Thank you. I've read that corrosion of steel pipe( the anode) is not an issue when it is relatively large compared to the size of the copper cathode. But in our case, we've electrically isolated the steel pipe in the system from the copper pipe. So the anode (instead of being the entire...
We purchased dielectric unions to help avoid galvanic corrosion between a copper nipple and steel pipe. Problem is, the unions are steel on both sides of the isolator. So now we have a copper nipple threaded to the steel union. Are there different uses of dielectric unions? Or are we using...
We have a situation where a copper HVAC coil headder is connected to a copper nipple which is then connected to a "dielectric union". On the other side of the dielectric union is steel piping. The dielectric union was specified in order to avoid Galvanic corrosion. Unfortunately, both sides...
