SS400 carbon steel blind flange is a type of carbon steel blind flange with many advantages and applications. Elite Piping Manufacture is committed to producing high-quality SS400 carbon steel blind flanges, and this article will help us learn about them.

The flange blind plate is also called the blind flange; its real name is the blind plate. It is a type of flange connection. One of its functions is to block the end of the pipeline, and the second is to facilitate the removal of debris in the pipeline during maintenance. In terms of blocking, it has the same function as the head and the pipe cap. However, the head cannot be disassembled, while the flange blind plate is fixed with bolts and is very convenient to disassemble.

The materials of the flange blind plate are carbon steel, alloy steel, stainless steel, plastic, etc. The flange blind plate is used to block the end of the pipeline. There are welded flange blind plates and flange covers (flange covers are bolted). The flange cover is the flange blind plate, and the flange blind plate is not only in the form of flange covers but also welded flange blind plates, butt-wound flange blind plates, etc.

Flanges can be categorized into different types based on the materials used, such as carbon steel, stainless steel, and alloy steel. Carbon steel flanges contain carbon steel materials divided into A105 materials, Q235 materials, 16MN materials, 20# materials, etc. Since SS400 carbon steel flanges have no anti-corrosion function, the main anti-corrosion treatments include oiling, painting, and galvanizing. According to the production process, it can be divided into forged flange, cast flange, medium plate rolling, and medium plate cutting. Among them, the high-quality one is forged flange, followed by rolling and then casting.

The Advantages Of SS400 Carbon Steel Blind Flange

The SS400 carbon steel blind flange offers excellent heat resistance, with a softening temperature of 140 degrees when operating in water at 70 degrees.

Outstanding impact resistance: This flange demonstrates remarkable impact strength, surpassing that of other solid wall pipes and achieving a ring stiffness equivalent to 1.3 times that of solid walls.

Long service life: the service life of the pipe is more than 50 years under the rated operating temperature and pressure, and it is UV-proof and radiation-proof so the product will never fade.

Good corrosion resistance: except for a few hydrogenating agents, it can resist corrosion from various chemical media. The flange is exceptionally resistant to acids, alkalis, and corrosion, ensuring it will not rust, corrode, breed bacteria, or suffer from electrochemical corrosion.

Effective thermal insulation: With a thermal conductivity of 0.21-0.24W/mK at 20 degrees Celsius, PP-R pipes offer significantly better thermal insulation than steel pipes (43-52W/mK) and copper pipes (333W/mK).

The Applications Of SS400 Carbon Steel Blind Flanges

SS400 carbon steel blind flange are made of carbon steel, such as SS400, and have several applications. They are primarily used to fully isolate production media to prevent the loose closure of shut-off valves, which could disrupt production or lead to accidents. These blind flanges should be installed at equipment connections, before and after shut-off valves, or between two flanges and other locations that require isolation.

The Production Process Of SS400 Carbon Steel Blind Flange

The forging process of SS400 carbon steel blind flanges involves various methods such as pendulum rolling, pendulum rotary forging, roll forging, wedge cross rolling, ring rolling, and oblique rolling.

Precision forging is essential for achieving complex shapes and high precision with lower forging force. During cold forging, the production blank of carbon steel blind flanges undergoes deformation and work hardening, necessitating the use of high-strength forging dies and hard lubricating films to prevent wear and adhesion.

Additionally, an intermediate annealing process is necessary to enhance the deformation resistance of carbon steel blind flanges and prevent cracks.

Lastly, a carbon steel blind flange is a versatile component that can be secured to the end of a pipe using various methods, allowing for easy movement on the pipe end.

SS400 carbon steel blind flange greatly impacts the machinery industry and has greatly contributed to economic development. Therefore, we must pay attention to the development of carbon steel blind flanges, follow the development trend of modern industry, and keep pace with the international carbon steel flange forging industry. Elite Piping Manufacture specializes in producing high-quality carbon steel flange products with reliable quality and excellent performance, which has played a huge role in industrial construction development.The above is an introduction to SS400 carbon steel blind flanges.
