What is a "flanged valve with short pipes A and B"?

Flanged valves with short pipes A and B are generally used for pipe engineering with socket connection. "Short pipe A" is a pipe section with socket and flange, which is used at the inlet pipe side of the valve; "Short pipe B" is a straight pipe section+flange, which is used at the outlet side of the valve.

Extended data:

Flange connection refers to fixing two pipes, fittings or equipment on one flange respectively, adding a flange gasket between the two flanges, and completing the connection with bolts. Some pipe fittings and equipment have their own flanges, which are also flange connections.

Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. In the industrial pipeline, in the home, the pipeline diameter is small, and it is low pressure, so the flange connection is invisible. If you are in the boiler room or production site, there are flanged pipes and equipment everywhere. ?

According to the connection mode, the flange connection types can be divided into: plate flat welding flange, flat welding flange with neck, flat welding flange with neck, socket welding flange, threaded flange, flange cover, loose sleeve flange with neck welding ring, flat welding ring loose sleeve flange, annular grooved flange and flange cover, large diameter flat welding flange, large diameter high neck flange, splayed blind flange, loose sleeve flange of welding ring, etc.
