Flanges are mechanical components used to connect pipes, valves, pumps, and other equipment in fluid and pipe systems. They are typically made from materials such as carbon steel, stainless steel, or plastic, and are designed to create a tight seal to prevent leaks. Flanges come in various shapes and sizes, allowing for versatile applications in different piping systems.
| Material | Carbon steel, stainless steel, or plastic |
| Standard sizes | 1/2 inch to 48 inches |
| Pressure ratings | 150 to 2500 psi |
| Face type | Flat face, raised face, or ring type |
| Bolt hole pattern | Varies by size and type, typically ANSI or DIN standards |
When selecting flanges, consider the material compatibility with the fluids being transported, as well as the pressure and temperature ratings required for your application. Specify the size, face type, and any relevant standards such as ANSI or DIN. It's also important to determine the quantity needed and whether any specific certifications are required for your industry.
