GRP sea outfall couplings

Solico developed the concept of the GRP couplings to withstand the forces during installation and to provide maintenance and leak free couplings between the HDPE pipe sections during its design life. The result is a coupling that connects the pipe sections without using any metal parts.

Why are composites used here?

Chemical/corrosion resistance
Composite materials are resistant to a lot of chemical products such as acids, hydroxides, crude oil, etc. Corrosion resistance against salt and seawater is excellent.

Cost effectiveness
Though composite materials themselves are slightly more expensive than metals, combining properties such as insulation and weight savings often results in a cost effective product.
