Compressive Strength of Steel Pipe 1

[amarks]

Does anybody know the material properties of various types of steel piping? Looking for the yield stresses for seamless carbon or stainless pipes.

Looking for this to calculate hoop stress. Specifically using the hoop stress in a drum barrel in DnV's 2.22 (JUNE 2013: PAGE 51) reference.

Thanks,
Alex

Allowable tensile stress are given in your design code.
Also the formulas yo use in the calculation.

There's not really a design code that I am following for this project (besides getting the formula for hoop stress from that DnV reference, which doesn't give you the tensile stress for the drum barrel). It just says that it can't be more than 85% of the yield.

Yield for A53 or A106 grade B carbon steel pipe is 35,000 psi. A312 TP304 or TP316 stainless is 20,000 psi yield. These are minimums per the associated ASME spec.

If you do not find allowable stresses in the code (DNV 2.22 is lifting devices), maybe you should be posting in a different forum. This is pipe for fluid applications. We are typically not well versed in lifting device design. At least not me.

Think this is related to the OPs other post which is about winch drums, hence external compressive buckling forces.

1503-44 - the allowable stress is 85% of the material yield. I was wondering if anybody in the "Pipelines, Piping, and Fluid Mechanics Forum" might know something about piping material properties. The end goal was to try and figure out the compressive strength of a piece of pipe that I am planning to use for a winch drum barrel.

LittleInch- That is correct. I was looking at the design of the project and figured why not explore all my resources to try and get the answers I need?

you can, but the normal mode her eis to resist internal pressure from a fluid, not external force from a winch drum, which is rather odd in pipeline and piping terms.

External pressure / compression is a bit different from normal pipe yield stuff so I'm really not sure if the SMYS applies in compression in the same way. I guess buckling due to external pressure is the closest you would get, but the force is not uniform, especially when first reeling it, so its all rather odd for piping forum. That's all.

LittleInch - That makes sense, appreciate your example.

Cranes and lifts are really not in my experience envelop.
I'd be worried about snapping cable forces and such.
