The ANSI backing ring is an important component used in flange connections to provide additional support and stability, ensuring a reliable and tight seal. The support ring is designed to reinforce the flange assembly, especially when working with high-pressure systems. The backing ring helps prevent deformation of the flange ends during assembly, providing a secure and durable connection. The ANSI backing ring is widely used in a variety of industrial applications including pipelines, chemical processing and water treatment systems, providing a durable and efficient connection for pipe flanges.
