Clamp-Type

expansion joint

The Rubber Clamp-Type Expansion Joint is constructed with molded elastomeric beads on both ends, which are clamped directly to the pipe or equipment nozzles using galvanized or stainless-steel clamps. This design eliminates the need for flanges, making installation simple and cost-effective. It provides axial, lateral, and angular flexibility while damping vibration and noise. Clamp-type joints are ideal for small- to medium-diameter pipelines, particularly where frequent installation or replacement is required.

  • Size Range (DN)

    DN25 – DN600 (larger on request)

  • Materials (Elastomer)

    Natural Rubber, EPDM, Nitrile, Neoprene

  • Reinforcement

    Nylon tire cord with steel wire

  • Movements

    Axial, Lateral & Angular

  • Pressure Rating

    PN6 – PN10 (higher on request)

  • Temperature Range

    –20°C to +100°C (up to +120°C with special elastomers)
