What do you mean by flange Pg16 Dg100?
That's the meaning of DN100 PN1.6 MpaDg Pg is the old engineer used to say soIt is recommended to see the JB/T 81-94 flange standard
Indicates that the pressure level of the flange is 16 kg, or 1.6MPa, and the flange diameter is 100mm.
Flange performs China chemical industry standard HG5022-58;Pg16: nominal pressure 1.6MPa;Dg100: nominal diameter 100mm.Flanges (Flange), also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.
That should be PN16DN100. The pressure is 16 kg. Nominal diameter DN100 pipe outer diameter 108 flange inner diameter 110
