External PVC drainage pipe 160x4.0x1000 SN4 Class N ML (multilayer, foamed), with K-U21 LOCK type seal 0423213100

Durable protection for sewage and drainage systems – PVC pipe SN4

External PVC drainage pipe 160x4.0x1000 SN4 CL.N ML is a solid solution for building non-pressure systems, both in road reserves and in areas used for transport infrastructure. It will be useful for draining bridge structures, protecting cables and culverts through road embankments. Made of polyvinyl chloride (PVC), it is characterized by high resistance to mechanical damage and corrosion.

The pipe is particularly recommended for use in areas exposed to mining damage, thanks to the possibility of ordering a version with an extended socket. The multi-layer (ML) construction and foamed wall structure ensure lightness while maintaining adequate ring stiffness (SN4). This makes installation easier and the pipe better withstands external loads. In addition, the factory-mounted K-U21 LOCK-type gasket guarantees the tightness of connections and minimizes the risk of leaks.

Construction features and application

These pipes are ideal for both professional installers and end customers carrying out drainage projects. Their versatility results from the wide range of available diameters, lengths and ring stiffnesses. The use of high-quality PVC ensures long-term operation without the need for frequent replacement of elements. The orange color makes it easier to identify the pipe during installation work and in the event of the need to locate damage in the future.

• Strength: Stiffness class SN4 provides resistance to external loads typical of underground installations.
• Tightness: LOCK-type gasket locked in the socket minimizes the risk of leaks and ensures a durable connection of elements.
• Lightweight: Multi-layer construction of foamed PVC makes it easier to transport and install the pipe.
• Versatility: Possibility of use in various ground conditions, including in mining areas (version with extended socket).
• Resistance: PVC material is resistant to the action of chemical substances present in wastewater and biological corrosion.
• Compatibility: Kaczmarek pipes are compatible with other elements of the drainage system from the same manufacturer.

A pipe with an outer diameter of 160 mm and a wall thickness of 4 mm is a proven choice for building durable and reliable drainage systems that meet the requirements of standards and building regulations.
