Large Ring Flange

A large-diameter ring flange is a type of flange that is used to connect large-diameter pipes in various industries, such as oil and gas, chemical processing, and power generation. As the name suggests, these flanges have a large diameter and are typically used for high-pressure and high-temperature applications where a strong and leak-tight connection is required.

Large-diameter ring flanges are available in a wide range of materials, including carbon steel, stainless steel, and alloy steel, and can be designed to meet various industry standards, such as ASME B16.5 or ASME B16.47. They can also be customized to meet specific application requirements.

One of the key benefits of large-diameter ring flanges is their ability to withstand high pressures and temperatures. They are designed to distribute the load and stress evenly across the flange and the piping system, which helps to prevent leaks and ensure a reliable and safe connection.

However, large-diameter ring flanges also have some disadvantages. They are relatively heavy and bulky, which can make them difficult to install and handle. They also require special equipment and expertise to install, which can add to the overall cost of the project.
