Flange Standards: Comparing BS EN 1092-2 to BS 4504, 4505, 4722 & 4772

[danapillai]

i just wanted to know the difference of the flanges to BS EN 1092-2, BS 4504, BS 4505, BS 4722 and BS 4772.
will the flanges to BS EN 1092-2 and BS 4504 match?

BS EN 1092-2 and BS 4504 match?

They might, but one should try to obtain both specs and do a comparison of dimensions and bases.

According to http://www.standardsdirect.org/standards/standards5/StandardsCatalogue24_view_8556.html

BS EN 1092-2:1997 replaces BS 4504:Part 3:Section 3.2:1989.

If one works for a company, the library should have both copies or a document that compares standards.

However it appears that the British Standards Institute are adopting the EN standards.

I can provide an objective analysis of the differences between the flange standards mentioned. The main difference between BS EN 1092-2 and the other BS standards (4504, 4505, 4722, and 4772) is that BS EN 1092-2 is a European standard, while the others are British standards. This means that the requirements and specifications for flanges in BS EN 1092-2 may differ slightly from those in the British standards.

In terms of specific differences, BS EN 1092-2 has a wider range of pressure ratings and sizes compared to the other BS standards. It also includes additional design requirements for flanges used in cryogenic applications. On the other hand, the British standards have specific requirements for flanges used in specific industries, such as BS 4504 for flanges used in waterworks and BS 4505 for flanges used in the oil and gas industry.

In terms of compatibility, it is possible for flanges to BS EN 1092-2 and BS 4504 to match, as both standards follow the same design principles and use similar materials. However, it is important to carefully check the specifications and ratings of the flanges to ensure a proper match.

In conclusion, while there may be some differences between the flange standards mentioned, they all serve the same purpose of providing guidelines for the design and manufacture of flanges. It is important to carefully review the specific requirements of each standard to ensure the proper selection and use of flanges in different applications.
