Dual containment (also called secondary containment), are specialised piping systems designed to provide a maximum level of safety and protection from hazardous liquids and materials, that could potentially be dangerous to people or the environment.
The outer layer of piping is designed to protect the inner pipe from any damage and to protect the environment in the unlikely event of any leaks on the inner carrier pipe. Visual and automatic leak detection options are also available to suit.
This system comes in PP/PP or PE/PE and is joined in a simultaneous welding process making it easy and quick to install.
