What is a Blind flange? blind plate specifications, models, and parameters

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 advantage is 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 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.、The materials are varied, including carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR. These 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 Blind flanges made of special materials can also resist the corrosion and erosion of media and prolong the service life of equipment.、It has the characteristics of recycling. This kind of 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 Blind flanges will gradually become the mainstream products in the market.、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 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.、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 Blind flange very convenient and can quickly adapt to different use scenarios and needs. During pipeline maintenance, replacement or system debugging, the Blind flange can quickly achieve isolation and cut-off functions, improving work efficiency.。

1、Brief introduction of Blind flange

Blind flangeis a common sealing product for pipelines and equipment.，it can be used in Natural gas industry, make paper, pharmacy, chemical lines, make paper and other industries，the product looks beautiful.。

3、Blind flange application

Blind flanges have the following purposes.

1. Overhaul and replace equipment

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

2. Prevent medium leakage

The 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. Auxiliary device of safety valve

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

4. Completely isolated medium

The Blind flange can ensure that the medium in the pipeline system is completely isolated, prevent the medium from leaking when maintaining, inspecting or switching equipment, and ensure the safety of personnel and the integrity of equipment.

5. Isolated piping system

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

5、How much is the Blind flange?

The Blind flange price is introduced as follows:

1. product model

Specifications and models have a great influence on the price of Blind flange, so different specifications and models have different selling prices. Customers can reasonably select product specifications and models according to their own needs, so that products can meet their own required standards in terms of specifications and prices.

2. raw material

The higher the cost of materials, the higher the price will be. In the process of purchasing products, users need to make a detailed understanding of the materials selected for products.

3. Company size

There are many manufacturers of products in Shanxi, and the strength, technology and after-sales of each manufacturer are different, so the quotation for Blind flange is naturally different.

4. Service factor

There is a close relationship between service and price. High-quality service can not only avoid all worries in the process of product use, but also improve the overall strength and comprehensive credibility of manufacturers. In order to improve the service quality, Jianing Blind flange manufacturers provide comprehensive services for customers and products before, during and after sale, and at the same time make the price as favorable as possible to new and old customers, so that the Blind flange price can meet the purchasing needs of customers.

5. cost of production

The production cost determines the price. The production cost here mainly includes technology, materials, technology, manpower and other related factors, among which the technology content is high, and the cost is relatively high, but the performance will be better; The better the quality of raw materials, the greater the cost and the longer the overall life of the product; If the manufacturer has a rational manufacturing process and strict production management system, and can make full use of human and material resources, then it can reduce the waste of expenses and production costs to a great extent, and the Blind flange just meets this condition, so as to ensure the high-tech content and high quality of products, it can also enjoy low prices.
