CBM Blind Flanges

The formal title of blind disk is Flange cover, and some are in addition referred to as blind flange or pipe plug. It is a flange barring a gap in the core and is used to seal the pipe opening. The attribute is the equal as that of the head and cap, barring that the blind seal is a removable sealing device, and the seal of the head is now now now now no longer geared up to be opened again. There are many types of sealing surfaces, which consists of plane, convex, concave and convex surface, tenon and groove ground and ring connection surface. The elements are carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR.



From the exhibit off up of the blind plate, it is generally divided into plate range flat blind plate, mom or father eight blind plate, plug board, and gasket ring (plug board and gasket ring are blind to every and each and every other). The blind plate performs the attribute of isolation and cutting, and the attribute of the head, pipe cap and welding plug is the same. Due to its wonderful sealing performance, it is commonly used as a dependable potential of isolation for constructions that require complete isolation. A flat plate blind is a sturdy circle with a cope with that is used in constructions that are commonly isolated. The figure-8 blind plate is one-of-a-kind like a figure-8, one supply up is a blind plate, and the outstanding furnish up is a throttle ring, on the precise hand the diameter is the equal as the diameter of the pipe, and it does no longer play a throttling role. The figure-8 blind plate is reachable to use, when it needs to be isolated, the blind plate cease is used, and when every and each and every day operation is required, the throttle ring give up is used, and it can in addition be used to fill the set up hole of the blind plate on the pipeline. Another attribute is that it is in truth marked and reachable to hit upon out out the set up status.

Production process

Generally, there are 4 types: forging, casting and forging, medium plate cutting, and casting. Among them, the cost of forging merchandise is the highest, accompanied with the recommended beneficial useful resource of the use of way of medium plates, and casting and forging is the lowest. Casting is the most most applicable process. The pinnacle notch is suited for forging and core plates, and the casting and forging are barely worse.

Where the blind plate is applied

1. In the special start-up practise stage, when the electrical energy take a exhibit off up at or tightness take a show off off up at of the pipeline can no longer be carried out at the equal time as the related equipment (such as turbines, compressors, gasifiers, reactors, etc.), a blind plate have to be set at the connection between the equipment and the pipeline.

2. When the machine is stopped, if the pipeline is then as swiftly as more in operation, a blind plate is set at the shut-off valve.

3. When the laptop computer laptop computer laptop computer pc is multi-series, the predominant pipeline from out of doorways the boundary local is divided into loads of pipes to enter every and each and every series, and a plate is set at the shut-off valve of every sub-pipeline.

4. When the devices desire to be commonly maintained, inspected or switched with every and each and every other, and the equipment concerned desires to be barring a doubt isolated, a blind plate is set at the shut-off valve.

5. When the strategy pipeline of the pressurized pipeline and the displacement gas pipeline (such as nitrogen pipeline and compressed air pipeline) is related to the equipment, a plate is set at the shut-off valve.

6. If the technique medium needs to be headquartered in a unified series system, a blind plate have to be set up in the reduce as quickly as greater of the shut-off valve.

7. The exhaust pipe, liquid discharge pipe and sampling pipe of equipment and pipeline choose to be furnished with blind plate or plug in the as quickly as higher of the valve. Except for property that are non-toxic, non-hazardous to fitness and non-explosive hazards.

8. When the laptop is built in stages, the interconnected pipelines are set up at the shut-off valve to facilitate the subsequent inserting up of the project.

9. When the computing device is in each day production, some auxiliary pipelines that father or mother out upon to be barring a doubt preserve away from off ought to in many situations be set up with blind plates.
