Q:What do you mean by flange?
According to the connected components can be divided into container flange and pipe flange. According to structure type, integral flange, loose flange and threaded flange. Integral flange are common flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange flange, rigidity, suitable for high pressure and high temperature conditions. The flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, for Yu Yiran, explosive, toxic medium and high pressure the occasion. Gasket is a can produce made of plastic deformation, and has a certain strength of the material.
Q:Taiwan version Ma flange effect, okay?
As far as I know, the medicine can be obtained except the Hongkong Edward pharmacy, and no other pharmacies can get it
Q:What does DN32 flange mean?
According to American Standard B36.10M 1-1/4 "is 42.2mm diameter is connected to the pipe is 42.2mm, the hole to see the pressure level or wall thickness determine the size
Q:SolidWorks cannot make a miter flange?
No tangency, tangency, no tangency, sheet metal can not be done
Q:What's the difference between RF flange and RJ flange?
The difference between the RF flange and the RJ flange is that the seal is different.RF flange is a face seal surfaceRJ flange is ring connection sealing surface
Q:PROE flat sheet metal design whole wall and the flange wall what is the difference?
General flat wall more, but both are useful, if a sheet folded 8 bend, flange 8 bending murals in the shape of a stretched out, but with a flat wall is painted 8 times,
Q:What's the flange? What's it for?
Flange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. It is also used for the flange on the inlet and outlet of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection) flange and welding flange and flange clamp.
Q:Is the flange fitted with a flange?
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".
Q:What is the maximum pressure of the flanges RF and RTJ?
The use of with concave convex surface with tongue and groove face flange is basically the same. Ring groove sealing surface (RTJ) is mainly used in high temperature and high pressure or both high working conditions. In American Standard flange, commonly used in Class 600Lb (part) and 900Lb, 1500Lb, 2500Lb grade pressure. In the German standard and national standard, often used in PNl0.0, PN16.0, PN25.0, PN32.0, PN42.0MPa flanges.
Q:In the heat exchanger calculation, the actual bolt section area of the cylinder flange is smaller than the required cross-sectional area. What's the matter?
Generally choose JB/T4700-2000 "pressure vessel flange" in the flange, you do not need to calculate
