What is a Ansi Flange

- The added strength of an ANSI certified flange contributes to high performance mechanical systems, structures, and assemblies across the United States and around the world. Tested and certified to meet the specifications of the American National Standards Institute, ANSI Class Flanges carry the organization’s seal of approval for the toughest jobs.

- Originally formed in 1918, the American National Standards Institute is headquartered in Washington, DC, and is widely recognized as the American organization responsible for overseeing the national standards and conformity assessment system for products, services, processes, systems, and personnel.

- ANSI works domestically with American government agencies and organizations, as well as with international entities, to make ANSI standards useful around the world.

- Prior to the creation of ANSI, standards for engineering and equipment such as flanges were developed by the American Institute of Electrical Engineers (AIEE or IEEE), the American Society of Mechanical Engineers (ASME), the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME), the American Society of Civil Engineers (ASCE), and the American Society for Testing and Materials (ASTM International) as members of the United Engineering Society, or UES.

Ansi B16.5 Flanges

- ANSI B16.5 -1996 is the official standard for ANSI Class Pipe Flanges and Flanged Fittings, applied specifically to those made from cast or forged materials, as well as blind flanges and some reducing flanges crafted in cast, forged, or plate. It covers evaluations and standards for the following characteristics, noted in both metric and U.S. units of measure:

+ Pressure-temperature ratings, Materials, Tolerances, Dimensions, Marking, Testing, Methods of designating openings

- ANSI standard flange dimensions are designated as 150, 300, 400, 600, 900, 1500, and 2500, in sizes NPS 1/2 through NPS 24.

Types of Ansi Flanges

The standard of ANSI B16.5 flange covers blind flange (BL), slip on flange (SOP), plate flange (PL) and weld neck  flange (WN) for sizes from 10A up to 1500A diameter.

Weld flanges, weld on flanges, welding flanges, weld neck flanges, welding neck flanges, welded flanges, weldneck flange, slip on flanges, plate flanges, blind flanges, flat flanges, socket weld flanges, socket flanges, orifice flanges, threaded flanges, lap joint flanges, spectacle flanges, spectacle blind, orifice plate

Regardless of size or specification, flanges are fundamentally designed to close, cover, connect, or support pipe systems. The six common types of ANSI Class Flanges, including:

• Ansi Class Slip-On Flange

In both ring and hub style, to fit over a pipe

__________________________________________________

• Ansi Class Weld Neck Flange

Machined to match a pipe’s inside diameter and attached via welding

__________________________________________________

• Ansi Class Blind Flanges

For sealing the end or opening of a piping system or vessel

__________________________________________________

• Ansi Class Lap joint Flange

To pair with stub end fittings for applications demanding dismantling

__________________________________________________

• Ansi Class Threaded Flange

To fit pipes with external threads without the need for welding

__________________________________________________

• Ansi Class Socket-Weld Flange

To provide ideal inside flow with the use of a socket fit and top weld
