Inspection chamber PP 110 SN8 for external sewage systems 0747203300

External drainage systems made of polypropylene

We offer PP inspection chamber 110 SN8, an element of an external drainage system designed for building safe and durable wastewater drainage installations. Made of polypropylene, a material characterized by high chemical and mechanical resistance, this fitting provides a reliable connection of pipes in the sewage system. It is a key element that, combined with appropriate pipes, creates a tight and efficient underground infrastructure.

Polypropylene drainage systems are produced in a wide range of diameters – from DN/OD 110 to 800 mm – and stiffness classes, including SN 2, SN 4, SN 8, SN 12 and SN 16. Pipes and fittings in orange-brown color (RAL 8023) are characterized by a smooth inner and outer surface, which minimizes flow resistance and facilitates cleaning. Connections are made using sockets with a groove, in which a ring-shaped elastomer seal is placed, guaranteeing complete tightness.

Advantages and applications

Polypropylene exhibits high resistance to chemical compounds in a wide pH range (from 2 to 12), making it an ideal material for transporting municipal sewage, rainwater and groundwater. PP systems are resistant to corrosion and abrasion, and can also operate at temperatures up to +90°C. Therefore, the PP inspection chamber 110 SN8 is perfect for various operating conditions.

• Durability: Polypropylene ensures the longevity of the installation – even over 100 years of use.
• Tightness: Elastomer seals guarantee complete tightness of connections.
• Chemical resistance: A wide range of pH resistance makes the system versatile.
• Strength: High longitudinal stiffness and impact resistance provide resistance to mechanical loads.
• Easy installation: Socket connections facilitate quick and precise installation.

This fitting is used in both domestic, industrial and public utility installations. It is compatible with other elements of the Kaczmarek Malewo Spółka Jawna system and can be connected with smooth-walled pipes. This offers flexibility in design and adaptation to individual investment needs.

Compliance with standards and certificates

The PP inspection chamber 110 SN8 meets the requirements of PN-EN 1852-1, concerning systems of plastic pipework for underground non-pressure drainage and sewerage made of polypropylene (PP). It has national declarations of performance (DoP) and national technical assessments (KOT) issued by the Building Research Institute (ITB). Additional certificates confirm the safety of the product for people and the environment (Hygienic Certificate NIZP-PZH). This ensures that the product complies with applicable regulations and quality standards.
