjustment, and maintenance in large-diameter pipeline systems. It helps to absorb axial movement and simplify the dismantling process of valves or equipment during service.
Durable Ductile Iron Construction
Manufactured from ductile iron GJS400, the DN900 dismantling joint offers exceptional mechanical strength, corrosion resistance, and durability. The high-grade iron body ensures reliable performance in both underground and above-ground installations, even under fluctuating pressure conditions.
The surface is coated with fusion bonded epoxy (FBE) for additional protection against rust and aggressive environments.
Reliable Sealing and Flanged Connection
This flanged dismantling joint features rubber sealing gaskets, stainless steel bolts, and a galvanized steel tie-rod system, ensuring tight and leak-free connections.
It accommodates slight pipe misalignments and provides flexibility during pipeline assembly, minimizing the stress on connected components.
