1.3 Groundwork

Pipes are laid in trenches in the ground. It is most practical to lay the excavated ground alongside the trench. The following steps are a summary of the basic pipe installation procedure:

  • Position the coil alongside the trench
  • Remove the packaging
  • Place the end of the pipe in position
  • Cut the outermost straps
  • Roll the pipe alongside or straight into the trench
  • Cut the middle straps
  • Roll out further
  • Cut the innermost straps
  • Roll out completely
  • Apply the dust caps or shrink caps
  • Connect your pipes with couplings
  • Conduct the pressure test – fill in the report
  • Fill the trench with a first layer
  • Apply the warning tape
  • Fill up the trench.
The following guidelines should be followed during pipe installation:
 
  • Lay the pipes in a bed of sand
  • Avoid damaging the casing, remove sharp objects from the ground
  • Always grasp the transport pipe and not the outer tube
  • Keep to the stated bending radii
  • Lay the pipe with a slight curve bending from one side of the trench to the other
  • Sketch how and where the pipe network runs on a plan, which you should keep.
