Technical Data

A flange is a protruding rim or edge typically found on a pipe, fitting, or other structure. It comes in various shapes, sizes, and designs to accommodate different applications and requirements. Its main use is to connect two pipes or components, providing a stable, leak-proof connection within a system. Additionally, it can give access to pipelines for inspection or maintenance, support heavy equipment or structures, and facilitate the attachment of valves, fittings, or instruments.
