By stronger, we need to define the loading conditions of the rod or pipe. The strength of a rod or pipe is typically evaluated with axial, transverse (bending), and torsion loads.

With the same diameter and the same material, a solid rod is stronger than a hollow pipe. However, with the same weight and material, the hollow pipe is stronger than a solid rod.

Because a hollow pipe is lighter than a solid rod at the same diameter, the hollow pipe would have a larger diameter in order to match weights with the solid rod and a larger diameter rod or pipe is stronger than a smaller diameter one.

What is stronger a round steel pipe or a steel hollow square bar?

A steel pipe is stronger assuming it is made of the same material and has the same thickness.


Why is hollow steel pipe stronger than solid steel?

Most of the strength of a circular section comes from the outer diameter fibers where area and inertia are the highest. So a tube is more efficient than a solid in terms of strength to weight ratio. However, if you ignore the weight benefit of a tube, the solid steel is stronger of the same diameter. If you need a certain weight, then you can make the tube stronger by increasing its diameter over a solid section of equal weight.


Can you make hollow steel pipe stronger by filling it with sand or expandable foam that turn it hard?

yes you certainly can mate


Why is a hollow shaft stronger than a solid shaft?

For a given outer diameter, the solid shaft is stronger, but it weighs more.For a given weight, the hollow shaft is stronger because it has a bigger diameter.due to less weight & less bending moment..............the resultant bending moment for a solid pipe is much larger than for a hollow one because of their weight difference


What stronge ss pipe or black pipe?

Carbon Steel pipe is stronger than stainless steel pipe as there is more iron in the carbon steel. However, the application depends on the purpose the pipe is being installed. Stainless is of course capable of being sanitized and therefore can be used for food and pharmaceutical uses. Carbon Steel (black pipe) is stronger and cheaper but not sanitary.


How much does a solid steel pipe 6 inches round by 24 inches long weight?

"Solid Steel" would not be a pipe- it would be a rod. Weight of pipe will vary depending on the thickness of the wall of the pipe.

Why does copper pipe pucker when bent?

Pipe is hollow, it needs to be solid when being bent. This can be with the aid of a solid mandrel, spring or even sand on the inside. With the pipe now a solid and if the bend radius isn't to sharp there should be no puckers when bending.
