calculation on it.
You could do Euler-Bernoulli - the familiar beam calc. yourself

Second Moment of Area

Section modulus

Section Moment capacity

Load-bearing capacity

You could also get the expected deflection - which can be had when you
know the Second Moment of Area.

what a nerd fest. It's black gas pipe as used in the US. Does it have
guaranteed structural properties? no. Will a 5 foot piece hold up skillets
arranged like clothing in a closet on hangers? yes, it will.
