Flange (Flange), also known as flange flanges or flange. Flanges are connected to each other between the tube and pipe parts, the connection between the pipe end for; also useful equipment import and export on the flange for connection between the two devices, such as a gear flange. Flange connection or flange joint, is defined by flanges, gaskets and bolts of the three connected to each other as a group combinations detachable connection seal structure. Pipe flange means conduit means for piping flange, with import and export flange on equipment means equipment. There are holes on the flange, so that the two flange bolts tightly connected. Between flange sealing gasket. Threaded flange points (threaded connection) flanges, welded flanges and clip flange. Flanges are used in pairs, you can use low-pressure pipe thread flange, four kilograms more than the use of a pressure welding flanges. Between the two flange gaskets, then bolted. Different flange thickness at different pressures, they use different bolts. Pumps and valves, and pipe connections at local these facilities and equipment, also made of a shape corresponding to the flange, also known as the flange connection. Any use of the surrounding bolted in two planes simultaneously closed parts, generally known as the "flange", such as ventilation pipe connections, this type of parts can be called "flange parts." But this is only a partial connection device, such as flanges and pump connection, bad water pump called "flange parts." Relatively small, such as valves, etc., can be called "flange parts." Reducer flange for connection to the motor and gearhead connection, as well as gear and other devices.
