However, this connection is only a part of a device. For example, if the flange is connected to a water pump, it is not good to call the water pump a "flange part". Smaller ones such as valves can be called "flange parts". Flanges are usually welded on the circumference of the end of the pipe to connect the pipe, valve and shaft together. Due to its good comprehensive performance, flanges are widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, pipelines, fire protection, electricity, aerospace, shipbuilding and other basic projects. Flanges are also called flanges or flanges.
