2016 | Ancillaries 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 obstruc- tions and maintains the strength and integrity of the joint. It says that 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. The Super Coupling can be manufactured in-line on


Frigel’s Heavygel air-cooled central chillers incorporate many new features


Effective seal Corma of Canada says that its Super Coupling technol- ogy is an innovative, cost effective method to improve the effectiveness of a pipe’s seal. It uses an extended sleeve to create a more robust


seal between the pipe layers within the coupling. In addi- tion, it is designed to maintain a full seal even during events such as earthquakes, high traffic loads and imperfect installation that cause movements in the soil.


Corma corrugated plastic pipe production lines. This increases productivity and decreases cost, since no downstream belling machines are required. In addition, only one sealing ring is needed for the pipe connection to form watertight joints. The Super Coupling will be available in four configura- tions: bell and spigot double layer; regular double layer; bell and spigot single layer; and, regular single layer.
