When it comes to pipe fittings, lap joint flanges are an indispensable component. These flanges are designed to slide over the pipe and are secured in place using a lap joint stub end. That's why they're also known as lap-joint stub-end flanges.
Lap joint flanges are often used in applications where the pipe needs to be disconnected frequently, such as in pipelines that need regular maintenance or repair. They're also used in systems that require alignment adjustments.
What Are Lap Joint Flanges Used For?
Lap joint flanges are most commonly used in applications where the pipe needs to be disconnected often, such as in systems that require regular maintenance and repair work. They're also used in applications where alignment adjustments are necessary.
Another unique feature of lap joint flanges is their rotational capacity. This allows them to be easily aligned with other components in the system, making them ideal for use in systems with misaligned pipes.
Lap joint flanges are also used in applications where the pipe material is not compatible with the flange material. In such scenarios, the lap joint flange can be made of a different material than the pipe, enabling them to be joined easily.
Lap joint flanges are also known as Van Stone flanges, a reference to the co-founder of the company that first developed them in the 1960s.
Types of Lap Joint Flanges
Lap joint flanges are available in several types, each with its unique features and characteristics. Here are the most common types of lap joint flanges:
Standard Lap Joint Flanges: These flanges are the most common type of lap joint flange and are available in a range of materials, including stainless steel, PVC, and brass.
Raised Face Lap Joint Flanges: These flanges feature a raised face on the flange to create a sealing surface. They are often used in high-pressure applications.
Flat Face Lap Joint Flanges: These flanges have a flat face, making them easy to align for welding. They're commonly used in low-pressure applications.
Ring-Type Joint Lap Joint Flanges: These flanges feature a metal ring that sits inside the flange channel, creating a highly effective seal. They're commonly used in high-pressure and high-temperature applications.
Table H Flanges
Table H Flanges are a specific type of lap joint flange. These flanges are designed to meet the pressure and temperature ratings of ASME/ANSI B16.5 and ASME/ANSI B16.47 standards.
Table H Flanges are typically used in high-pressure and high-temperature applications, such as in the oil and gas industry, chemical processing plants, and power generation facilities.
Conclusion
In conclusion, lap joint flanges are an essential component in pipe fittings, enabling easy disconnection and realignment. They come in various types, each with its unique features and characteristics. Lap joint flanges are also known as Van Stone flanges and are often used in applications requiring a rotating capacity, easy alignment, and material compatibility.
Table H Flanges, a specific type of lap joint flange, are designed to meet the rigorous pressure and temperature requirements of high-pressure industries such as oil and gas, chemical processing, and power generation.
When it comes to pipe fittings, lap joint flanges, including Table H flanges, are a crucial and reliable solution for many applications.
