Carbon Steel ANSI Flanges

There is no single standard flange type for every application. Available types include weld neck, slip-on, blind, lap joint, socket weld, threaded, and API flanges. Blind flanges are used for isolation and testing, while other styles support different connection and piping requirements. The appropriate selection depends on the system design, connection method, face, pressure class, and applicable specification.

The provided product information identifies ASME B16.5, ASME B16.47 Series A and B, the broader ASME B16 series, and API standards. It does not identify a specific ASTM material standard for these carbon steel flanges. Confirm the required ASTM specification, grade, documentation, dimensions, pressure class, and project requirements with the supplier before ordering.

A CS flange is a carbon steel flange used to create a bolted connection between piping components, equipment, or process sections. Carbon steel flanges are available in several types and configurations, including blind, weld neck, slip-on, threaded, socket weld, and lap joint. They may be supplied for purchase or rental, depending on the product and project application.

The listed flange products cover sizes from ½ inch through 72 inches. Rental blind flanges are listed from ½ inch to 72 inches. Availability may vary by flange type, material, face configuration, pressure class, and ownership option.
