Plastic pipes for protecting cables in the ground are available in a wide variety of diameters and wall thicknesses. One thing is the same in all cases: the cables inside the pipe are to be protected from environmental influences and damage. To ensure this, appropriate standards must be met that clearly specify the properties of the conduit.
Among other things, these standards specify the diameter/wall thickness ratio, which fixes the amount of material per running meter of pipe. To save costs, recyclates or B-goods are often used, whose property profile and processing characteristics are highly dependent on the batch.
