Testing for high efficiency filters

Components to be tested

1. Acceptance of raw materials.

2. Dimensions of each part formed.

3. Non-destructive testing.

4. Flatness inspection of the top and bottom of the tube plate.

5. Hole distance between each flange.

6. Outside diameter dimensions after machining.

7. The flatness between the flange sealing surface and the support surface of the pipe plate after processing.

8. The blue dot method of stainless steel surface inspection.

And for the normal operation of the equipment, we can add the following steps in the manufacturing process.

1. Control the deformation of the riveted joint forming.

2. Pay attention to the riveted leveling.

3. The thickness direction of the steel plate into the reservation.

4. The beveling of the upper and lower plates.

5. Anti-deformation control from the angle of welding.

6. Selection of anti-deformation tooling.

7. Deformation after the repair method.

The filtration equipment is a very important flange device, to ensure its sealing surface and connection size tolerance and position size tolerance, which is also a difficult point of equipment manufacturing, so in the process of manufacturing we should consider the following points.

1. The amount of processing left.

2. The processing of bolt holes and sealing surfaces.

3. The choice of bevel form.
