Carbon Steel Blind Flange
A carbon steel blind flange is a solid plate used to seal or close the end of a piping system, preventing the flow of fluids while allowing easy access for future pipe extensions or maintenance. Crafted from carbon steel, carbon steel blind flanges boast high strength, durability, and resilience against wear and tear, rendering them fitting for diverse industrial applications, encompassing oil and gas, petrochemical, and power generation sectors.

Carbon Steel Blind Flange Models
Blind Flange Carbon Steel Design And Function
Design
Blind flanges carbon steel are typically solid discs with no bore or opening in the center. They feature a flat face on one side and a raised face on the other. The flat face provides a smooth surface for sealing, while the raised face creates a ridge to accommodate the sealing gasket. Blind flanges also have bolt holes around the perimeter for attachment to the flange end of the pipe or vessel. These bolt holes are usually arranged in a circular pattern and correspond to the bolt holes on mating flanges.
Function
The primary function of CS blind flanges is to seal the end of a piping system or vessel. They are installed by bolting them onto the flange end of the pipe or vessel, effectively blocking the flow of fluids. Blind flanges are commonly used for isolation, testing, or the termination of piping systems. They provide a reliable and leak-proof seal, ensuring the integrity of the system.
CS Blind Flange Dimensions
Carbon steel blind flange dimensions encompass crucial measurements defining their compatibility and performance within piping systems. Typically adhering to industry standards such as ANSI/ASME B16.5 or ASME B16.47, these dimensions include nominal pipe size (NPS), ranging from 6 inches to 787 inches, and pressure ratings from Class 150 to Class 2500.
Essential measurements comprise the outer diameter, bolt circle diameter, bolt hole size and number, flange thickness, and facing type, ensuring proper alignment, sealing, and structural integrity. These dimensions not only facilitate seamless integration into diverse industrial applications but also uphold the safety and efficiency standards mandated by regulatory bodies and engineering practices.
Carbon Steel Blind Flange Manufacturing Process
Material Selection
The process begins with selecting the appropriate grade of carbon steel based on the desired mechanical properties, corrosion resistance, and application requirements.
Cutting
Raw carbon steel material is cut into suitable sizes and shapes using cutting tools such as saws or shears. The cutting process ensures that the material meets the required dimensions for the blind flange.
Forging Or Forming
Forged blind flanges carbon steel are typically manufactured through the forging process. In forging, the heated raw material is shaped into the desired form under high pressure using mechanical or hydraulic presses. This process provides superior strength and grain structure compared to casting.
Machining
After forging, the blind flanges undergo machining operations to achieve precise dimensions and smooth surfaces. This includes operations such as turning, milling, drilling, and threading to create the required features, bolt holes, and sealing surfaces.
Heat Treatment
CS blind flanges may undergo heat treatment processes such as normalization, annealing, or quenching and tempering to enhance their mechanical properties, such as hardness, toughness, and machinability. Heat treatment also relieves residual stresses introduced during forging and machining.
Surface Finishing
Surface finishing operations, such as grinding or polishing, are performed to improve the aesthetic appearance and surface quality of the blind flanges. This helps ensure proper sealing and enhances corrosion resistance.
Quality Control
During the manufacturing process, quality control measures are enforced to ensure dimensional accuracy, material integrity, and surface finish. Non-destructive testing methods, like ultrasonic testing or dye penetrant inspection, may be used to identify any defects or imperfections.
Final Inspection And Packaging
Once manufacturing is complete, carbon steel blind flanges undergo a final inspection to verify compliance with specifications and standards. They are then properly packaged to protect them during storage, transportation, and handling before reaching the end user.
Precautions For Using Blind Flange Carbon Steel
- Since CS blind flanges are made of different materials and thicknesses, it is necessary to select the appropriate blind plate according to actual conditions during use;
- Before using carbon steel blind flanges, they must be cleaned and derusted;
- When installing blind flanges carbon steel, check the matching degree between flange connection holes and blind plate sizes;
- The fastening bolts of the blind flanges should be tightened as required and a sealing test should be carried out;
- It is recommended to conduct regular inspections on CS blind flanges that have not been used for a long time to prevent damage due to rust and other reasons.
