Slip Blind vs Blind Flange – What’s The Difference
If you are looking to purchase slip blinds or blind flanges, it is important to understand the difference between these two components. While they may seem similar at first glance, there are actually some key distinctions when it comes to how they are used and what they do. Let’s take a closer look at each component so you can make an informed decision when making your purchase.
What is Slip Blind?
A slip blind is a type of flange that is designed for use in pipelines or other pressurized systems. The slip blind fits between two pieces of pipe and can be used to close off the line or isolate it from another system. It is also commonly used as part of a blowdown system on boilers, steam drums, and other pressurized vessels. A slip blind typically consists of two parts, the body and the closure plate. The body has two drilled holes for bolting it into place in between two pipes, while the closure plate seals off both ends of the pipe when installed.
What is Blind Flange?
A blind flange is similar to a slip blind in that it is also used to isolate one section of a line from another or close off an existing connection. However, unlike a slip blind which has two parts (body + closure plate), a blind flange includes only one piece with no internal bore or opening. This makes them ideal for applications where pressure testing needs to be done since they completely seal off the line when installed correctly. Additionally, because there are no moving parts, these types of flanges are much easier to install than other alternatives, such as valves or expansion joints which require additional time and effort for installation and maintenance.
Difference Between Slip Blind and Blind Flange
- A slip blind is a type of flange that is used to seal off a pipeline or other opening.
- A slip blind is inserted into the opening and then welded in place.
- A blind flange is a type of flange that is used to seal off a pipeline or other opening.
- A blind flange is welded to the end of a pipe or other opening.
- A blind flange can be used with a slip blind to create a double block and bleed the system.
- A blind flange is typically used when it is not possible or practical to weld a slip blind in place.
Conclusion:
Slip blinds and blind flanges both serve important functions in pipelines and other pressurized systems but have distinct differences when it comes to their uses and features. Slip blinds include two separate pieces (body + closure plate), while blind flanges consist of just one piece with no internal bore or opening, which makes them ideal for pressure testing applications. No matter which type you choose, understanding the differences between these components will help you make an informed purchase decision that best meets your needs!
