RE: Spectacle Blind weight

Welcome back Barbara

is everyone a bit testy at the moment or is it just my highly refined sensitivity? It the equinox here which means big winds, and big winds mean bad tempers.
Personally I never trust my calculations, and always put my faith in total strangers. I expect you do the same in the nuclear power industry. That way I can never be at fault.
I noticed you all assume it is a carbon steel flange. Further I note you provided mass when weight was clearly asked for.

Because this sort of thing is happening frequently, I googled "weights of spectacle flanges" and got back
http://www.texasflange.com/Catalog.pdf . Elapsed time 30 seconds.Yes it has weights of spectacle blinds. And yes I would check-calculate the weight from the dimensions. I am a bit slack though; work out the plan area in sqm, multiply by mm thickness and then multiply by 8, as 1 sqm of steel 1mm thick weighs a bit less than 8kg (oops, now see what you made me do) sorry 78.48N, Chris.

I do hope this group is not being used as a sort of free internet search service.

Better get back to working for a living.

Cheers

Steve

Hi Rathish,

Its fair enough that you have asked the question as requested and you have received two similar answers. Do you think that a calculation based on known dimensions and density is more trustworthy than a number somebody gave you on the internet? I know which option I would accept if I was checking your analysis!

Barbara
