INTRODUCING THE NEW CORMA SUPER COUPLING
Following Corma’s patented single layer in-line coupling in 1985 and then the double layer regular and bell & spigot in-line couplings, Corma is introducing the brand new Corma Super Coupling (Patent Pending) as an innovative and cost effective solution that significantly increases the effectiveness of the pipe’s seal.
Spigot End
Extended Sleeve
ADVANTAGES Extended sleeve creates a robust seal between the pipe layers within the coupling.
During event such as earthquakes, high traffic loads or imperfect installations that cause movements in the soil, the Corma Super Coupling (Patent Pending) is capable of maintaining a full seal due to the increased overlap.
In contrast, the overlaps on single layer couplings are too short, so the seal is compromised when there are movements in the soil. This can cause a void between the pipe layers and allow debris to accumulate.
Manufactured in-line on Corma corrugated plastic pipe production lines without the need of belling machines
