Threaded steel pipe 6040 ZNM S 6040 ZNM_S

Steel electrical conduit – reliable cable protection

Threaded steel pipe 6040 ZNM S is a solid and durable solution for mechanical protection of cables and wires in electrical installations. Made of rolled steel with a galvanized coating, it provides long-lasting resistance to corrosion and mechanical damage. It is an essential element for both professional installers and demanding home installations.

Construction and application

The pipe is characterized by an outer diameter of 40 mm and an inner diameter of 34.4 mm, allowing for free cable routing. The metric external thread facilitates connection with other installation elements, and the coupling ensures a tight connection. Thanks to its rigid construction, the pipe works perfectly in surface-mounted installations, as well as in machine and equipment installations and on wood. The possibility of mounting in hollow walls further increases its versatility. The pipe is designed to operate in a wide temperature range, from -45°C to 250°C.

Key features and benefits

• Strength: Compression resistance class according to EN 61386-1 – Very heavy (Class 5) guarantees resistance to high mechanical loads.
• Corrosion resistance: Hot-dip galvanizing and galvanized zinc coating provide effective protection against atmospheric factors and corrosion.
• Versatility: Can be used in various types of installations – surface-mounted, concealed (in combination with appropriate accessories), in concrete, on wood, and in machine and equipment installations.
• Safety: Provides mechanical protection of cables against damage, minimizing the risk of short circuits and fires.
• Durability: Made of high-quality rolled steel guarantees long life and reliability.
• Wide temperature range: Operation in the range of -45°C to +250°C allows the pipe to be used in various environmental conditions.

Additional information: when used with PVC end piece 4816E - 4863, the operating temperature range is reduced to -5 to +60 °C. Please note the limitations regarding the number of cables in the pipe in fire protection systems (maximum one cable). Detailed information can be found in the fire-resistant systems catalog.
