Double-layer corrugated polypropylene pipes are designated for laying sewage, storm and ground waters. These pipes with versatile construction are practically used in all areas in industry, hydraulic engineering, hydrological systems, in the construction of railway and motor roads. Unlike other pipes, corrugated double-layer pipes with socket have the following advantages:

• Quick and easy installation due to socket
• Possibility of cabling under roads with a large dynamic load
• These pipes do not carry much weight, but they have greater endurance due to their rings that meet the standards (8 KN/m2 or SN8)
• Due to their smooth inner surface, different impurities and sediments are not assimilated inside the pipes.
• Able to withstand to **5ºC water temperature in limited time.

Double-layer corrugated polypropylene pipes are manufactured with the help of up-to-date German equipment and applying extrusion molding method. Inner surface is smooth and external surface is corrugated. External layer is painted in black, which protects the material from ultraviolet ray. Internal layer is painted in yellow or white. Operating life of these pipes is over *0 years.
Quality control of propylene pipes is exercised in accredited AZS ISO/IEC ****5:***9 quality standard laboratory.
