Common industry association flanges used in the oil and gas industry are American Society of Mechanical Engineers (ASME) B16.47/ American National Standards Institute (ANSI) B16.5. These institutions assist in the development and implementation of industry uniformity to ensure the minimum requirements used for safe application. The committees provide standards covering pressure-temperature ratings, materials, dimensions, tolerances, markings, and methods of designating openings for pipe flange and fittings.
Coastal Flange manufactures a wide variety of pipe flanges including weld necks, slip-ons, and blinds in addition to custom designs for special application. Pressure classes for the oil and gas industry are determined based on the pressure and temperature of the application. Pressure ratings include class: 150, 300, 400, 600, 900, 1500, and 2500 in carbon, stainless-steel, and alloy.
