Vanstone Flange vs Lap Joint Flange – What’s the Difference

Vanstone Flanges vs Lap Joint Flanges

Vanstone flanges and lap joint flanges are two types of pipe flanges that serve different purposes in industrial applications. While they both function to join two pipes together, there are key differences between them. Understanding the difference between vanstone flanges and lap joint flanges is essential for any engineer working on industrial projects.

Vanstone Flange

A vanstone flange is a type of pipe flange used to connect pipes. Unlike other types of pipe flanges, a vanstone flange uses an elastomeric seal ring which is set into a groove in the outside diameter of the pipe or fitting being connected. The elastomeric seal ring creates a fluid-tight seal when properly positioned against another mating surface. This type of connection is often used in high-pressure applications because it provides superior sealing capabilities compared to other types of connections.

Lap Joint Flange

A lap joint flange is used to join two pipes together without actually welding them together. This type of connection utilizes a slip-on piece which fits over the end of one pipe and then is bolted to another mating piece which has been welded onto the second pipe so that they can be connected without having to weld them directly together. This makes it easier and faster to install than other types of connections but provides less strength or stability.

Difference Between Vanstone Flanges and Lap Joint Flanges

  • A vanstone flange is a type of pipe flange that is attached to the pipe by welding.
  • A lap joint flange is a type of pipe flange that is not attached to the pipe but instead sits on top.
  • Vanstone flanges are more expensive than lap joint flanges.
  • Lap joint flanges are easier to install than vanstone flanges.
  • Vanstone flanges provide a better seal than lap joint flanges.
  • Lap joint flanges are more versatile than vanstone flanges.

Conclusion:

Understanding the difference between vanstone flanges and lap joint flanges can be crucial for engineers or technicians who need to connect pipes for their industrial projects. Vanstone flanges use an elastomeric seal ring for a tight fit, while lap joint flanges utilize a slip-on piece which fits over one end of the pipe before being bolted onto a mating piece on the second pipe. By understanding how each connection works and its benefits, engineers can ensure they choose the right type of connection for their project’s needs.
