Corrugated conduits
Double-walled protective pipes - DUOFLEX and DUOHARD, hoses, plastic cable protectors - designed for mechanical protection of cables laid in trenches and cable ducts.
Parameters and temperature
- Use when passing the cable route through problematic sections (watercourses, railway crossings, if increased protection of water and gas pipelines, drainage or sewage systems is necessary)
- Material – DUOHARD: outer and inner wall made of PE-HD (High Density Poly Ethylene)
- Outer wall – Corrugated: increases the mechanical resistance of the pipe
- Inner wall – Smooth: enables easy cable installation. Slight corrugation ensures excellent flexibility and unimpaired pipe passage in bends while maintaining high strength
- External wall colors: red, black or blue
- Inner wall color: black
- Handling temperature: from -5°C to +50°C
- Operating temperature:from -40°C to +70°C
Installation and storage
- Tension element: DUOFLEX protective pipes have a tension element pre-installed in the coils (PV-PAD 1.2 mm thick or PP twine 12,500 dtex)
- Cable insertion: PULL only! (do not blow)
- Connecting pipes: using push-in couplings (each production length of pipe has a coupling installed at one end, which is included in the delivery)
- Storage of pipes: horizontal position at a maximum height of 2 meters
- Storage period: for as long as necessary, maximum 3 months
- Warning: Do not store in direct sunlight!
