Stainless Art

I guess it's more engineering than art but, when observed purely as an abstract form, there could be an artistic element. I'm pretty sure whoever or whatever produced those exceptionally neat welds was primarily considering the functional integrity of the join (at least I hope that was the case!). 
Too cold to work outside today, hence decided to examine the pipework indoors. 
At least it's been another bright day and, according to the forecast, the cold spell will be coming to an end in the next few days.
