4、Double hole blind flange use

The purpose of Double hole blind flange is introduced as follows:

1. Auxiliary device of safety valve

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

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 Double hole blind flanges can protect equipment and pipelines from these harsh conditions and prolong their service life.

3. Convenient maintenance and repair

The disassembly of the Double hole blind flange makes the maintenance and repair of the pipeline system more convenient and faster, and improves the work efficiency.

4. Control medium flow direction

The Double hole blind flange can also be used to control the flow direction of the medium in the pipeline. By installing the Double hole blind flange, the flow path of the medium can be changed to meet the process requirements or optimize the production process.

5. Isolated piping system

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

6、Functional advantages of Double hole blind flange

The advantages of Double hole blind flange are as follows:

1. Excellent sealing performance

The Double hole 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 Double hole 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 Double hole 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 Double hole blind flange very convenient and can quickly adapt to different use scenarios and needs. During pipeline maintenance, replacement or system debugging, the Double hole blind flange can quickly achieve isolation and cut-off functions, improving work efficiency.

3. Recycling, environmental protection and energy saving.

Some Double hole blind flanges made of special materials have the characteristics of easy installation. This kind of Double hole 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 Double hole blind flanges will gradually become the mainstream products in the market.

4. Wide range of application

Double hole blind flanges are widely used in the sealing of pipelines and equipment in industries such as pharmacy. In these industries, Double hole 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, Double hole 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 Double hole blind flange may be relatively high, its excellent performance and long life make the overall cost-effectiveness very high. The Double hole blind flange can reduce the loss caused by medium leakage and pollution, and reduce the maintenance cost and production cost.
