Introduction:
Monolithic Insulating joint (Isolating Joint) is the keycomponent in Cathodic Protection (CP) System. It is mainly used inunderground gas transition and distribution system including gasreducing station, each section of gas transition and distributionpipeline, also the part between gas reducing station and thepipeline, which increase the life of the plant and equipment byreducing or eliminating the electric and chemical corrosiondamage.
Specifications:
* Suitable for oil, city gas, nature gas, LNG, LPG,etc.
* Size: 1 to 56
* Matching pipeline: API 5L Gr. B, X42, X52, X60, X65,X70, etc.
* Pressure rating: ANSI Class 150, Class 300,Class600, Class 900, Class1500, Class2500
* Ambient Temperature: -20oC ~60oC
* Working Temperature: -20oC ~120oC
* Standard Testing:
-- Hydrostatic test: 1.5 times MOP (Max.Operation Pressure).
-- Electrical Resistance: ≥ 20M @ 1000vDC under dry air at 25 oC
-- Dielectrical voltage: ≥ 3.5kv AC50Hz (1 minute) (Can be 5kv as per request)
