AI Thread Summary
The discussion focuses on the differences between flange standards BS EN 1092-2 and BS 4504, 4505, 4722, and 4772. While BS EN 1092-2 may replace certain aspects of BS 4504, a detailed comparison of dimensions and specifications is necessary to confirm compatibility. The British Standards Institute is transitioning towards adopting EN standards, which may influence future flange specifications. Users are encouraged to access both standards for a thorough understanding, and resources are available online for reference. Understanding these differences is crucial for ensuring proper flange selection in engineering applications.

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?

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.

It is good!
 
Hello there ,

Can you please help me in knowing the difference between ANSI B 16.5, 150 Flange and EN1092-2 Flange ? Please help.
 

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
