Product Introduction

The stainless-steel figure-8 blind flange is blind flange made of stainless steel. It is similar to the carbon steel figure eight blind flange. It is also commonly used for pipe connection and sealing, but due to the characteristics of stainless steel, it is suitable for More special and demanding application scenarios.

The following are the relevant characteristics and information of the stainless steel eight-shaped blind flange:


1/2″-24″ DN15-DN1200

Pressure rating:

Similar to other flanges, stainless steel figure eight blind flanges are also suitable for different pressure ratings, such as Class 150, Class 300, Class 600, etc. The specific selection depends on the application scenario and needs.


Due to the corrosion resistance and high temperature resistance of stainless-steel materials, stainless steel blind flanges are used in more special environments, such as chemical industry, food processing, pharmaceuticals, marine engineering, etc. They are commonly used to shut off pipelines for maintenance, cleaning, overhaul, isolation of media or to prevent leaks.


1.Corrosion resistance: Stainless steel material has excellent corrosion resistance and is suitable for scenes dealing with corrosive media and chemicals.

2.High temperature resistance: Stainless steel is stable in high temperature environments, so it is suitable for applications that require high temperature resistance.

3.Oxidation Resistance: Stainless steel material is resistant to oxidation, which helps prevent rust and corrosion.

4.Various models: According to different needs, there are various stainless-steel types to choose from, such as 304, 316, etc., to meet different corrosion resistance properties.

Advantages and disadvantages:


  1. Good corrosion resistance, suitable for a variety of corrosive media.
  2. High temperature resistance can be used in high temperature environment.
  3. Oxidation resistance, long-term use is not easy to rust.
  4. Suitable for special industries, such as food, pharmaceuticals, etc.


  1. Stainless steel materials are relatively expensive, and the cost is high.
  2. Manufacturing and machining stainless steel flanges can be relatively complex.
  3. In some high temperature and high-pressure environments, special designs and materials may be required, adding cost and complexity.

Generally speaking, due to its material properties, the stainless steel eight-shaped blind flange is suitable for more special and harsh environments, but it is necessary to weigh its advantages and disadvantages when using it, and choose the appropriate type and specification according to actual needs.
