Description


Blind flange is also called blind flange. Its proper name is flange cover. It is a flange with no hole in the middle for sealing the pipe plug.

There are many types of sealing surface, including plane, convex, concave convex, mortise and groove surface, and ring connection surface.Blind flange production process is mainly divided into forging, casting, cutting, these three kinds.

Casting blind flange, the blank shape and size is accurate, the processing amount is small, the cost is low, but there are casting defects (porosity, crack, inclusion), the internal structure of the casting streamline is poor (if it is a cutting part, the streamline is worse).

Forging blind flange is generally lower carbon content than casting blind flange, and is not easy to rust. Forging streamline is good, the structure is relatively compact, and the mechanical properties are better than casting flange.

Specification


1. Improper forging process will also lead to large or uneven grains, hardening cracks, and forging cost is higher than casting flange.

2.  Forgings can bear higher shear force and tensile force than castings. The advantages of the casting are that it can make a more complex shape with a lower cost.

3. The advantages of the forging are that the internal structure is uniform and there are no harmful defects such as pores and inclusions in the casting.

4. The production process of cutting blind flange is to directly cut out the inner and outer diameter and thickness of the flange on the middle plate,and then process the bolt hole and water line.

5. The flange produced in this way is called cut flange. The maximum diameter of such flange is limited to the width of the middle plate.

Advantage


1. First of all, reasonable mechanical design structure can help us reduce the pressure and wear between flange surfaces.

2. In addition, the material and heat treatment process of Xinjiang blind flange also affect the overall quality of the flange.

3. In addition, if the blind flange works in dusty or polluted environment, necessary dust-proof device and sealing device shall be added.

4. Of course, the general method to reduce the mechanical wear is also necessary to use lubricant.

5. For the flange, the methods of hydrostatic lubrication and hydrodynamic lubrication can be used.

6. This problem can also be solved by using magnetic suspension support with higher technical accuracy.

7. The system has good stability and convenient maintenance.

8. The connection mode of grooved pipe fittings has unique flexible characteristics, which makes the pipeline have the ability of anti vibration, anti shrinkage and expansion.

9. Compared with welding and flange connection, the stability of the pipeline system is increased, which is more suitable for the change of temperature.

10. Thus protecting the pipeline valves and reducing the damage of the pipeline stress to the structural parts.

Application


1. Blind flange is mainly used to connect and fasten pipes, pipe fittings, etc., and maintain the sealing performance of pipe fittings. 

2. The blind flange can be disassembled to facilitate the disassembly and inspection of pipes.

3. Blind flange is anti-corrosion, acid and alkali resistant, and can be used in water conservancy, power, power station, pipe fittings, industry, pressure vessel, etc.

4. Stainless steel blind flange can be used in boiler, pressure vessel, petroleum, chemical industry, shipbuilding, pharmacy, metallurgy, machinery, food and other industries, which is convenient for the replacement of a certain section of pipeline.

5. The blind flange of reducer is mainly used for the connection between motor and reducer, as well as the connection between reducer and other equipment.

6. The butt welding flange cover is used to transfer the pressure of the pipeline, thus reducing the high stress concentration in France.
