ASME B16.5 Flange Dimensions and Weight/ Pressure Class 150 To 2500

Searching For ANSI B16.5 Flange manufacturer For Custom Size? Industrial Flanges supplier in Mumbai, India

ASME stands for the American Society for Mechanical Engineers that has laid down standards for manufacturing various products. They have set standards for manufacturing different grades of products. ASME Flange is one such product that is manufactured as per these specifications. This specification is divided into several grades. One such type is the ASME B16.5 Flange. As per this specification, these B16 5 Flanges are made up of cast, or forged material whereas blind flanges are made up of cast, forged, or plate material. This standard also consists of recommendations regarding flange gasket, flange bolting, and joints.

As per ASME B16 5 Flange Dimensions minimum wall or flange thickness, permissible material for construction, and work stress allowed are mentioned in this standard. Flange ASME B16 5 provides for pressure integrity standard that helps in providing minimum uniform performance criteria, and a dimensional standard that helps in monitoring and controlling the parameter of the component. Flange ANSI B16 5 can be pressure rated depending upon a 3 step process. The first is to determine the material to be used for manufacturing. The second is to determine the maximum temperature and operating pressure. Third and the last is to refer to the correct ANSI Flange Standard table.

D Table Flange is often confused with a standard. However, it is the table that denotes the pressure rating of the flanges that belong to a particular standard. In this case the BS 10 of the British standard institute. ASA 150 Flange is said to be the most commonly used standard pipe gasket size. They can be manufactured as full face gaskets or IBC gaskets. It has a pipe size ranging between 1 inch to 12 inches in diameter. High Pressure Pipe Flange needs to meet top quality standards and require to be leak free. ANSI B16.5 Flanges are widely used in refinery, power generation, petrochemical, energy, and oil and gas industry.
