Importance and types of metal flangesUntitled part

Metal flanges are mechanical parts that join two or more elements of a piping system, be they valves, pumps, or other pipes. The method of tightening flanges is due to the perforated neck where bolts are placed in radial sequence so that a leak-free coupling is achieved. For this reason, it is also called a perforated metal flange or, in smaller sizes, screw metal flanges.
