Q:How should we get to know the flange?

What's the flange? Most books say this: flanges and their gaskets and fasteners are commonly referred to as flanged joints. Flange joints are widely used in engineering design and involve a wide range of parts and components. It is a pipe design, pipe fittings, valves indispensable part, but also other industries, such as heat, water supply and drainage, heating, ventilation, automatic control and other projects in a commonly used components.That may be very standard, but understand the people may be less.

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:What is the welding flange valve, is it the flange and pipe welding, and then the valve flange with bolts on the pipe connected to the flange? What is the threaded flange valve?

The valve is the valve flange welding flange welding flange installed in the pipeline, the valve is threaded flange threaded flange installed in the pipe threading to install the valve, but no difference for the valves, pipeline installation flange just not in the same way.

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: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:In building engineering, what is called "flange" means detailed point?

According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad.Flange connection, easy to use, able to withstand greater pressure.Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.

Q:What is the output flange? What's the function?

Flange connection, easy to use, able to withstand greater pressure.Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.

Q:Inside and outside the plastic coated steel plastic composite pipe to flange connection

1, press groove with groove machine2, clamps one, the short pipe flange one, carries on the connection3, after the connection, corresponding to the valve flange is OK, remember to see the number of flange holes in advance.

Q:Flange specification PL20 (B)

Hello, I am Hebei wealthrun Pipe Industry Co. Ltd, we are the production of flange manufacturers, this is a Ministry of chemical industry standard, PL is the flange nominal diameter is 20. B most finger outside diameter.

Q:there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?

The 23 attack drill 24 means with drill out the light hole cylindrical surface depth of 24mm, and then use the screw thread tapping into the effective depth of 23mm, which uses standard gauge M12 can be screwed into the 23mm, however, it should be marked drawings of consultations, the final hole should have 1.5 to 2 times the pitch pitch (M12 is 1.75), is about 3mm of the margin, or even the best teacher is also very difficult to achieve. This is my old fashioned experience for reference.
