Flanges are essential components in pipeline engineering. They are typically disk-shaped and used in pairs to connect pipelines to valves or other equipment. Wire connection flanges are suitable for low pressure pipes, while welding flanges can handle pressure greater than four kilograms. A gasket is placed between the two flanges, and bolts are used to secure them tightly. Flanges of different pressures have different thicknesses and require different bolts.
In addition to pipeline connections, flanges can also be used to connect local equipment such as water pumps and valves to the pipeline. These flanges are designed to match the shape of the equipment they are connecting to. Any parts that are bolted together in two planes and closed at the same time can be considered flanges, such as the connection of ventilation pipes. However, it is not appropriate to refer to equipment such as pumps as "flange parts", even if they have flanges. Smaller equipment like valves can be referred to as "flange parts".
