D Type expansion joints

Features

• - Transportation or piping systems that carry fluids, slurries or gasses under pressure or vacuum at varying temperatures
• - Reduction of vibration
• - Dampen sound transmission
• - Compensate movements due thermal changes, misalignments caused by wear, load stresses, settling of supporting foundations
• - Molding production with long radius arch
• - Standard measures (length)

Advantages

• Easy installation, flanges can be rotated; For installation with “torsional misalignments”; Flanges are not in contact with medium, which enables lower grade material; Galvanic surfaces/coatings possible; Gaskets can be eliminated; Additional movement capabilities; Self cleaning arch (no need filler material); Economic
