3、Convex blind flange advantage

The advantages of Convex blind flange are as follows:

1. Excellent sealing performance

The Convex blind flange can achieve excellent sealing performance through its unique sealing surface design and material selection. Whether it is plane seal, concave-convex seal or other forms of seal, the Convex blind flange can ensure that the medium in the pipeline or equipment will not leak, thus ensuring the safety and stability of production. This sealing performance is of great significance for preventing medium pollution and protecting equipment and environment.

2. Simple structure and convenient installation

The structure of the Convex blind flange is relatively simple, and it usually consists of three parts: the main body, the seal and the connector. This structure makes the installation and disassembly of the Convex blind flange very convenient and can quickly adapt to different use scenarios and needs. During pipeline maintenance, replacement or system debugging, the Convex blind flange can quickly achieve isolation and cut-off functions, improving work efficiency.

3. Recycling, environmental protection and energy saving.

Some Convex blind flanges made of special materials have the characteristics of be of simple construction. This kind of Convex blind flange has low energy consumption and pollution in the process of production and use, which conforms to the concept of green development. With the continuous improvement of environmental awareness, recyclable Convex blind flanges will gradually become the mainstream products in the market.

4. Wide range of application

Convex blind flanges are widely used in the sealing of pipelines and equipment in industries such as food processing. In these industries, Convex blind flange can effectively prevent media leakage and pollution, and ensure the safety and stability of production. At the same time, because of its simple structure and convenient installation, Convex blind flange are often used in pipeline maintenance and replacement, which provides strong support for industrial production.

5. Economical and practical

Although the initial investment of the Convex blind flange may be relatively high, its excellent performance and long life make the overall cost-effectiveness very high. The Convex blind flange can reduce the loss caused by medium leakage and pollution, and reduce the maintenance cost and production cost.

4、Convex blind flange application

Convex blind flanges have the following purposes.

1. Improve security

By setting the Convex blind flange, the medium leakage caused by the lax closing of the cut-off valve can be avoided, thus reducing the accident risk and improving the safety of the pipeline system.

2. Protect equipment and pipelines

In some cases, the pipeline system may be impacted by high pressure, high temperature or corrosive media. The use of Convex blind flanges can protect equipment and pipelines from these harsh conditions and prolong their service life.

3. Auxiliary device of safety valve

In some safety valves or pressure relief devices, Convex blind flanges are used as auxiliary devices to ensure that the flow of media can be quickly cut off in an emergency.

4. Isolated piping system

Convex blind flanges are used to isolate a part of the piping system for maintenance, overhaul or replacement of equipment. By installing the Convex blind flange, the medium flow in the pipeline can be cut off and the safety of the working area can be ensured.

5. Overhaul and replace equipment

In the pipeline system, the equipment needs regular maintenance and replacement. The use of Convex blind flanges makes this process safer and more convenient. By installing the Convex blind flange, the equipment that needs to be repaired or replaced can be isolated without affecting the operation of the whole pipeline system.
