Q: There are many kinds of flanges. Many different looks. How can they be called flanges?: The flange connection (flange, joint) consists of a pair of flanges, a gasket, and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, the tight connection. A flange connection is a detachable connection. The connecting parts can be divided into containers, flanges and tubes; in accordance with the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange 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 welding flange, large rigidity, suitable for high temperature pressure. 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, suitable for flammable and explosive, toxic medium and high pressure situations.

Q: Flange German standard DIN, pleaseND16 what does that ND mean?It's ND in German standard DIN, not nominal diameter DN: Should mark "DN", is the nominal diameter of the code.Is the nominal diameter size after the roundness of the numerical repair to the mantissa, in order to simplify the mark.Germany, China ISO, nominal diameter are DN.

Q: How much screw does the flange of DN80 fit?: Look at your current range of use, basic stud 16*100

Q: What do you mean by flange specification 10K?: This is a JIS standard, that is, a Japanese standard. Domestically, it is a ship's standard pressure indication. "10K" means "PN1.0MPA".

Q: Are flanges and bushings the same thing?: Flanges and bushings are not the same thing.Turn left and turn right |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. 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". 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".The sleeve is a cylindrical mechanical part that is attached to the shaft. It is a part of the sliding bearing.Generally speaking, the axle sleeve and the bearing seat adopt the interference fit, and the shaft and the gap fit.

Q: Who knows the connection flange - 2.5 inches RFSO DIN PN 40? What does that mean? What's the country's standard, RFSO?: RF SO means a sudden neck flange, DIN is the German standard, PN40 is the pressure level (40 kg) pressure.Elbows DN65 (73) - 73 OD x 2.6 WT, which means nominal diameter DN65 elbow, the outer diameter of the actual size of 73mm, 2.6WT means 2.6mm thick.Ball VALVE - 3 PIECE - 3 PIECE DN2.5''- SW is 3 mm thick tube, DN2.5 "means a false statement, but said 2.5", it can be said DN65, nominal diameter refers to the ball valve, SW socket welding.

Q: What is the American Standard flange 150LB: 150LB means that the pressure (pounds) is converted to PN, which is PN2.0MPA, that is, 20 kg pressure

Q: What does this mean in the flange, Pg10Dg50?: 10 pressure, 50 way diameter, is only a specification, specific you are what standards need to know.

Q: How are bearings fixed on the plate with flanges?: There is a screw hole on the flange

Q: What do steel flanges mean?: Also called flanges or flanges. Forged steel flange is based on the invention of cast steel flange into production, its strength is much higher tube and pipe connected than cast steel flange parts, connected to the pipe end. Forged steel flanges are provided with bolts to secure the two flanges. Gasket sealing between forged steel flanges. Forged steel flanges (flanged pipe fittings) with a forged steel flange (flange flange or pipe). The utility model can be formed by casting, and can also be formed by thread connection or welding. The flange joint (flange, joint) consists of a pair of flanges, a gasket, and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. A flange connection is a detachable connection. The connecting parts can be divided into vessel flange and pipe flange. According to the structural type, there are integral flanges, looper flanges and threaded flanges.
