Outer Casing Joints
Below, we have detailed the current range of options available for the outer casing joints, which include tubular joints that are fitted prior to the jointing of the service pipes and wrap-around systems that can be fitted after the service pipes are joined – including scenarios where repairs are required to damaged casings on live networks.

Suitable for all types of Hiline systems, including flexible corrugated casings.
Clam-Shell Joints
These are suitable for the three Hiline PEX-based flexible systems with corrugated casings.
