Contd;-

round the flanges, or the vertical seams, the most frequent place for laekages is in the joint where the vertical seam joins the weld round the valve band. This is a place we get most leaks on R.R. cylinders. We have thought it was due to the fact that the jackets as a rule do not fit very well at that point. We shall be able to say more when we have tested the cylinders which have been re-welded. Except for the poor welding we consider the American cylinders a very good job.

EH.
