A Large Diameter flange is a metal ring that is used to connect valves, pipes, pumps and other equipment that is necessary to form pipelines. The Large Diameter flange also allows people to have easy inspection, rapid modification, and easy and quick access to clean the pipes.

The ASME/ANSI B16.47 Large Diameter Steel Flanges include NPS 26 through NPS 60. This standard covers pressure ratings, temperature ratings, materials, dimensions, tolerances, marking and testing for flanges of this size with rating class designations 150, 300, 600, 900, 1500 and 2500.

The flanges are made in multiple ways. Some have lips, while others do not. Nearly every type of flange has a seal attached to it in order to preclude any type of leaks from the pipeline.

Highborn creates a significant volume of large diameter flanges for the biggest jobs in the energy and industrial fields. We can create a variety of large diameter sizes and configurations, using numerous suitable materials of construction for every application.
