Monolithic Insulating joint
1, Pup material: API 5L Gr.B, X42, X46, X52, X56, X60, X65, X70
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.
Ø Suitable for oil, city gas, nature gas, LNG, LPG, etc.
Ø Size: 1” to 120”
Ø Matching pipeline: API 5L Gr. B, X42, X52, X60, X65, X70, etc.
Ø Pressure rating: ANSI Class 150, Class 300, Class600, Class 900, Class1500, Class2500
