![]() There are many factors that affect the performance of a flange, but they need to be taken into consideration in order to achieve the best performance.

It is an alloy of zinc and copper, often containing tin or lead as well. Cast iron has many properties, such as machinability, castability, and fluidity. #5 Cast IronĬast iron is made when the iron is alloyed with silicon, carbon, and many other alloys. ![]() This is important during flange manufacturing which requires low weight and strength. It has better corrosion resistance properties than any other special alloy steel. #4 AluminumĪluminum provides a low-density, ductile and malleable metal with moderate strength. This chromium property enables stainless steel to have a higher corrosion resistance than carbon steel which rusts easily from exposure to air and moisture. ![]() Stainless steel contains chromium in excess of 10%. Common alloy steels are chromium, molybdenum, nickel, and manganese. Metallurgy refers to alloying steel with elements that alter or enhance its properties. It offers high strength and hardness, increased carbon content, low melting point, and ductility. It is a type of steel alloy that contains carbon. The following are common materials used to make flanges: #1 Carbon Steel Factors such as economy, flow pressure, operating temperature, and environmental corrosion are considered when selecting a flange for a particular application.

Using these flanges, equipment and valves protect against excessive stresses that can arise due to line temperature and pressure. The purpose of these types of flanges is to restrain or limit main line thermal expansion and contraction, as well as to transfer built-up stress to external structures or a larger foundation. Typically, after the flange has been welded to the pipe, it is anchored to a concrete foundation.

Here is a simple guide to the most common and popular types of flanges and their uses. With so many varieties and specifications, it may not be easy to identify which one is right for your need. In a piping application, the type of flange to be used depends largely on the strength requirements.įlanges come in many different shapes and sizes and are used in a wide range of industries around the world. The flange can withstand high pressure and temperature, so they have different pressure and temperature ratings for different materials. Common standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). ![]() Many different flange standards are found worldwide to allow easy functionality and interchangeability. It is usually welded or threaded, and the two flanges are joined together by bolting them with gaskets to provide a seal, providing easy access to the piping system. Flanges are devices used to connect pipes to each other, to valves, to pumps, to fittings, and to other equipment such as filters and pressure vessels.
