Description
Technical Field

Background
A flange, also known as a flange collar or flange. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flanges are used in pairs, the low-pressure pipeline can use threaded flanges, and the flanges are welded under the pressure of more than four kilograms. And a sealing gasket is arranged between the two flanges and then is fastened by bolts. The flanges of different pressures have different thicknesses and they use different bolts. When the water pump and the valve are connected with a pipeline, the parts of the equipment and equipment are also made into corresponding flange shapes, which are also called flange connection. The connecting parts which are connected by using bolts at the peripheries of two planes and are closed at the same time are generally called flanges, and for example, the connecting parts of the ventilating duct can be called flange parts. However, the connection is only a part of equipment, such as the connection between a flange and a water pump, and the water pump is not easy to be called as a flange part. The valve is relatively small, such as a valve and the like, and can be called as a flange part.
