Without material, it can't be reported.

1. Due to historical reasons, some length units still use the unit of inches. The conversion between inches and metric (also known as meters) is: 1 inch = millimeter = 8 cents, and DN10 is equivalent to 3 cents in the metric system.

Others, such as: DN25 is equivalent to 1 inch in the British system; DN20 is equivalent to 6 points on the British scale; DN15 is equivalent to 4 points on the British scale; --Wait a minute.

2. DN10 is the difference code of pipe diameter, which does not represent the outer diameter or the inner diameter, and cannot be used for calculation.

DN10 refers to the valve whose mouth is very ten millimeters and should be three points, as shown in the figure below, the diameter is eighty millimeters, and the pressure is sixteen kilograms.

This valve size chart is for you! DN10 = 3 8 inches.

DN refers to the diameter of the male car, DN100 is the inch flange: the outer diameter of the flange is 220mm, the bolt hole spacing is 180mm, the bolt diameter is 18mm, the number of bolts is 8, and the flange thickness is 22mm. It is specified as a flange size table (GB9119).

The corresponding 1-inch tube is DN25, and the diameter is 25 mm.

The diameter of the 5-inch pipe is DN125, and the diameter is 125 meters; The diameter of the 4-inch pipe is DN100, and the diameter is 100 mm; The diameter of the 3-inch pipe is DN80, and the diameter is 80 mm; The diameter of the 2-inch pipe is DN50, and the diameter is 50 mm.

The expression of the diameter of the pipe shall comply with the following provisions:

For water gas transmission steel pipes (galvanized or non-galvanized), cast iron pipes and other pipes, the pipe diameter should be expressed by the nominal diameter DN; Seamless steel pipes, welded steel pipes (straight seams or spiral seams), copper pipes, stainless steel pipes and other pipes, the pipe diameter should be expressed by the outer diameter wall thickness.

For reinforced concrete (or concrete) pipes, clay pipes, acid-resistant ceramic pipes and other pipes, the pipe diameter should be represented by the inner diameter d; For plastic pipes, the diameter of the pipe should be expressed according to the method of product standards; When the design uses the nominal diameter dn to represent the pipe diameter, there should be a comparison table between the nominal diameter dn and the corresponding product specifications. <>

Metric diameter: 15-2000mm; Nominal pressure:; GB T9112-2000 (GB9113·1-2000 GB9123·4-2000).

DN100 is an inch flange: the flange outer diameter is 220mm, the bolt hole spacing is 180mm, the bolt diameter is 18mm, the number of bolts is 8, and the flange thickness is 22mm.

Flange Pad Standard:

Depending on the pressure level, there are also different materials for flange pads, ranging from low-pressure asbestos pads, high-pressure asbestos pads to metal pads.

1.By material, it is divided into carbon steel, cast steel, Kai blind alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leach, PPR, etc.

2.According to the production method, it can be divided into forged flange, cast flange, splicing flange, cut flange, and rolled flange (super large model).

3.According to the manufacturing standard, it can be divided into national standards (Ministry of Chemical Industry Standards, Petroleum Standards, Electric Power Standards, Machinery Identification Department Standards, Marine Standards), American Standards, Japanese Standards, Russian Standards, etc.

Summary. Hello, glad to answer for you. DN80 flange 10 pressure size detail This is a plane flange with a nominal diameter of 80, with 89 pipes, therefore, the flange inner hole 89, the thickness of about 25, the diameter of the drilling hole 18 4, on the M16 bolt.

Hello, I'm glad that Hu Nianmao answered for you. DN80 flange 10 pressure size details This is a nominal diameter of 80 plane flange pants buried, with 89 pipes, so Gaoxin, flange inner hole 89, thickness about 25, drilling diameter 18 4, on M16 bolts.

Hello dear, flange valve DN400** is about 200 yuan a. The flange valve has the characteristics of light mass mold rolling, and the inside of the valve body of the flange valve is made of high-grade lightweight alloy materials, which is strong and clever, but the weight is light, which makes the installation and use very convenient. In addition, the valve base of the flange valve is in a parallel shape, which can make the valve always keep a certain distance from the ground or wall, which can prevent water stains and dirt from damaging the valve body of the valve, and is conducive to prolonging the life of the valve.

The valve body of the flange valve usually adopts the treatment method of integral rubberization, which makes the whole valve a whole and the tightness of the instrument is more excellent.

DN1000 represents the nominal diameter of the electric butterfly valve and the nominal pressure of the electric butterfly valve. The opening and closing of the butterfly valve is controlled by a power signal. It can be used as a shut-off valve, control valve and check valve for piping systems.

With manual control device, once the power failure occurs, it can be temporarily operated manually, so as not to affect the use.

Hello, manual butterfly valve is a commonly used fluid control device, which is suitable for flow control of various media. Ordinary flange is a common connection method, usually used for low-pressure, low-temperature, general medium pipe connection. For manual butterfly valves below DN100, if the medium temperature, pressure, flow rate and other comic parameters are within the range of the bridge-fitting finger of the ordinary flange, then it is okay to use the ordinary flange to be sensitive to the hole, but the following points need to be noted:

1.Confirm that the standard and size of the flange match to ensure the robustness and tightness of the connection. 2.

Confirm that the flange and butterfly valve are made of compatible materials to avoid leakage or damage caused by materials that are not resistant to corrosion or adapt to the medium. 3.Confirm whether the rated pressure of the flange and butterfly valve are consistent to ensure safe and reliable use.

In summary, there are many factors that need to be considered when using ordinary flanges to connect manual butterfly valves, and if you are unsure whether it is suitable or not, it is recommended to consult a professional technician or use a special connection method.
