Insulating monolithic joint
Insulating monolithic joint is a permanent pipeline item which provides electrical disconnecting of the pipeline sections.![Installation of the insulating monolithic jointDN 1420 mm at the gas pipeline](http://pipe-st.com/images/bodyblock/20180529-094253.jpg)
DN 1420 mm at the gas pipeline
Insulating monolithic joints are installed:
- at the border of sections with pipelines electrochemical protection;
- at the border of the property plots, including disconnecting from the lateral pipeline;
- at the borders of pipeline sections with different types and quality of protective coatings, different systems of electrochemical protection or significant change of soil electrical resistivity, including between above-ground and underground areas;
- at the ends of coverage area of stray or telluric direct currents or alternating voltage;
- at the crossings lines of multi-line pipelines with water barriers;
- at the interface line of unprotected or grounded buried structures or equipment;
- in other places where electrical disconnecting of the pipeline is required.
