Johnson Screens Di-Electric Coupling

Johnson Screens' Di-Electric couplings prevent galvanic corrosion in municipal and industrial water well completions.

Insights

When two dissimilar metals are coupled in water-saturated environments, the less corrosion-resistant metal corrodes faster from the galvanic cell created. This corrosion can be prevented by eliminating the contact between the two metal surfaces.

A true Di-Electric coupling uses non-conducting insulating ring material to isolate the metal surfaces and prevent electrical contact. This feature increases the life of the pipe and the life of the well.

Johnson Screens' Di-Electric couplings are available for pipe sizes from 1.5 - 24 in. Special sizes or connection adapters are available on request.

    Advantages, Features and Benefits

    • In the center of the coupling, an insulating sleeve prevents dissimilar metals from making contact and causing corrosion of the casing. This feature extends the life of the pipe for long-term savings.
    • The coupling has a small OD, only 1.5 to 2 in. larger than the pipe. This feature saves costs by minimizing the size of the hole to be drilled.
    • The nominal ID of the string is maintained through the coupling for full design functionality.
