Why Global Contractors Choose Our HDPE Pipes
Withstands aggressive soil chemistries (pH 2–12) and municipal biogenic H2S gas corrosion.
Extruded strictly from high-grade virgin HDPE, ensuring long-term molecular stability. Delivers a 50+ year service life under proper EN 1610 / ASTM D2321 backfill guidelines.
Significantly lighter than concrete or ductile iron alternatives. Reduces heavy-equipment dependency (fewer cranes needed) and accelerates daily trench-laying cycles.
What the Double-Wall Structure Delivers
Corrugated Outer Wall - Structural Support
The corrugated outer wall increases ring stiffness while maintaining an efficient pipe structure. Available SN4 to SN16 stiffness grades allow buyers to select suitable options according to burial depth, soil conditions and project loading requirements.
Smooth Inner Wall - Efficient Flow Surface
The smooth inner wall provides a continuous flow path for drainage and sewer applications, helping improve hydraulic performance and reduce flow resistance. This design is suitable for gravity drainage systems where consistent water flow is required.
Choose the Ring Stiffness According to the Project
|
Ring Stiffness |
Typical Procurement Consideration |
|
SN4 |
Suitable for project conditions where a lower stiffness class meets the design requirements |
|
SN8 |
A commonly specified stiffness level for many buried drainage applications |
|
SN12.5 |
Considered where project design calls for a higher stiffness class |
|
SN16 |
Available for applications requiring a higher specified ring stiffness |
Connection System & Supporting Components
Socket & Spigot Joint with Rubber Sealing Ring
The socket and spigot connection uses elastic rubber sealing rings to provide a secure joint between pipe sections. The flexible sealing design helps accommodate normal installation conditions and ground movement when installed according to project requirements.
Couplings & Custom Connection Options
Couplings and other connection solutions can be supplied for specific project layouts, customized pipe lengths or special installation requirements. Available options depend on pipe diameter, connection design and application conditions.
Available Accessories
- Elastic rubber sealing rings
- Couplings
- Elbows
- Tees
- Plastic inspection wells
- End caps
