Monolithic Insulation Joints

Monolithic Insulation Joint is a boltless structure that provides electrical resistance between the pipeline sections and adjoining structures, thus improving the effectiveness of the Cathodic Protection System (CP systems).

Specifications:

* Suitable for oil, city gas, natural 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 @ 1000v DC under dry air at 25 oC

-- Dielectrical Voltage: = 3.5kv AC 50Hz (1 minute) (Can be 5kv as per request)

Ordering Information:

Please specify the following requirement:

** Pipeline Diameter, Grade of Pipe, Wall Thickness of Pipe;

** ANSI Rating

** Medium to be transported in pipeline and temperature of transported medium
