Flanges are important components in piping systems and are used to connect pipes, valves, and other equipment. They are usually made of metal and are available in different shapes and sizes. Flanges are classified based on various factors, such as their shape, application, pressure rating, and material.
Here are the different classifications of flanges:
1. Shape: Flanges are available in different shapes, such as slip-on, weld neck, blind, lap joint, threaded, and socket weld. Each shape has its own unique features and is used for specific applications.
2. Application: Flanges are classified based on their application, such as for water, gas, oil, steam, and chemical pipelines. Each application requires a specific type of flange that is designed to handle the specific fluid or gas.
3. Pressure rating: Flanges are classified based on their pressure rating, which is the maximum pressure that they can withstand. The pressure rating is determined by the material and thickness of the flange. Flanges are available in different pressure ratings, such as 150, 300, 600, 900, 1500, and 2500.
