What’s the difference between ANSI B16.5 and ASME B16.5 standards?

In 1973, the standard B16.5 was issued by ANSI. Before that it was an ASA standard.  The standard changed to ASME B16.5, in 1996. Before 10 years to the change, the standard ANSI & ASME consolidated and werw listed as ANSI/ASME B16.5.

So the answer is that, there is no difference between ANSI B16.5 and ASME B16.5. The ASA, ANSI and ASME are all in the same have continually filtered the B16.5 standard. We are sure that anybody is working on future improvement right now. The accurate and ongoing standard is ASME B16.5. While ANSI B16.5 is common industry language and is still referred by suppliers, manufacturers, architects and engineers. Although the ANSI B16.5 standard does not technically exist, it its understood as another way to say ASME B16.5.

The B16.5 Standard defines the following:

  1. Dimensions
  2. Tolerances
  3. Materials
  4. Markings
  5. Pressure/Temperature Ratings
  6. Pressure Testing

Devdeep distributes industrial and commercial flanges in all the materials listed below.  We work with manufacturers in the US and globally to insure the highest quality products and the fastest delivery times.

Purpose, Significance and Considerations

The ANSI B16.5 Standard Flanges are useful to join a chain of pipes, tubes or flanges together. Some flanges need to undergo high pressure. For example in oil and gas sector, flanges are required to bear high amount of physical force. Hence at Devdeep Steel Alloys the flanges are tested before they are offered for sale to a specific sector. If the pressure demand is low the flange is welded. While where the pressure required is high the flange is either bolted or threaded. The ANSI standards define the pressure PSI (pounds per second per inch) according to dimension and size of pipe flange.

The Steel flange is made from material such as stainless steel, carbon steel, nickel alloys or the kind of threaded matter used for fittings. Every flange is classified to a particular class. From these class ratings, various necessity such as bolt and nut dimensions, pressure-temperature rating, material coating and various other factors. Hence make up the flange standard corresponding to the feature.
