KG / mm square and loading
KG / mm square and loading
(OP)
Hi,
I have been informed by the bracket supplier of a safe load figure of 72.12 kg/mm sq for 8mm threaded rod.
I only know my pipe weights in kg / metre.
How do i calculate if the 72.12 kg/mm sq is of sufficient strength to hang the pipe. Is it simply 72.12 x the cross section of 8mm?
Thanks
Lee

For this case you would multiply the 72.12kg/mm^2 by (8mm)^2 x pi / 4 = 3625kg.
That's what the threaded rod will hold. Now take your pipe length and multiply by its weight in kg/m to get its total weight at that bracket. If it's less than 3625kg, it's OK.
If you "heard" it on the internet, it's guilty until proven innocent. - DCS

i think the load you have is the maximum sustainable load, so you could always test one to see.

I think these are hangers loaded only in tension.
