Super Coupling – An Evolution of Corma’s Coupling Technology

Corma’s Super Coupling continues a long history of innovation in coupling technology. We first developed and patented the single layer inline coupling in 1985, which led to our patented designs for both the regular and bell & spigot double layer inline couplings.

In 2016, Corma developed the Super Coupling (patent pending) as an innovative and cost-effective solution that significantly increases the effectiveness of the pipe’s seal.

How it works

The Corma Super Coupling uses an extended sleeve to create an even more robust seal between the pipe layers within the coupling. It’s designed to maintain a full seal even during events such as earthquakes, high traffic loads and imperfect installation that cause movements in the soil.

In a situation where the pipe is partially inserted into the coupling, the extended sleeve of the Super Coupling maintains a full seal, reducing the chance of obstructions and maintains the strength and integrity of the joint. In contrast, the overlap on many other couplings on the market are too short and compromise the seal when there are movements in the soil or if the coupling is shifted during installation.  This can cause a void between the pipe layers and allow debris to accumulate.

As an evolution of Corma’s in-line coupling production capabilities, the Super Coupling can also be manufactured inline on Corma corrugated plastic pipe production lines.  This significantly increases productivity and decreases cost since no downstream belling machines are required. Only one sealing ring is needed for the pipe connection to form water tight joints.

Available configurations

The Super Coupling will be available in the following configurations:
