Q:The valve has a connection between the clamp and the flange. What's the difference between this and the connection?
The clamp is used for small caliber, and the flange is basically big bore and big pressure.
Q:What does flange WN80 (B) -40M mean?
WN butt welding flange 80 nominal diameter B series diameter 89, in fact, AB are 8940 diameter, 40 kg pressureM indicates that the sealing surface is convex
Q:The function of steam turbine cylinder flange and bolt heating device
The partition plate is used to fix the stationary blade and prevent the steam leakage between the stages. It divides the inner part of the turbine into several pressure segments so that the steam can change the potential energy into kinetic energy through the stator cascade, and then flow the steam into the moving vanes in the prescribed direction.The cylinder of the high temperature steam turbine should bear high pressure and temperature, and the tightness of the joint surface of the cylinder must be ensured. Therefore, the flange of the cylinder must be made wide and thick. In this way, the starting of the turbine will bring about a certain difficulty, that is, a larger temperature difference along the width of the flange. If the temperature difference is too large, the thermal stress will cause the cylinder to deform or produce cracks. Generally speaking, the cylinder is easier to heat than the flange, and the heat of the bolt is transmitted to it through the flange, so the bolt is heated more slowly. For the double cylinder unit, outer cylinder heating cylinder is much slower than the outer cylinder, the flange is more slowly, because the flange temperature rises slowly, hampered the cylinder thermal expansion between the rotor and the cylinder caused by excessive expansion, so that the turbine flow gap, friction.
Q:SolidWorks assembly problem (the second holes on the flange can not fit coaxially)
You see a screenshot of the I guess is the hole and flange you shell flange on the hole position is not the same (diameter distribution) please check the threaded hole hole diameter distribution Yuguang pay special attention to the thread size when the reference mark and position! ~
Q:Is the grooved pipe flange?
Grooved pipe fittings are a series of products. Flanges are only a kind of groove fittings.1, groove pipe fittings is a new type of steel pipe connecting pipe, also known as clamp connection, has many advantages.2, piping system shall be connected with groove type connection or flange connection, threaded pipe system; diameter equal to or greater than 100mm, should be used to segment the flange or groove type connector.3, groove fittings include two major categories of products:There are rigid joint, flexible joint, mechanical three way and groove type flange;The connecting pipe has the elbow, the three, the four, the reducer, the blind plate and so on.4 flanges are also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe and is 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.5, flange or flange joint, refers to the flange, gasket and bolt three mutual connection, as a group of composite sealing structure of removable connection. 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.6, in connection with the pipe, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts which are bolted and closed in the vicinity of the two planes are generally called flanges, and this kind of parts can be called flanges.
Q:How about the flange type 16 kilograms, 25 kilograms and 40 kilograms?
The kilogram above means that the flange is welded to the pipe and can bear the pressure, that is, the nominal pressure. First determine the pipe pressure, and then the pipe pressure to determine the flange bearing pressure. The difference is that the wall thickness is different. The material is low carbon steel.
Q:Steel flanges (mechanical machining) can produce forgings flanges? Grades range from B to pressure piping
To have a professional qualification certificate.
Q:Can the hole on the flange be threaded?
The flange bolt hole can tap out the internal thread.But I haven't seen it. There is no flange piece to do so, the direct bolt nut connection is convenient.
Q:Mechanical flange problems, there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?
The 6 holes of M12 are evenly distributed on one flange, the drilling depth of the screw hole is 24mm, and the depth of the wire tapping is 23mm.
Q:Diameter 198, pipe with big flange
If the number of large, suggest you give manufacturers drawings, if not the number, I suggest you buy the DN200 welding flange when the flange with.
