What are the temperature requirements of the double flange electric ball valve when welding? The double flange electric ball valve is also called the double flange valve compensation joint. This product has the characteristics of reliable sealing. When the double flange electric ball valve starts welding, the heat conduction needs to be preheated, so wait a moment. After preheating, there will be no automatic prompt, so the electric ball valve welded with welding tools has certain error.
Although the double flange electric ball valve has temperature error during welding and can not fully control the temperature, there is a big hidden danger for the electric ball valve after welding in use. The interface between the electric ball valve and other equipment shall be welded. When the temperature cannot be controlled, errors will occur. Therefore, the connection between electric ball valve and other equipment is very weak.
In the later use, when there are corrosive substances in the pipeline transportation, the connection between the electric ball valve and other equipment is easy to cause leakage, which will affect the service time of the pipeline.
