Stainless steel socket welding Flange

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's the flange size?: Flanges, also known as flanges, are flanges that connect the pipe to the pipe and connect to the end of the pipe. The flange is lined with bolts to secure the two flanges.

Q: What's the flange? What is its structure and function?: I just learned this introduction on Monday. Flanges are a kind of discoid parts. They are the most common in pipe engineering. Flanges are used in pairs. In pipe engineering, flanges are used mainly for pipe connections. In the need to connect the pipe, all kinds of installation of a flange, low pressure pipe can use wire connection flange, more than 4 kilograms pressure use welding flange. Seal points between the two flanges, then fasten with bolts. Different pressure flanges have different thicknesses and use different bolts. 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. In the two plane in the vicinity of the use of bolted connections, and closed parts are generally referred to as "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts."". 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: Two standard reference flange standard what is the standard? What is the difference between the national standard and the national standard?: Two standard flange without standards, such as wall thickness to slightly worse, there are some errors in size, in general, can still use, but compared with GB flange, it must be unqualified

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 does the Rc-RF in the flange stand for? What do they stand for?: Rc is the threaded flange,The internal teeth are 55 degrees of degree of PT teeth, the standard of the teeth, the Japanese standard is JIS B0203, the European standard is ISO, the 7-1 German standard is DIN 2999,RF, as mentioned upstairs, means that the sealing surface is bulging

Q: What does "-150# SO/FF" mean by flange 4?: American Standard, pressure rating of 150, hubbed flangeSealing surface plane of flange

Q: What's the meaning of the middle flange? What's the difference between the flange and the flange?: for example, the flange valve flange has three, in the channel on the side flange, in the middle to connect the valve cover for the flange in the middle flange.

Q: The equipment itself, metal, is the conductor. Why do we have to do the cross connection at the connecting flange? A little more detailedFlange is bolted through, you say that the anti - corrosion treatment, that is, paint what, but why did the anti-corrosion treatment, but it is easy to spark it? The pipeline carries natural gas. For example, say thank you: Inflammable and explosive places is to prevent power leakage and electrostatic spark using conductive metal will better connect the two flange reliable, pipeline grounding, flange generally corrosion caused by poor contact is easy to produce sparks, in order to prevent the accident of flange jumper.

Q: Now in chemical, flange pn2.: Must be noted that the new and old standard flange PN units are not the same! The old standard unit is the kg/cm facility. The unit is MPa. that is the old standard PN2.5 corresponding to the new standard PN0.25.
