Description of ASME B16.5 Carbon Steel Lap Joint Flanges:
Lap Joint Flanges, also known as loose flanges or Van Stone flanges, are a type of pipe flange that offers several unique features and advantages. They are widely used in piping systems for various industrial applications.
The design of Lap Joint Flanges consists of two separate components: the Stub End and the backing flange. The Stub End is a short piece of pipe with a slightly larger outer diameter than the pipe it connects to. It has a flat face and is welded to the pipe. The backing flange, on the other hand, is a ring-shaped flange with a flat face and a protruding lip or collar.
One notable feature of Lap Joint Flanges is their ability to rotate freely on the Stub End. The backing flange is not welded to the pipe, allowing it to rotate independently. This rotation capability makes aligning the bolt holes during installation and removal much easier, simplifying the assembly process.
Lap Joint Flanges are often used in situations where frequent dismantling of the piping system is required for inspection, maintenance, or repair purposes. The ability to separate the Stub End and backing flange without disturbing the pipe allows for quick and convenient access to the joint, minimizing downtime.
Another advantage of Lap Joint Flanges is their cost-effectiveness. By using a costly corrosion-resistant alloy only for the Stub End while employing a less expensive material, such as carbon steel, for the backing flange, overall costs can be reduced without compromising the required corrosion resistance.
However, it's important to note that Lap Joint Flanges have limitations. They are typically recommended for low-pressure applications where the loads exerted on the flange connection are relatively low. The sealing capability of Lap Joint Flanges is also limited, relying on gaskets placed between the Stub End and the backing flange to provide a seal.
Despite these limitations, Lap Joint Flanges remain a popular choice in various industries due to their easy installation, rotational flexibility, cost-effectiveness, and suitability for applications that require frequent dismantling.
