Export Flanges

Flange, also known as a flange disc or rim, is a component used for connecting shafts or for joining pipe ends; it is also used on equipment for connections between two devices, such as a reducer flange. A flange connection or flange joint refers to a removable joint made up of the flange, gasket, and bolt, which together form a sealing assembly. Pipe flanges are the flanges used for piping in pipe installations, and on equipment, they refer to the equipment's inlet and outlet flanges. Flanges have holes and bolts are used to tightly secure them together. They are sealed with a gasket. Flanges are available in threaded (screwed) connections, welding flanges, and clamp flanges. Flanges are used in pairs; low-pressure pipelines can use threaded flanges, while those above 4 kg of pressure require welding flanges. A sealing gasket is placed between the two flange disks, and then secured with bolts. Flanges of different pressures have different thicknesses and require different bolts. In the case of pumps and valves, when connected to pipelines, the local parts of these equipment items are also made in the shape of corresponding flanges, also known as flange connections. Any connection piece that uses bolts to connect two flat surfaces around the circumference and is sealed is generally called a "flange," such as the connection of ventilation pipes. Such parts can be referred to as "flange-type parts." However, this type of connection is only a local part of a device, such as the connection between a flange and a pump, so it is not appropriate to call the pump a "flange-type part." Smaller items like valves can be called "flange-type parts."
