Monolithic Insulating joint (Isolating joint)

 

Introduction:

Monolithic Insulating joint (Isolating Joint) is the key component in Cathodic Protection (CP) System. It is mainly used in underground gas transition and distribution system including gas reducing station, each section of gas transition and distribution pipeline, also the part between gas reducing station and the pipeline, which increase the life of the plant and equipment by reducing or eliminating the electric and chemical corrosion damage.
