OPTOHARD protective pipes

OPTOHARD protective pipes

Single-walled protective pipes are intended, primarily, for mechanical protection of optical and coaxial cables laid in trenches and channels (building/ reconstruction of transmission lines).

  • allow for trouble-free cable installation at long distances (on ideal conditions, up to 3 000 m)
  • cable introduction into the pipe via drawing or blowing-in technology


  • high-density polyethylene (PE-HD)

Pipe design

  • outer wall - smooth
  • inner wall - smooth or longitudinal grooving
outer diameter (mm) 32 40 50
standard wall thickness (mm) 2,5 3,0 3,5 4,0
Temperature resistance
  • installation temperature: handling HDPE pipes within of -5ºC to + 50ºC
  • operation temperature: of -40ºC to +70ºC

Pipe connection

  • mechanical couplings

Colour design

  • based on customer request


  • on request by the customer, the pipes of the same colour be differentiated using one, two or three longitudinal stripes around the pipe (90º intervals)
