The middle bead of the Galvanized Union bead is made inside the thread of the material, and the other two parts that are threaded from the thread are attached to the middle bead in a screw, and the two ends of the galvanized thread of the thread are connected from the inside. The screw is connected to the desired line and it is very easy to install and open, and this has caused a lot of consumption of this part of the galvanized connections.
