What is the flange of the embossed cover device
Different pressure flanges have different thickness and different bolts. Water pumps and valves, when connected to pipes, are locally made of these devices, also known as flanges, also known as flanges. Where there are two surfaces in the surrounding use of bolt connection closed connection parts at the same time, generally referred to as the "flange", such as ventilation pipe connections, this kind of parts can be called "flange parts". But this connection is only a part of a device, such as a connection between a flange and a pump, and it is not good to call the pump "flanged parts". Smaller valves such as valves can be called "flanged parts".
Flange connection or flange connection, it is to point to by the flanges, gaskets and bolts are mutually connected as a set of sealing structure detachable connection, pipe flange refers to the plumbing for piping flange, used in equipment refers to the import and export of the flange of the equipment. There are holes in the flanges, and bolts make two flanges. The flange is sealed with gasket. Flange threaded connection (thread connection) flange, welding flange and clamp flange. The flanges are used in pairs, and the low pressure pipe can be used with wire flanges, and the welding flange is used for more than four kilograms of pressure. Between two flanges, add a gasket and tighten the bolt.
The A20 gasket, the size of the gasket size reference flange cover dimension can be viewed HG/T20592 ~ 20635-2009 page 128 has detailed dimensions. Flange: the Flange is also called a Flange. The flange is the part that connects the pipe with the pipe and the valve. There are holes in the flanges, and bolts make two flanges. The flange is sealed with gasket. Flange threaded connection (wire) flange and welding flange and card flange.
