Pipe Pile Fabrication Process

Pipe Pile Fabrication Process

Pipe Pile Fabrication Process

(OP)
As this is relating to the design of a coastal marine structure, I put this in Marine/Ocean engineering. That's a pretty niche group, so I'll put it in over here, too:

ASTM A252 Grade 3 Pipe piles for pier and marina construction. They are commonly available in ERW, roll and weld, and spiral weld. Is there any evidence (anecdotally or through rigorous research, though research is always better) of a variation in structural performance between the methods? I imagine the failure modes would vary some, but given the variables in marine structure design I tend to keep my designs conservative and well within the elastic range. Therefore, my question is primarily with regard to elastic behavior, though any insights would be appreciated.

Thanks!

RE: Pipe Pile Fabrication Process

The weld joint strength will be larger than that of the base metal plate, so I don't see that it matters much. Note the dimensional tolerances of A252 are different than that of A500, so you may need to use a different nominal wall thickness for you analyses.
