Monolithic Insulating Joints
Cathodic Protection - Weld Ends - Threaded Ends - Flange Ends
CP Isolation joints are used to electrically isolate pipelines.
Pipeline Monolithic Isolation joints, provide Cathodic Protection. CP joints electrically "split-up" long pipelines and branch lines into distinctive cathodic protection systems.
Westatlantic class protection for all pipe diameters, standard ISO 3183-API 5L - and other specified pipe grades are available.

Monolithic Joints are coated to prevent corrosion and are 100% tested hydrostatically, electrically and for weld performance.
Monolithic Joints provide electrical sectioning and passive protection against corrosion, they are installed in inlet and outlet pipes, on meters, tanks, pumping station, etc.
Monolithic Isolating Joints do not require maintenance, and they improve the cathodic protection of gas, water and petroleum pipelines with important savings in operation and maintenance cost.
Depending on the specification, monolithic isolation joints may be a stock item or built to spec for specific applications:
