Series Kaczmarek - DIAMIR DN/ID 400K (KORUGOWANA)
Kaczmarek - DIAMIR DN/ID 400K (KORUGOWANA)
This series is built for reliable external sewerage networks. The DIAMIR DN/ID 400K line features orange corrugated polypropylene (PP) riser pipes designed for straightforward trench installation. With a standard ring stiffness of SN4, these pipes handle soil loads and traffic pressure without extra reinforcement. The bell-less design speeds up joining, while the corrugated outer wall provides strength and flexibility.
Pipe Range and Wall Structure
Installers can choose between single-wall and double-wall corrugated pipes in 2000, 3000, and 6000 mm lengths. Both versions keep the same 400 mm internal diameter for consistent flow. The single-wall option is lightweight and cost-effective for shallow trenches, while the double-wall version adds an extra layer of durability for deeper burial or heavier traffic zones. All pipes are made from high-quality PP, resisting chemicals and root intrusion.
Kineta Inlet Fittings and Connections
The Kineta PP inlet fittings make branch connections fast and leak-free. Available in multiple sizes (160, 200, 250, 300, 315, 400 mm) and angles (135°, 180°, 225°), they fit both smooth and corrugated incoming pipes. Some models come pre-fitted with seals for quick insertion, while others are designed for direct coupling with K2 corrugated pipes. Left, right, and combined inlet types allow flexible layout planning without custom cutting.
Covers, Seals, and Accessories
Complete your manhole setup with matching covers and seals. Choose a lightweight PP cover (Class A15) for pedestrian areas, a reinforced concrete cover (Class B125) for light traffic, or a heavy-duty cast iron manhole (Class D400) with a telescopic PVC riser for roads. External and internal seals ensure watertight joints between pipes, Kineta fittings, and covers. The PP adapter sleeve (400x315 mm) simplifies transitions between different pipe diameters.
Why Choose This System for External Sewerage
This series is engineered for speed, durability, and ease of use on site. The standardized 400 mm diameter, SN4 stiffness, and bell-less coupling reduce installation time and labor costs. Orange color coding improves visibility during trench work, while the PP material guarantees long-term resistance to corrosion and abrasion. Whether you are laying new sewer lines or upgrading existing networks, Kaczmarek DIAMIR 400K delivers a complete, installer-friendly solution.
