What does flange JIS 10K mean
The flange thickness of different pressure is different, and the bolts they use are different. Water pumps and valves, when connected to pipes, are locally made of these devices, also known as flanges, also known as flanges. Around where there are two surfaces using bolt connection closed connection parts at the same time, generally known as the "flange", such as ventilation pipe connections, this kind of parts can be called "flange parts". But this connection is only part of a device, such as a connection between a flanges and a pump, and it is not good to call the pump "flanged parts". Smaller valves such as valves can be called "flanged parts".
3, according to petrochemical industry standard points: thread flange (PT), welding flange (WN), flat welding flange... Flanges are a type of disk parts that are most common in pipeline engineering and are used in pairs. In the pipeline project, the flange is mainly used for the connection of the pipe. In the pipe that needs to be connected, all kinds of installation flange, low pressure pipe can use the silk flange, 4kg above pressure of welding flange. Seal points between two flanges, then bolted with bolts. 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".
Flange type 1, according to the national norm: integral flange, threaded flange, butt welding flange, with flat welding neck flange, socket welding neck flange, butt welding band neck loose flange, plate, flat welding flange, butt welding plate loose flange rings, flat welding ring plate loose flange, flange ring plate loose flange, flange cover. 2, according to the chemical industry norm: integral flange (IF), threaded flange (Th), plate (PL) flat welding flange, butt welding flange with diameter (WN), with flat welding neck flange, socket welding flange (SO) (SW), the butt welding ring loose flange (PJ/SE), flat welding ring loose flange (PJ/RJ), lining flange cover (BL (S)), flange cover (BL).
