Q:What are the common materials and grades of aluminum alloy flanges?
The aluminum alloy flange is a connecting part between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used in the flange of the equipment entrance and exit. It is used for the connection between the two equipments, 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.
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:What is blind through flange?
The through flange is used to connect the two pipe fittings, and the two flanges are connected together by bolts. For the blind flange end of the pipeline, to shut off the pipeline
Q:To set the price
I checked it on the InternetThere are several kinds of this one you sayThe cheapest is more than 100, and the most expensive is five hundred
Q:What's the flange surface?
Flange 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 usePL welding plate flange with flange, SO diameter, WN butt welding neck flange; IF integral flange, SW socket welding flange, TH threaded flange; loose flange ring PJ/SE welding, PJ/RJ welding ring flanges; flanges BL, BL (S) lining flange
Q:What's the difference between a clip flange and a flange?
Flanged butterfly valves are flanged on the valve and bolted to both ends of the valve to connect the flanges to the pipe flanges. Sealing surface wear resistance, long service life. The utility model has the advantages of unique structure, flexible operation, labor saving, convenience, and high and low pressure without the pressure of the medium
Q:What are the application technologies of welding flanges?
First, the level of welding flanges and their technical requirements shall comply with the corresponding requirements of JB4726-4728. 1, nominal pressure PN for 0.25MP-1.0MPa carbon steel, austenitic stainless steel forgings, allowing the use of grade I forgings. 2, in addition to the following provisions, the nominal pressure of PN 1.6MPa-6.3MPa forgings shall meet the requirements of secondary or secondary forgings. 3, in line with one of the following conditions, and shall comply with the requirements of forging III: (1) PN = 10.0MPa nominal pressure flange forgings; (2) the nominal pressure PN>4.0MPa chrome molybdenum steel forgings; (3) PN>1.6MPa nominal pressure and the working temperature is less than or equal to -20 degrees Celsius ferritic steel forgings.
Q:RJ what flange is the sealing surface?
RJ is a form of flange sealing surface
Q:SB 1379-NP15 which flange standard is the flange diameter, pitch, thickness, screw hole number and diameter?
2, international pipe flange standards of several systems1) European flange system: German DIN (including the Soviet Union), British standard BS, standard NF, Italian standard UNIA, nominal pressure: 0.1, 0.25, 0.6, 1, 1.6, 2.5, 4, 6.4, 10,, 16, 25,, 32, 40B, probable path: 15~4000mm (maximum diameter change and selected flange specifications and different flange pressure rating surface)C structure: flat plate, flange, welding ring sleeve type, crimping sleeve type, welding crimping sleeve type, welding ring sleeve type, welded, threaded neck, and integral flange coverD, flange sealing surface: flat surface, concave surface, concave convex surface, mortise and tenon surface, rubber ring joint surface, lens surface and diaphragm welding surfaceE, the Soviet Union in the 1980 release of OCT with standard pipe flanges recorded similar to the German DIN standard, no traces2) American flange system: American ANSI B16.5, steel pipe flanges and flange fittings, ANSI B16.47A/B, big diameter steel flanges, B16.36 orifice flanges, B16.48 characters, flanges, etc..
Q:What's the flange size?
Is the square distance is under the eyes of the flange size
