If you’ve ever had to decide between lap joint flanges and Vanstone flanges, you know that the decision can be difficult. Both types of flanges offer unique advantages depending on the application. In this blog post, we will break down the differences between lap joint flanges and Vanstone flanges so that you can determine which type is right for your project.
Lap Joint Flanges
Lap joint flanges are often used in applications where frequent dismantling is necessary. These types of flanges are connected to a stub end using two fillet welds. When the two parts are connected, they form a lap joint which consists of an inner circumference with a thin throat radius and an outer circumference with a larger radius. This allows for easy access when it comes time to dismantle or inspect the equipment. The most common type of lap joint flange is a slip-on flange, although there are other types, such as welding neck and socket welding.
Vanstone Flange
Vanstone flange is another type of flange used in applications where dismantling is not required as often as with lap joint flange. Unlike lap joints, Vanstone does not use two fillet welds to connect the two parts together; instead, a single groove cut into both parts allows them to be bolted together securely without any additional welding needed. Vanstone flanges are typically thicker than lap joints because they don’t require any additional welds for assembly; however, this also means that they may not be as easily accessible if dismantling is needed in the future. Additionally, Vanstone cannot be used in high-temperature applications due to its low heat resistance.
Difference Between Lap Joint Flanges and Vanstone Flanges
- A lap joint flange is a type of pipe flange that is used in low-pressure piping.
- A lap joint flange is attached to the pipe with two bolts that go through the flange and into the pipe.
- Lap joint flanges are often used in applications where the flange needs to be removed frequently, such as in maintenance or repair situations.
- A Vanstone flange is a type of pipe flange that is used in high-pressure piping.
- A Vanstone flange is welded to the pipe, so it cannot be removed without cutting the pipe.
- Vanstone flanges are often used in applications where the pipe needs to be strongly secured, such as in construction or industrial settings.
Conclusion:
When it comes down to deciding between lap joint and Vanstone for your project, it’s important to consider all factors at play, including accessibility, cost efficiency, and heat resistance, among others. Make sure you take all these elements into account before making your final decision so that you can choose the best option for your needs! Ultimately, both types of flanges offer advantages depending on what kind of application you’re dealing with – just make sure you do your research before committing either way!
