Corrugated Pipe Fittings
Role of Dedicated Fittings in Gravity Corrugated Networks
Structured-wall corrugated polyethylene pipes feature an exterior profiled wave that demands dedicated couplers matched to corrugation valleys. Corrugated couplers and elastomeric sealing rings deliver a continuous, flexible joint between pipe lengths.
These components are direct complements to double-wall corrugated sewer pipe and perforated corrugated drainage pipe, enabling gravity sewer and civil storm runoff networks.
Coupler Standard & Component Architecture
Corrugated couplers in this series are designed in alignment with European standard EN 13476 for structured-wall piping systems. Sealing rings are molded from resilient elastomeric formulations resisting municipal sewage chemicals.
The coupler and gasket combination prevents exfiltration of sewage into groundwater while prohibiting groundwater infiltration into municipal drainage grids.
Trench Assembly & Gasket Positioning Best Practices
The sealing ring must seat cleanly and evenly within the second corrugation valley at the pipe spigot. Applying an approved lubricant onto the internal coupler surface and elastomeric ring is necessary before engagement.
Insertion should proceed strictly along the pipeline axial centerline using steady levering forces to prevent gasket displacement or fishmouthing.
