Flanges come in many types, categorized by shape, function, material, etc. Common flange fittings include flange elbows, flange tees, flange crosses, flange reducers, and flange blanks. Each type has specific uses and advantages.
Flange elbows: Used to change the direction of a pipeline; common angles are 45, 90, and 180 degrees.
Flange tees: Used to connect three pipelines, enabling branching or merging.
Flange crosses: Similar to tees but with four connections, used to connect four pipelines.
Flange reducers: Used to connect pipelines of different diameters, ensuring a smooth transition.
Flange blanks: Used to temporarily seal one end of a pipeline for maintenance or inspection.
