About Blind Flanges
A blind flange, also known as a blind disk or flanged pipe plug, serves to seal the end of a pipe. Unlike other flanges, it lacks holes in the center, functioning similarly to a pipe cap or plug. Its detachable nature allows for easy replacement or maintenance, distinguishing it from other flange types.
The primary function of a blind flange is to completely isolate the production medium, preventing any flow through the pipe opening. This is crucial for preventing production disruptions, avoiding accidents, and ensuring safety. Blind flanges are typically used at equipment nozzles, between two flanges, or on either side of shut-off valves.
Depending on the specific application, different types of blind flanges may be used. For instance, a figure 8 blind flange (figure-8 blank) is recommended for locations requiring isolation between flanges or shut-off valves, while a common round blind flange is suitable for single-use parts such as purging or testing.
Blind flanges feature various sealing surfaces, including flat, grooved, concave, convex, and ring joint surfaces, each suited for different sealing requirements and applications.

- Flange face type: RF (Raised Face), RTJ (Ring Type Joint)
Manufacturing Types and Costs
Generally, there are four types of manufacturing processes: casting, forging, medium plate cutting, and casting and forging. Among these, forging typically commands the highest price, followed by medium plate cutting, with casting and forging being the most economical. However, casting is generally considered inferior compared to the other methods. In terms of quality, forging and medium plate cutting are regarded as the best, followed by casting and finally casting and forging, which may exhibit slightly lower quality.
Casting Blind Flange
The casting flange blank boasts precise shaping, low processing requirements, and cost-effectiveness. However, it is prone to casting defects such as air holes, cracks, and inclusions. Additionally, the internal casting part may have poor streamline characteristics, especially if it's a cutting component, where the streamline is further compromised.
Forging Blind Flange
Forged blind flanges generally feature lower carbon content compared to cast flanges, making them less susceptible to rust. Furthermore, forgings exhibit a denser structure, superior streamlined shape, and enhanced mechanical properties compared to cast flanges. However, improper forging methods can result in larger or uneven grain structure and may lead to hardening cracks. Despite these advantages, casting flanges typically incur lower costs compared to forging.
Precautions When Use
Ensure that the method requirements are met while minimizing the use of blind plates. Each blind plate set must be labeled as either "usually open" or "usually closed." The placement of the blind plate should be determined based on safety considerations, cutting effectiveness, and process requirements.
