DUOFLEX, DUOHARD protective pipes
Double-walled protective pipes (also called "corrugated pipes or "cable protection sleeves") are intended, primarlly, for mechanical protection of cables laid in excavations and cable trenches.
- Generally, they are used for difficult section of cable routes such as, water courses, railway, crossing, motorways.
- The pipes provide additional protection of water and gas supply lines, drainage or sloped sewers.
Material
- DUOHARD - outer and inner walls are made of PE-HD.
- DUOFLEX - outer walls are made of PE-HD, inner wall are made of PE-LD (for diameters of 40, 50 and 63 mm) and of PE-HD (for diameters from 75 mm).
Pipe design
- outer wall - corrugated for higher mechanical strength of the pip.
- inner wall - smooth for easy cable installation. Slight corrugation provides for excellent flexibility, does not reduce passage capacity through the pipe in bends and maintains high strength.
Colour design
- outer wall - red, black or blue (standard colours)
- inner wall - black (standard)

Heat resistance
- installation temperature: dandling PE-HD pipes within of -5ºC to + 50ºC
- operation temperature: of -40ºC to +70ºC
Pipe connection
- the pipes are connected using slide-on couplings
- pipes of both production lengths are delivered with a coupling on one end
Drawing element and cable introduction
- DUOFLEX protective pipes in coils have pre-installed drawing elements (PV-PAD, thickness 1,2 mm or PP string 12 500 dtex)
- cables must be introduced into DUOFLEX and DUOHARD pipes via drawing (blowing-in not possible). Smooth inner walls provide for easy cable introduction into the pipe.
Storage
- in horizontal position, maximum storage height 2 m
- max storage time up to 3 months
- it is not recommended to store in direct sunlight (to DN 160 does not contain UV stabilizer)
Pipe laying
- in order to maintain maximum mechanical strength of DUOFLEX and DUOHARD protective pipes observe installation instructions issued by MATEICIUC a.s.
