Description
The PRAGMA DN/ID 315 mm polypropylene sewer pipe is a high-strength professional solution designed for the construction of major underground sewer networks with a large drainage capacity. Manufactured by the world leader PIPE LIFE, this two-layer corrugated pipe is designed to withstand extreme loads, making it ideal for deep excavation and laying under busy transport arteries. The special polypropylene material (PPR) provides absolute inertness to chemically aggressive fluids, industrial waste and high temperature amplitudes of liquids. The structural design with a corrugated outer wall effectively distributes the stress from the earth pressure, while the perfectly smooth inner layer guarantees excellent hydraulic properties and prevents the appearance of sediments.
Thanks to its uncompromising quality and high class of annular stiffness, the PRAGMA system guarantees decades of trouble-free operation and structural stability of the network. This model is a key element in the construction of large-scale drainage projects, allowing for the smooth transportation of wastewater from large manufacturing plants, residential districts or entire urban areas. The optimized weight of the pipes facilitates manipulations on the construction site, while minimizing the costs of heavy mechanization and subsequent technical maintenance, turning the project into a safe and profitable long-term investment.
Purpose:
- Construction of main external underground sewer collectors and street networks
- Discharge of large volumes of domestic and industrial wastewater from enterprises and settlement systems
- Transportation of rainwater and construction of large-scale main drainage systems
- Laying drainage routes under areas with intense automobile and heavy truck traffic
Main advantages:
- Maximum service life of underground infrastructure without risk of corrosion or deformation
- Significantly reduced weight compared to concrete alternatives, ensuring faster and cheaper installation
- Minimal maintenance and cleaning costs thanks to the self-cleaning inner surface
- Perfect compatibility with fittings from the series to achieve 100% tightness against leaks and infiltration
Technical characteristics:
- Material: Polypropylene (PPR)
- Outer diameter (DN/OD): 315 mm
- Inner diameter (DN/ID): 277.4 mm
- Length: 6 m
- Ring stiffness: SN 10 (greater than or equal to 10 kN/m²)
