A dismantling joint is a double-flanged fitting used in pipe systems. Here are some key points about it:

  1. Purpose:

    • Facilitates the installation or removal of flanged equipment (such as valves) within a pipeline.

    • Allows longitudinal adjustment (up to ±25 mm) for flexibility.

  2. Benefits:

    • Simplifies maintenance by self-anchoring connections (no need for concrete anchor blocks).

    • Ideal for subsequent equipment adjustments or replacements.

  3. Materials:

    • Typically made of ductile iron.

    • Consists of flange spigot, flange adaptor, and tie rods (bolts, nuts, and washers).
