PP cover dn 425mm, class A15=1.5t, for corrugated riser pipe 425mm, black color (Diamir 425NW) 2569405090

Diamir manhole cover – durability and safety

The cover is made of polypropylene (PP) with a diameter of 425 mm, designed for corrugated riser pipes of the same diameter. It is intended for use in gravity sewer systems, both sanitary, stormwater, and combined. Class A15 means the cover can withstand a load of up to 1.5 tons – ensuring safety in areas exposed to pedestrian and vehicle traffic.

This cover is part of the Diamir manhole system, which offers comprehensive solutions for the construction of sewer networks and drainage. The Diamir system includes inspection chambers (non-access and access), chambers with settling tanks, and elements for building sewage pumping stations. The use of plastics in the construction of manholes and covers ensures corrosion resistance and long service life.

• Strength: Class A15 (1.5 tons) guarantees safety even in areas with high traffic.
• Chemical resistance: Polypropylene is resistant to many chemicals present in wastewater, ensuring long-term operation.
• Lightweight: Compared to concrete or cast iron covers, the PP cover is lighter, making it easier to install and remove during inspection or maintenance.
• Compatibility: Specifically designed for corrugated riser pipes with a diameter of 425 mm from the Diamir system – ensuring a tight and stable connection.
• Color: Black color increases visibility and aesthetics of the installation.

The Diamir cover is a solid and reliable solution for professionals involved in the construction and maintenance of sewer networks and for investors who value the durability and safety of installations. Its lightweight construction makes work easier for installers, and its high load resistance guarantees long-term use without frequent repairs or replacements.
