Q:Flange valve Q41F-16C/P/R mark, specific meaning?
This is standard regulation, according to "JB/T 308 - 2004 valve type programming method" regulation:Q= ball valve4= connection type: flange1= structure: floating ball direct flow channelF= sealing surface material: fluoroplastic-16= nominal pressure: 1.6MPaC= body material: carbon steelP= body material: chrome nickel stainless steel, such as: 304R= body material: chromium, nickel, molybdenum stainless steel, such as: 316
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:PROE flat sheet metal design whole wall and the flange wall what is the difference?
but if not a lot of this piece of sheet metal bending, and the shape is not Affirmative square, with it is necessary to cut the flange murals one or several features.
Q:What's the meaning of the middle flange? What's the difference between the flange and the flange?
Fran: it's an exotic language. English Name: flange, flange is to make the two cavities connected to the protruding parts or components.
Q:What flange is the SOFF flange?
flanges BL, BL (S) lining flangeFlange sealing surface has a full plane FF, protruding surface RF, convex M, concave F, tenon surface T, groove surface G, ring connection surface RJ, general concave convex MF, mortise and tenon surface TG, ring connection surface RJ are paired use
Q:What is the reverse flange?
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". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
Q:What is the flange? What are its application areas and principles?
Flanges (Flange), also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, 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.Flanges are widely used in construction, power generation, machinery and many other fields, and their main functions are as follows:1. Connect the pipe and keep the sealing performance of the pipeline.2, to facilitate the replacement of a section of the pipeline.3, easy to disassemble check the pipeline.4, to facilitate the closure of a section of the pipeline.Classification of flanges1. carbon steel, cast steel, alloy steel, stainless steel, copper and aluminum alloy are classified by material2., the production method can be divided into forging flange, casting flange, welding flange and so on.3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB).
Q:Can the aluminum flange 6061 and the aluminum tube 6063 be welded directly? Will there be such a fracture?
1, welding can be no problem.2, as long as the welding process is fine.
Q:How to calculate the flange quote formula?
A formula for calculating flange quotations, but such formulas are widely spread over the network and vary from one to another, and the results are different. In fact, there is no constant formula for the price of the flange, but it depends on the specific process of production. So I decided to have a quotation about flange quotation and let you know how our manufacturers quote. In fact, there is nothing to keep secret.
Q:What is the waterline of flanges?
Its function is to form labyrinth seals when flanges are connected to reduce leakage of gas or liquid!Prepare a chart, but not.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.
