eristysliitoksia

Eristysliitoksia, commonly translated as insulating joints or dielectric unions, are essential components in piping systems. Their primary function is to prevent the flow of electrical current between different sections of a pipe. This is crucial in applications where dissimilar metals are used in the piping, as it can lead to galvanic corrosion. By introducing an insulating material, typically a non-conductive polymer or composite, between the metal components, eristysliitoksia effectively breaks the electrical circuit.

These joints are widely used in plumbing systems, particularly in water supply lines where copper pipes might connect to steel or other metals. This prevents stray electrical currents, often originating from the electrical grounding system of a building or from electrochemical reactions within the water itself, from causing damage. In gas piping, eristysliitoksia serve a similar purpose, preventing electrical arcing which could ignite flammable gases.

The construction of an eristysliitos typically involves two threaded metal ends separated by a central body made of insulating material. A gasket or seal is incorporated to ensure a watertight or gas-tight connection. The selection of the appropriate insulating material depends on factors such as operating temperature, pressure, and the type of fluid or gas being transported. Proper installation is vital to maintain the integrity of the electrical insulation and the mechanical strength of the joint.
