Protective Smooth Conduit Pipe Kopos RHDPE 110x5.5 mm DNK L=6, blue two‑colour

Kopos Protective Smooth Conduit Pipe in RHDPE is a rigid plastic conduit with a nominal diameter of 110 mm and a wall thickness of 5.5 mm, supplied in 6 m lengths. The two‑colour blue finish provides easy visual identification of the duct route. The pipe is designed for protection and routing of electrical and telecommunication cables in underground trenches and within building structures where a durable, impact‑resistant conduit is required.

Advantages

The RHDPE material offers good mechanical strength and resistance to external loads, chemical influence and moisture, ensuring long service life in buried or indoor installations. The smooth internal surface reduces friction when pulling cables and facilitates cable installation and later replacement. The two‑colour blue finish simplifies system identification and organization of duct networks. The rigid design maintains shape under backfill and traffic loads while remaining lightweight for easier handling on site.

Suitable for

• Protection and routing of electrical power and control cables
• Telecommunication and fiber optic cable routing in conduit systems
• Underground ducting in trenches and service corridors
• Building installations where rigid, durable conduits are required

• Nominal internal diameter: 110 mm
• Wall thickness: 5.5 mm
• Length: 6 m per pipe
• Finish: two‑colour blue for identification
• Internal surface: smooth for reduced cable friction
• Suitability: designed for buried and indoor installations

How to use

Select conduit runs and fittings appropriate to the installation layout and local regulations. Cut the 6 m pipe to required lengths with suitable tools, deburr pipe ends and ensure clean mating surfaces before assembly. Use compatible couplers, bends and seals to connect pipe sections and to provide watertight transitions where required. Support and secure the conduit at regular intervals, protect exposed ends during backfilling, and mark conduit routes for future access. When pulling cables, use lubricant recommended for polyethylene conduits if necessary and avoid sharp bends and excessive pulling tension.

Usage recommendations

Store pipes horizontally on a flat surface out of direct sunlight when long-term storage is required. Follow local electrical and telecommunications installation standards for burial depth, separation from other services and mechanical protection. Inspect conduit runs after installation for correct alignment, clean interiors and secure connections before cable pulling.
