Thin wall SCH 40 pipe welded to a thicker plate

[Astudy]

Hi all,
What is the design considerations regarding the punching force on a SCH 40 pipe with a thin wall thickness(0.15in) when welding a thicker plate (3/8in)? AISC has lots of design information on round HSS, but not pipe. Can I apply the same connection design concept to pipe? Does the maximum plate thickness formula(AISC Manual K1-3)applicable to a pipe?

I am also looking for an example of this design. Thank you.

That must be a pretty small diameter pipe section..2"? 1.5"? Provide a sketch and more background on how the connection will be loaded so it's more clear what you're trying to do.

Generally, yes you can apply the same connection design principles to pipe as round HSS. The major differences are the yield and rupture strength parameters associated with the most common material specs for the two types of section, but A53 Grade B meets the ductility (Fy/Fu) requirements in chapter K. The other difference is that pipe has to be pressure tested, which usually makes it more expensive than round HSS.
