| To Mr. Swift from BY.{R.W. Bailey - Chief Engineer} C. to EH. c. to EFC. October 25th. 1918. BY16/P251018. [Crossed out: X 3388.] RE CYLINDER JACKET CORROSION. You will remember that I had some cylinders fitted with jackets treated to prevent corrosion. Mr. Hives reports very favourably on these, stating that after 60 to 70 hours there are no signs of carbon [handwritten correction: corrosion] being set up. He now asks for 12 cylinders treated similarly. The treatment in question was as follows:- Before making up the cylinder and jackets the outside of the cylinder was well sand blasted, also the inside of the jacket. In the case of the cylinder the treatment included the inlet bends, which were, of course, welded to the cylinder before sand blasting the latter - the jackets were then welded on in the usual way. The next operation was to fill up the jackets with sulphite solution, which was kept, I believe, at the usual temperature at which we treat spanners, for the same length of time that the spanners are imersed in the liquid. The solution was then poured out of the cylinder and the latter allowed to stand. Kindly arrange to let Mr. Hives have 12 cylinders treated in this way as soon as possible. BY.{R.W.
