Q:Who can tell me what "DN" and "PN" mean in flanges, and what does PN16 stand for?
DN----- through the flange -- such as pressure DN15. with Phi 18 DN25.
Q:What is flange? Why is it called flange?
Flanges (Flange), also called flanges, flanges, or flanges. The flange is a connecting part between the shaft and the shaft, 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.
Q:Who knows, the difference between plate flange and hubbed flange in the application.
Hubbed flange is imported from abroad, used for gas valves, gas pipelines etc.. Because of a short neck, flange stiffness can be improved and bearing capacity improved.
Q:What is the waterline of flanges?
In addition, if the flange is connected with a non-metallic gasket, it is only possible to process the sealing water line; if the metal gasket is sealed, the water line is not processed.
Q:SolidWorks 2012 border flange profile editor cannot drag boundary line 20 ahSolid
2 methods, the first step to select 1 line, second generation flange flange contours drag select Edit flange vertical edge contour add size constraints. complete2 first generate the side flange directly, modify the sketch below the edge flange, and add dimensional constraints
Q:WF face flangeI'd like to ask what flange form WF is,
The pattern of the flange sealing surface: plane (FF), sudden surface (RF), (MF), convex concave groove (TG) and ring junction (RJ). So far, there is no other form of sealing surface, is the concave and convex surface (MF) write backwards,
Q:Can you have a more general idea?
Is the distance from the lens mount flange from to the photosensitive element between the interchangeable lens camera. In the design at the beginning of the fixed bayonet flange from each lens, for later design can be achieved after installation to bayonet infinity focus.
Q:Which flange is the front pipe case flange and the cylinder flange?
The front pipe case flange is the tube part, which is connected with the tube plate.
Q:Dn is 250, Pn25 flange, what is the hole distance?
Flange center hole distance d1=370mmFlange diameter D=425mmGB GB/T9113.1-2000
Q:How many kinds of flanges are there?
1. The flange is divided into flange, flange, threaded flange, socket welding flange and loose flange according to connection.2. according to the form of flange sealing surfaceFlange in accordance with its form of sealing surface can be divided into flat, convex surface, concave convex surface, tongue and groove surface and ring connection surface. There are 4 standards in our current flanges: National Standard (GB/T), machinery industry standard (JB/T), Sinopec General Corporation Standard (SH) and chemical industry standard (HG). The standard of the sealing surface of the name is different, see the table below the name of the sealing surface.Table cover name contrastSealing surface nameNational standard(GB) chemical industry standards(HG) Sinopec General Corporation standards;(SH) machinery industry standards;(JB)Plane plane (FF) full plane (FF) whole plane (FF) -Convex surface (RF), convex surface (RF), convex surface (RF), convex surfaceConcave convex surface, concave convex surface (MF), concave convex surface (MFM), concave convex surface (MF), concave convex surfaceTongue and groove face, groove face (TG), tenon (TG), tenon (TG), tongue and groove faceRing connection surface, ring connection surface (RJ), ring connection surface (RJ), ring connection surface (RJ), ring connection surface
