Introduction to Open hole blind flange and blind plate structure principle

Open hole blind flangeis a common sealing product for pipelines and equipment.。

1、Brief introduction of Open hole blind flange

Open hole blind flangeis a kind of flange with no hole in the middle, which is mainly used to plug the pipe mouth. Its function is similar to that of the head and pipe cap, but the blind plate seal is a detachable sealing device, and the head seal is usually not ready to be opened again.，The price is relatively low.。

2、Open hole blind flange use

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

1. Isolated piping system

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

2. Control medium flow direction

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

3. Overhaul and replace equipment

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

4. Auxiliary device of safety valve

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

5. Prevent medium leakage

The Open hole blind flange has excellent sealing performance, which can effectively prevent the leakage of medium in the pipeline. This is very important to protect the environment and personnel safety, especially when dealing with toxic, harmful or flammable and explosive media.

3、Introduction of Open hole blind flange characteristics

Open hole blind flangefeatures include Economical and practical, Environmental protection and energy saving, easy installation, Strong adaptability and Various materials，Excellent sealing performance can be achieved through its unique sealing surface design and material selection. Whether it is plane seal, concave-convex seal or other forms of seal, the Open 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.、It has the characteristics of recycling. This kind of Open 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 Open hole blind flanges will gradually become the mainstream products in the market.、Excellent performance and long life make the overall cost-effectiveness very high. The Open hole blind flange can reduce the loss caused by medium leakage and pollution, and reduce the maintenance cost and production cost.、The structure is relatively simple, usually consisting of three parts: main body, sealing element and connecting piece. This structure makes the installation and disassembly of the Open hole blind flange very convenient and can quickly adapt to different use scenarios and needs. During pipeline maintenance, replacement or system debugging, the Open hole blind flange can quickly achieve isolation and cut-off functions, improving work efficiency.、The materials are varied, including carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR. These Open hole blind flanges made of different materials can adapt to different working environments and media requirements, ensuring excellent sealing performance and service life under various working conditions. At the same time, some Open hole blind flanges made of special materials can also resist the corrosion and erosion of media and prolong the service life of equipment.，is carefully developed by Jianing combined with advanced technology。
