GASKET CONNECTION

 

  1. Two gaskets per joint.
  2. Install the gaskets as shown in the figure.
  3. To facilitate the installation, it would be good if the ground around one of the pipes to be jointed could be partially backfilled as this ensures proper support during the jointing and prevents the pipeline from waving.
  4. Mark the spigot with waterproof marker on the length of the pipe which will enter the socket (at least 125mm).
  5. Cover the sockets and spigots with PLENTY of lubricant.
  6. The spigots and sockets must be kept clean during the lubrication as well as the jointing process.
  7. Joint the pipes up until the marked line on the spigot has been reached.
  8. During the jointing period a mechanical aid is needed. If you joint by pushing, a device to spread the pressure must be used (e.g. a wooden sheet), to prevent the socket from being damaged.
  9. Avoid dragging the pipe ends.
  10. Krah pipes with a gasket jointing are for use in straight pipelines. In cases where there is a curvature in the project, a pipe bend must be used.
