Corrugated halogen-free conduit without pull cord (halogen-free flexible conduit) RIS-HF-FR E25 (21x25) colour RAL 7035, crush resistance 750N 50m W4524

Halogen-free corrugated pipe for electrical installations

This halogen-free corrugated pipe, with a diameter of 21x25 mm and RAL 7035 color, is a reliable solution for protecting cables in electrical installations, especially where high fire resistance and minimal emission of toxic substances during combustion are required. Made of polypropylene (PP), it provides flexibility and ease of installation. It is a product dedicated to both professionals and end-users looking for a safe and durable solution.

Properties and application

The pipe is designed for laying and securing electrical cables in places with increased fire safety requirements. Thanks to its self-extinguishing properties (HB according to UL94), it limits the spread of fire, and the absence of halogen in its composition minimizes the emission of toxic gases during a fire. This is particularly important in public buildings, industrial plants, and anywhere where the safety of people and property is a priority. The pipe works perfectly in installations exposed to moisture and most chemicals. However, it should be avoided for outdoor use, where it is exposed to direct UV radiation.

Strength and technical parameters

The pipe is characterized by high compressive strength – 750 N, which guarantees protection of cables against mechanical damage. The operating temperature range from -25°C to +110°C allows its use in a wide range of environmental conditions. The flexible construction facilitates cable routing even in difficult installation configurations. Additionally, the material exhibits high resistance to many chemical substances, which increases the durability and reliability of the installation. The pipe does not propagate flame, confirming its high level of safety.

The pipe exhibits high resistance to weak and strong acids, weak bases, and alcohols and mineral oils.

The pipe is available in sections of 50 meters in length and has an outer diameter of 25 mm and an inner diameter of 21 mm. It complies with directive 2014/35/UE (LVD), confirming its safety and quality.
