PPHM KONTI KAN SEWAGE PIPE
ENGINEERED FOR EXCELLENCE
PP (Polypropylene) double-wall corrugated pipes are widely used for drainage, sewage, and stormwater management systems due to their excellent material properties and structural design. Common international standards for PP double-wall corrugated pipes include:
- EN 13476-1 and EN 13476-3: Production standard for structured-wall plastic pipes.
- ISO 21138: Specifications for non-pressure drainage and sewerage systems.
- ASTM F2736/F2764: Standards for polypropylene corrugated pipes.
PP HM Pipes
PP double-wall corrugated pipes are an excellent choice for heavy-duty sewage and drainage systems, offering superior durability, chemical resistance, and hydraulic efficiency.
Material Properties:
- Polypropylene (PP)
- High strength-to-weight ratio.
- Greater chemical and thermal resistance compared to HDPE.
- Excellent resistance to abrasion, making it ideal for sewage applications.
- More rigid and durable in higher temperatures than HDPE.
Application
- Municipal and industrial wastewater systems.
- Stormwater, rainwater harvesting, and subsoil drainage.
- Road and rail infrastructure, as culverts and drainage pipes.
Characteristics:
- Strong corrugated structure for deep burial or heavy traffic loads.
- Smooth inner wall ensures low resistance to flow, improving hydraulic performance.
- High stiffness ratings (SN 4, SN 6, SN 8, 10;12 ;16)
- Dimension range: DN/ID 100-1200mm
- Color: Outer black with inner light grey
- Manning’s coefficient is typically 0.009, which minimizes clogging and sediment buildup.
- Designed to handle high flow rates in drainage and sewage systems.
- UV-stabilized for applications exposed to sunlight.
- Typically exceeds 50 years under normal operating conditions.
- Can operate between -20°C and +90°C, with short-term resistance to higher temperatures.
- Fully recyclable, making it an eco-friendly option.
