The end portion of the first pipe is welded to the end portion of the second pipe to seal the joint between the first pipe and the second pipe. The first pipe has an outwardly-extending, buckle-inducing deformation that is spaced apart from the pipe joint. A crest height of the deformation is 500% or less of the first pipe wall thickness.
