Top 10 Flange Factory in the world

Introduction to Flange

A flange is a forged or cast ring of steel designed to connect sections of pipe, to valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. They are widely used in various industries such as oil and gas, chemical, power generation, and water treatment due to their reliable connection and ease of installation and maintenance.
