I had some seamless 3/4" steel tubing that I was partially successfully in
bending. into a desired shape by tightly packing it with fine sand and
heating it with oxyacetylene. This is for a turbocharger oil drain pipe and
follow a convoluted path between the manifold piles towards the bottom of the
block. I was not thrilled wit the results. The pipe swilled in couple of
places and blistered in others because I didn't have a proper heating
attachment. I was using a cutting head without applying oxygen. I will be
getting rosebud attachment shortly. I need to practice some more and would
like to use seam welded tubing instead. My concern is will the seam split
during the bending process? Since there are number of bend in different
planes it is difficult to predict where the seam will end up. In use this
pipe has no internal pressure. It just has to drain oil.
I have seen regular 2" steel pipe bent hot into a bunch of crazy shapes to make heating coils for double-bottom oil tankers. No split, ever. I really doubt those welds will split. Try it.
