External PVC drainage pipe 200x4.9x2000 SN4 Class N ML (multilayer, foamed), with K-U21 LOCK type seal. 0425213200

External PVC drainage pipe – reliability and durability in wastewater drainage system

PVC pipe with a diameter of 200 mm, wall thickness of 4.9 mm and length of 2000 mm, designed for the construction of external, non-pressure sewage systems. Made of foamed polyvinyl chloride (PVC) (multilayer technology – ML), it is characterized by high mechanical strength and resistance to loads. Stiffness class SN4 ensures the stability of the structure even in difficult ground conditions. The product of the Kaczmarek brand, with catalog number 0425213200, is a proven element of sewage installations.

Construction and application

The pipe is designed for use in underground drainage and sewage systems, both in road lanes (under or outside the roadway) and in other areas used for communication purposes. It will also be useful as a cover for other pipes and culverts through road embankments or drainage of bridge structures. The version with an extended socket is particularly recommended in areas exposed to mining damage. Thanks to the smooth inner surface, flow resistance is minimized, which reduces the deposition of contaminants and facilitates maintaining the system's patency.

Advantages and benefits for professionals and users

• Strength and safety: Stiffness class SN4 guarantees resistance to operational and ground loads, ensuring the long-term reliability of the installation.
• Lightweight and easy installation: Multilayer (ML) technology with a foamed layer reduces the weight of the pipe, making it easier to transport and install. The LOCK system ensures tight and quick connections without the need for additional seals (recommended according to the installation instructions).
• Chemical resistance: The foamed PVC material is resistant to the action of chemicals present in wastewater, extending the life of the system.
• Optimal length: A length of 2 meters facilitates transport, storage and adaptation to specific installation needs.
• Versatility: The pipe is suitable for use in residential, industrial and municipal construction.
• Reduced operating costs: The smooth inner surface minimizes the deposition of contaminants, reducing the frequency of cleaning and maintenance of the sewage system.

This pipe is a solid solution for both professional installers looking for a reliable material for building sewage networks and for end users who value durability and trouble-free operation of the wastewater drainage system.
