ANSI B16.5 Class 2500 Flanges | Welding Neck

The ANSI B16.5 2500 Weld Neck Flange is a type of flange specifically used in industries that allow high pressure and high-temperature, such as oil exploration and chemical production in pipeline systems. It can withstand a pressure of 2500 pounds force per square inch (PSIG) as per the ANSI (American National Standards Institute) standards.

ANSI B16.5 Class 2500 Flanges | Lap Joint

ANSI B16.5 Class 2500 Lap Joint Flanges conform to the pressure class of 2500 pounds-force per square inch (PSIG) as specified by the ANSI (American National Standards Institute) standards. These flanges consist of two stub ends and backing flange, typically used to connect different sections of pipe.

ANSI B16.5 Flanges

ANSI B16.5 is a standard published by the American Society of Mechanical Engineers (ASME), officially known as “Pipe Flanges and Flanged Fittings.” It is applicable to pipe flanges and flanged fittings made from cast or forged materials. This standard covers the assessment and specifications of pipe flanges and flanged fittings characteristics for NPS 1/2 to NPS 24, represented in both metric and U.S. customary units: Pressure-temperature ratings, Materials, Dimensions, Tolerances, Marking, Testing, Methods of designating openings.

  • ansiasmeb16.5

The ANSI standard flange sizes include classes 150, 300, 400, 600, 900, 1500, and 2500. The standard also includes requirements and recommendations for flange bolting, flange gaskets, and flange joints.

FAQ

Any butt-weld fitting or weld-neck flange can be directly welded to any other butt-weld fitting or weld-neck flange without the need for any extra piece of pipe (Pup piece) between them.

The Weld Neck Flange offers increased strength under higher pressures, subzero or elevated temperatures that cause line expansion or retraction, or other variable forces. The Slip On Flange is connected to the pipe by two welds, one on the back side of the Flange and one on the inside of the Flange.

Weld Neck Flanges, It gives the highest level of joint integrity as it is butt-welded with a pipe. These types of flanges are used in high-pressure and temperature application.
