Introduction to Industrial Flange
Industrial flanges are crucial components in the piping systems used across various industries. They are flat, circular discs with holes in them to allow bolts to pass through, which are then used to connect pipes, valves, pumps, and other equipment to form a complete piping network. Flanges provide easy access for cleaning, inspection, modification, and maintenance of the piping system. They are available in different types, such as weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, and are made from a variety of materials including carbon steel, stainless steel, alloy steel, and cast iron, depending on the specific requirements of the application, such as pressure, temperature, and the nature of the fluid being transported.
Now, let's take a look at the top 10 industrial flange manufacturers in China:
