CorPress™ Mechanical Joint for Corrugated Pipes

CorPress™ is a high-performance double-shell mechanical joint designed to provide secure, watertight connections for corrugated polyethylene (PE) and polypropylene (PP) pipes. Engineered for demanding drainage and sewerage applications, the system combines exceptional sealing performance with enhanced pull-out resistance, making it suitable for both standard installations and more challenging environments.

The external shell is manufactured from durable polypropylene (PP), while the internal lining is formed from a specially profiled thermoplastic elastomer (TPE). The TPE lining is designed to match the corrugated profile of the pipe, creating a continuous, high-integrity seal across the entire external surface and delivering superior hydraulic performance compared with conventional connection systems.

Description

The two shells are assembled on site using stainless steel bolts and screws, which are tightened in accordance with the manufacturer’s installation instructions to ensure a secure and reliable connection.

Compatibility Note:
The profiled TPE sealing surface has been specifically designed for corrugated pipes manufactured by the System Group companies referenced in the original product specification. Sealing performance cannot be guaranteed when used with corrugated pipes produced by other manufacturers.

Features & Benefits

  • Exceptional Sealing Performance
    The profiled TPE inner lining conforms precisely to the corrugated pipe profile, providing a highly reliable, watertight connection.
  • Enhanced Pull-Out Resistance
    The mechanical joint design improves resistance to pipe separation, making it ideal for applications where additional joint security is required.
  • Simple Installation
    Designed for straightforward on-site assembly using stainless steel bolts and screws, reducing installation time while ensuring consistent performance.
  • Ideal for Repair Applications
    Can be used to create effective repair solutions for existing corrugated pipe networks, helping to minimise disruption and extend system life.
  • Suitable for Challenging Installations
    Well suited to vertical installations, bridge structures, viaducts and other applications where conventional jointing methods may be unsuitable.
  • High Impact Resistance
    Robust construction provides excellent resistance to mechanical impact, helping to maintain joint integrity during installation and throughout the operational life of the network.
  • Durable Materials
    Manufactured from high-quality polypropylene (PP), thermoplastic elastomer (TPE) and stainless steel components to ensure long-term reliability in demanding environments.
