Blind Flanges vs Blank Flanges – What’s the Difference
blank flanges and Blind flanges are commonly used in industrial metalworking but have distinct differences. Blind flanges seal off pipes or vessels, while blank flanges have solid surfaces without holes. Understanding these differences is crucial for making informed decisions in projects. In this blog post, we will discuss why it’s important to understand the difference between these two types of flanges so that you can make the best decision for your project.
What is a Blind Flange?
A blind flange is a type of pipe flange that has no opening, or “bore,” in its centre. Instead, it has a solid face that is bolted onto another part of a pipe or other piece of equipment. These types of flanges are most commonly used when there is an unused connection point on a pipeline or piece of equipment that needs to be sealed off temporarily or permanently. They are also used to terminate pipes and other equipment when it needs to be disconnected from the system.
What is a Blank Flange?
A blank flange is a flat, usually circular plate with no openings. It’s used to cover or close the end of a pipe, valve, or vessel. Blank flanges are commonly used in piping systems for maintenance, testing, or when a future connection might be required. They’re available in various materials and sizes to suit different applications.
Difference Between Blind Flanges and Blank Flanges
- A blind flange is a type of flange that is used to seal off the end of a piping system.
- A blank flange is a type of flange that is flat, usually circular, and does not have any openings. It is used to cover or close the end of a piping system temporarily or when a future connection might be required.
- Blind flanges are used when a pipe needs to be sealed off permanently, and no fluid or gas needs to pass through the pipe.
- Blank flanges are used when a pipe needs to be sealed off, but there is still fluid or gas passing through the pipe.
- Blind flanges are typically made from forged steel, cast iron, stainless steel, brass, or plastic.
- Blank flanges can be made from any material that is compatible with the rest of the piping system.
Conclusion:
In conclusion, understanding the differences between blind and blank flanges can help ensure that you make the right choice for your project. Blind flanges should be used when capping off an unused connection point on a pipeline or piece of equipment, while blank flanges should only be used temporarily when access is needed inside a pipe or line without having to disconnect it from its other components. By understanding these differences between blind and blank flanges, you can save yourself time and money by making sure you select the right type for your application!
