What is the welding flange valve, is it the flange and pipe welding, and then the valve flange with bolts on the pipe connected to the flange? What is the threaded flange valve?
2 、 heating the solder with lower melting point independently, without melting the workpiece itself, and connecting the workpiece with the capillary action of the solder (such as soldering and brazing);3, in the equivalent or lower than the melting point of the workpiece temperature, with high pressure, folding, extrusion or vibration, so that the two pieces of mutual penetration between joints (such as forging welding, solid-state welding).According to the specific welding process, welding can be divided into welding, resistance welding, arc welding, induction welding and laser welding and other special welding.
A welded flange valve is a valve installed on a pipe to weld flanges.Welding: welding, also known as the melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology. To achieve the purpose of joining by welding in the following three ways:1. Heating the workpiece to be melted locally to form a molten bath. The bath is cooled and then joined. If necessary, the melt can be added to the melt;
The valve is the valve flange welding flange welding flange installed in the pipeline, the valve is threaded flange threaded flange installed in the pipe threading to install the valve, but no difference for the valves, pipeline installation flange just not in the same way.
