Corrosion set up in Vulture Petrol System. Thank you for memo. Sg.{Arthur F. Sidgreaves - MD}16/E.19.3.34. We have carried out the tests referred to in our last memo., HS{Lord Ernest Hives - Chair}/Bwg.{J. C. Bowring}5/KW.16.3.34. Three pieces of an alum casting were placed in water, petrol and water, and petrol respectively. After four days we found that the piece in water had patches of alum. hydroxide on it (as found in the Vulture system). The piece in petrol and water shewed signs of corrosion, but not to the extent of that in water alone. The third piece in petrol was absolutely free from it. There is no doubt whatsoever that the corrosion in the above system was due solely to the effects of water, quite a quantity of which the system contained. We are making arrangements for future pump castings and the insides of the petrol filter bowls to be treated with H1's anti-corrosion solution. It is however gratifying to find that Ethyl or petrol has no corrosive effect. HS{Lord Ernest Hives - Chair}/J.Bowering. | ||
