Product Details

  • Implements a series of individually activated wedges into the mechanical joint follower gland, when the wedge segment is engaged by the actuating bolt, the primary contact edges of each wedge segment lock onto the pipe wall, this action causes the primary contact edges to grip the pipe and effectively restrain all classifications of ductile iron pipe
  • Precision contoured wedges provide proper contact and support of the ductile iron pipe wall, each wedge is manufactured with an elongated contour that evenly matches the outside circumference of each nominal diameter of ductile iron pipe
  • Elongated contour also eliminates the concern of damage to both the pipe wall and the interior cement mortar lining caused by point loading, even on the thinner pressure classes of ductile iron pipe
  • Wedge actuating bolt provides the installer with a visual torque indicator, the breakaway top ensures proper engagement of the wedge segment at the time of installation
  • Unique wedge segment and actuating bolt design allows the two components to interface using a cam action principle, allowing the wedge segments to rock and increase their grip on the pipe wall as thrust on the assembled joint increases
  • Also allows improved resistance to subsidence, seismic forces, and other movement within the maximum deflection limitations of the mechanical joint under applicable AWWA standard
