"NIK-SAN" MONOLITHIC INSULATING JOINTS:

Insulating Joints are used on pipelines to provide electrical isolation to prevent corrosion. They provide current spreading on cathodic protection systems. They provide electrical separation between pipeline section and the adjoining neighbouring structures and pipelines. Wherever practical, the NSE insulating joint is intended to be installed above the ground, or in an inspection pit in dry conditions to limit the possibility of electrical bridging across the joint. It is intended to be girth welded between two pipeline sections.


BENEFITS & ADVANTAGES:

• No loss of integrity due to thermal expansion or ground stress as is common with flange isolation gasket kits.
• In-factory tested hydrostatically and electrically, to 1.5 times their working pressure. Non-destructive testing is also available.
• Maintenance-free, reliable cathodic isolation of equipment in required isolation applications such as compressor stations.
• No labor intensive, complicated installation procedure required as is the case with isolation gasket kits,
• No inspection pits, vaults or maintenance needed - weld into place and direct bury - reliable, worry-free cathodic isolation.
• Non-conductive epoxy coatings help prevent shorts, both internally and externally.
• Isolation stray currents impressed on the pipe from exterior forces such as electrical transmission systems, earth currents and currents flowing from point to point.
• Excellent bending and torsional resistance.
• Earthquake resistant - acts as a thrust block or joint.

Monolithic insulating joints (or isolation joints) provide just such protection. Specially designed to be shock absorbent and insulated against electrical charge, they isolate sections of pipeline so that currents can only pass so far. Materials placed within the monolithic isolation joint also work by attracting electrical charge and preventing corrosion. This is achieved by something called cathode protection - where the material in the joint becomes an anode, and the pipeline becomes a cathode. The anode protects the pipeline from corrosion. You can see the same devices attached to ships, while they are also installed in concrete constructions and on bridges as well. Without them, complex engineering would be extremely difficult.

The advantages of using the monolithic isolation joint is that this kind of joint avoids small parts such as gaskets and flanges, and can be produced to exacting standards of precision. They can be ordered in whatever pipe size is required, and sealed easily and safely without the need for welding. They can also be delivered to clients pre-tested and produced to the specifications of the client, avoiding the need for technicians to attend to the installation process.

A monolithic isolation joint is a factory-assembled, fully welded component used in pipelines to provide electrical isolation between sections. It's designed to prevent the flow of electrical currents, particularly stray DC currents, which can cause corrosion. This isolation helps protect the pipeline from corrosion, especially in areas with varying soil resistivities or when connected to structures with dissimilar metals.
