What is the difference between asme b16.5 and ansi b16.5
ASME B16. 5 and ANSI B16. 5 refer to the same documents since ASME and ANSI work hand in hand in preparing and administering standards. However, there are some historical and technical distinctions to be aware of:However, there are some historical and technical distinctions to be aware of:
Origin and History:
Standard ASME B16.5, developed by the American Society of Mechanical Engineers (ASME), addresses Pipe Flanges and flanged fittings.
ANSI B16. 5: ANSI B16. 5 is another obsolete name for it, which reflects the history of ASME’s connection with ANSI. ANSI authorized ASME to establish and update some of the requirements on their behalf establishing, for instance, B16. 5. Therefore, ANSI B16. 5 and ASME B16. This means that five of them refer to the same standard that is why they must be harmonized.
Scope:
ASME B16. 5: ASME B16. 5 deals with the specifications of the pipe flanges and flanged fittings with regards to dimensions, materials and pressure-temperature ratings. It entails the different flange categories like weld neck, slip-on, socket weld, blind, and lap joint flanges.
ANSI B16. 5: Recall that ANSI B16. 5 is in fact similar to asme b16. 5. However, it also over the same scope of pipe flanges and flanged fittings.
International Adoption:
ANSI is sometimes used in the broader context meaning that it is an American national standard that has been incorporated internationally. On this background, ASME B16. 5 is being commonly termed as an ANSI standard when implemented in international environments.
Updates and Revisions:
For time and time again, ASME B16 has developed into a focal point in the designing of pipelines, valves, and similar structures. 5 has gone through various revisions to make adjustments based the changes that may occur in the industries’ practices, materials, and technologies. These changes are conducted by the ASME committees which work on the particular standard.
In summary, ASME B16. 5 and ANSI B16. 5 relates to the same standard on pipe flanges and flanged fittings essentially. The terminologies highlighted above are indicative of the historic connection between ASME and ANSI; however, ASME is the main society most involved in the creation and administration of this standard. Users should therefore consult to the latest edition of ASME B16. 5 depending on their needs because the editors work on its updates periodically to cover the contemporary trends and norms.
ASME B16.34 vs ASME B16.5
ASME B16. 34 and ASME B16. 5 are codes that have been created by the American Society of Mechanical Engineers (ASME) but they different in the way they address the matter of piping systems. Below are the results for the comparison of ASME B16. 34 and ASME B16. 5:
ASME B16. 34:
Scope: ASME B16. 34 is the standard which deals with valves particularly the steel valves, the flanged and butt-welding end. It gives requirements for design, material, fabrication, examination and certification of the steel valves to be used in industries.

Pressure-Temperature Ratings: ASME B16. 34 gives pressure-temperature ratings for valves whereby the user is in a position to make the right purchase on the type of valve suitable for a certain pressure and temperature condition. These ratings are very essential since they may be used in the right manipulation of the valve in different pressure and temperature conditions.
Materials: According to the standard, there are provisions on aspects of valves that are in relation to the material that is to be used in construction of a valve such as body material, trim material, gasket material, and the bolting material.
Testing: ASME B16. 34 defines valve testing; this may include the hydrostatic test, pneumatic test or any other forms of test that will prove the fitness of the valves.
Certification and Documentation: The standard provided for documentation practices like certificates, test reports, and material tracking related to the valves’ manufacture.
ASME B16. 5:
Scope: ASME B16. 5 relates to a standard that is concerned with pipes and their joining devices commonly known as flanges and fittings. It provides the specifications on flanges in terms of dimensions, make up materials, and pressure /temperature ratings for the piping systems.
Flanges: This standard is applied on flanges of different classes including weld neck, slip-on, socket weld, blind, and lap joint among others. It focuses on how to proceed in the process of searching for flanges that could be relevant to a specific requirement regarding piping.
Pressure-Temperature Ratings: ASME B16. 5 specifies pressure-temperature ratings for flanges, helping users select flanges that Pressure-Temperature Ratings: Of The Ansi B16. 5 provides pressure-temperature ratings of flange which enables the user to select the right flange for the right pressure and temperature class of the piping system.
Materials: The following is the information that the standard also specifies the material of construction of flanges and flanged fittings so as to be compatible with the material of construction of piping system.
Flange Facings: ASME B16. 5 has general and very necessary requirements for flange facings that are very critical for sealing and gasket interface.
Testing: While ASME B16. ASME B31. 5 does not have the specific test procedures; instead, it directs the reader to other codes of the ASME, for example, ASME B16. 34 for valve testing.
In summary, ASME B16. 34 is organized about valves used in processes and prescribes exact specifications concerning design, material, manufacturing, testing, and registration. ASME B16. 5 on the other hand deals with pipe flanges and flanged fittings, within this standard provides the dimensions, material, pressure temperature ratings and flange facings. The two standards are correlated in the fact that valves and flanges are two key parts of the piping systems and as such should have certain characteristics of the standards.
what is the difference between ASME B16.5 and ANSI B16.5
