Advantages of blind flange connection

A blind flange looks like a plate with bolts holes around. There is no inner hole on the blind flange comparing to other type flanges, so the blind flange is used to close the end of a vessel or piping system. Blind flange also be used for pressure testing for prevent the liquid or air flow.What’s the advantages of blind flange connection?

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

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

3.Furthermore, if the blind flange is working in a dusty or polluted environment, the necessary dust-proof devices and sealing devices should be added;

4.Of course, the general method of reducing mechanical wear is to use lubricants. For flanges, fluid static lubrication and hydrodynamic pressure lubrication can be used to deal with;

5.Magnetic levitation supports with higher technical precision can also be used to solve this problem.

6.The system has good stability and easy maintenance. The grooved pipe fittings connection method has unique flexibility, which makes the pipeline anti-vibration, anti-shrinkage and expansion capabilities. Compared with welding and flange connection, the stability of the pipeline system is increased. It is more suitable for temperature changes, thereby protecting pipeline valves and reducing damage to structural parts caused by pipeline stress.

Due to the simple connection operation of the grooved pipe fittings, the required operation space becomes smaller, which brings many convenient conditions for future maintenance. When the pipeline needs to be repaired and replaced, a section of the pipeline can be replaced, rotated or modified at will by loosening the two clamps. There is no need to damage the surrounding walls, reducing maintenance time and maintenance costs.
