Any spot facing or back facing shall not reduce the flange thickness to less than the flange thicknessspecified. When spot facing is used, the diameter shall be large enough to accommodate the outside diameter of the equivalent normal series of washers in accordance with EN ISO 887 for the bolt size being fitted. The bearing surfaces for the bolting shall be parallel to the flange face within the limits given in Table 22. When a flange is back faced a minimum fillet radius, R2 (see Figure 17) in accordance with Table 23 shall be maintained.1.

flange connections, which are used for two kinds of pipes, fittings, or devices, are first fixed in a flange flange, and between the two flanges, flange pads are bolted together, which completes the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, not visible flange connection.

Flanges Introduction:A flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or crewed into such systems and then joined with bolts.Product Specification:1. Standard:JIS B2220 2. Type:SOP; SOH3. Pressure Class:5k;10k;16k;40k4. Dimension:DN10-20005.

Forged Carbon Steel Stainless Steel Pipe Flanges

Face finish: The finish on the face of flange is measured as an Arithmetical Average Roughness Height(AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH-500AARH(3.2Ra to 12.5Ra). Other finishes are available on requst, for example 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra or 6.3/12.5Ra. The range 3.2/6.3Ra is most common.1. Standard:JIS B2220 2. Type:SOP; SOH3. Pressure Class:5k;10k;16k;40k4. Dimension:DN10-20005.

     Carbon steel flange, that is, a flange plate or end flange connection made of carbon steel. It contains a flange made of carbon steel, called a carbon steel flange. Common materials are cast carbon steel grade WCB, forgings A105, or Q235B, A3, 10#, #20steel, 16 manganese, 45 steel, Q345B, etc.Usually to prevent rust flange surface has an electroplating layer (yellow zinc, white zinc, etc.), or brush antirust oil and spray antirust paint.Chinese national standard for carbon steel flange GB/T9119-2010 marine standard CB M1001-81 thermal power standard D-GD87-1101 1.

Flange plate designs are uniform in any given size regardless of materials used to create them. This allows a 6-inch (15 cm) black pipe flange to mate perfectly with a 6-inch stainless steel flange. The flange plates will have a serrated finish on the inside mating surface, which allows the plate to seat into the gasket material. This ensures a perfect seal between two joining pipes.1.
