Slip-on Flange Weld Ring

Flange, also known as a flange disk or raised rim. A flange is a component that connects shafts to each other and is used for connecting pipe ends; there are also flanges used on equipment inlets and outlets for connecting two devices, such as a reducer flange. Flange connection or flange joint refers to a removable connection made up of a flange, a gasket, and bolts as a combination seal structure. Pipe flanges refer to the flanges used in piping installations, and on equipment, they refer to the equipment's inlet and outlet flanges. Flanges have holes, and bolts secure the two flanges together. Flanges are sealed with a gasket. Flanges are categorized into threaded connection flanges (screwed flanges),焊接 flanges, and clamp flanges. Flanges are always used in pairs; low-pressure pipelines can use threaded flanges, while pipelines over four kilograms of pressure use焊接 flanges. Two flange disks are joined with a sealing gasket and then fastened with bolts. Flanges of different pressures have different thicknesses and require different bolts. Pumps and valves, when connected to pipelines, have locally shaped flanges that correspond to these equipment components, also known as flange joints. Any connection component that uses bolts to connect two flat surfaces around the perimeter and is sealed is generally called a "flange," such as the connection of ventilation pipes, which can be referred to as "flange-like components." However, this type of connection is only a local part of a device, like the connection between a flange and a pump, so it's not appropriate to call the pump a "flange-like component." Smaller items like valves can be called "flange-like components."
