What Is A Plumbing Dielectric Union ?
 |
Certain plumbing requirements may ask you to join an iron pipe to a copper pipe. Some homeowners don’t accept the fact easily that the one kind of pipes can be connected to another kind of pipes in the same plumbing architecture. However, such modification can be achieved easily with the help of specialized plumbing components. Though the job of joining an iron pipe to a copper pipe is similar to the installation of copper fittings, it requires certain additional components as well.
A dielectric union is one such component that is used at the juncture of copper pipe and iron pipe.
A dielectric union consists of two halves. While the first half handles the iron pipe, the second half contacts the copper pipe. The union acts as a boundary between the two types of plumbing pipes such that no structural imbalance is encountered. Without the dielectric component, the two pipes may not be able to complement each other during the normal proceedings.
Before installing the dielectric union, you need to braze the participating ends of the two pipes. With the help of a fitting brush, start brazing the inner sides as well as the outer surface of the copper pipe. The brazing operation would eliminate all the foreign objects that could pose a problem to the efficiency of the upcoming joining operation.
Use the fitting brush to braze the insides of the copper pipe as well. Restrict the application to the portions of the pipe that would take part in the upcoming connection. Next, use a flux brush to apply flux solution to the brazed surfaces of the copper pipe.
Initiate the actual task of installing the dielectric union component in between the two pipes. To do so, unscrew the dielectric union such that it dissociates into two equal halves. While one half of the union is installed on the iron pipe, the other part deals with the copper pipe segment. Install the copper-half first by sliding the segment on the pipe length.
Solder the juncture using a solder and a heating torch. The solder melts down and joins the dielectric union to the face of the copper pipe. Follow the same procedure to install the other half on the iron pipe. Redo the screws on the dielectric union to finish off the proceedings.
Avail the assistance of an expert if you face any complication in the project.
