Introduction to Metal Pipe Flange
Metal pipe flanges are crucial components in piping systems. They are flat, circular discs with holes drilled around the perimeter for bolts. Flanges are used to connect pipes, valves, pumps, and other equipment to form a complete piping network. They provide easy access for cleaning, inspection, and modification of the system. Metal pipe flanges are made from various materials such as carbon steel, stainless steel, alloy steel, and cast iron, each offering different levels of strength, corrosion resistance, and durability to suit different applications in industries like oil and gas, chemical, power generation, and water treatment.
