Concrete tapered socket dn 425mm, class B125=12.5t, for corrugated pipe 425 (Diamir 425NW) 2951162000

Concrete cone for Diamir 425NW manholes.

This reinforced concrete cone is designed for the construction and completion of Diamir 425NW manholes. It is a key element in creating a functional and durable underground infrastructure for sanitary, stormwater, and drainage systems. The cone provides a tight connection with a corrugated pipe with a diameter of 425 mm, enabling efficient water and wastewater drainage.

Construction and application

Made of reinforced concrete, the cone is characterized by high resistance to loads and corrosion. Concrete class B125 (12.5t) guarantees adequate load-bearing capacity, which is important for loads occurring in pedestrian and bicycle traffic – according to A15 classification. The cone is primarily used as a finishing element for non-manhole and manhole inspection chambers, as well as in wells with settlers used in stormwater and drainage systems. Thanks to its design, it allows easy access to the sewer network for inspection or maintenance.

Advantages and benefits

• Durability and strength: The reinforced concrete construction ensures long-term operation even in harsh environmental conditions.
• Tight connection: Precise fit to the Diamir 425NW corrugated pipe guarantees a tight connection, minimizing the risk of leaks.
• Load resistance: Class B125 provides adequate load-bearing capacity for pedestrian and bicycle traffic.
• Easy installation: The cone is easy to install, which translates into saving time and costs during the construction or modernization of the sewer network.
• Compatibility: Designed specifically for use with Diamir 425NW corrugated pipes, ensuring a perfect fit and functionality.
• Versatility: Can be used in various types of sewer networks – sanitary, stormwater, combined, and drainage.

Additional information: The weight of a single cone is approximately 75.4 kg and its dimensions are 0.72 x 0.72 x 0.22 m. The cone is manufactured by Kaczmarek, a well-known manufacturer of sewer infrastructure elements.
