Business Type: Manufacturer
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.
