| 48230 HS.{Lord Ernest Hives - Chair} C. HC E.A.C. EXHAUST SYSTEM. In regard to the corrosion of the exhaust pipes where lagged with asbestos, we have arranged, as you will have seen, to have some pipes calorized as an experiment, leaving the ends free of calorizing where they have to be brazed, as it is impossible for us to have the parts treated by Calorizing after brazing, owing to the high temperature of calorizing. We have, in addition, approached Messrs Firths who inform us that they can produce Stainless Steel tubes of the dimensions we require, and I therefore suggest that we obtain some lengths of tubes in Stainless Steel, and hand same over to the Experimental Dept. to try and bend them and build them up. Neither Firths nor the Chesterfield Tube Company have facilities for tube bending. They do not anticipate any difficulty, nor do I myself, in this connection, as the tubes can be worked hot. If you are in agreement with the proposal, I would like to order some tube and get the experiment tried out, as obviously rustless steel tube would be the cleanest and easiest way out of the difficulty.
