March 09 APPENDIX C - COOLING WATER HEAT EXCHANGER SEAWATER/FRESHWATER TYPE FG 1603877-5: PART GE098 Description 1. The heat exchanger consists of a shell, tube stack and end covers sealed by ‘O’ ring seal held in place by an end cover, which secures the seal against three faces; the body, the tube plate and the end cover. 2. Shell - Comprises an aluminium casting, fully machined to accept the tube stack. 3. Tube Stack - Comprises naval brass tube plates, between which are the tubes. Theses are punch expanded and bonded in place by soldering. The tube material is cupro-nickel. The freshwater is guided over the tube by a series if baffles arranged along the length of the tube stack. Baffles are of the radial flow type and constructed from aluminium. 4. End Covers - The end covers are manufactured in gun metal and incorporate the cooling seawater inlet and outlet connections. 5. O-Ring Seals - The material of the O-Ring seals is nitrile. Installation 1. It is important that air is kept out of the system, particularly on the fresh water side. Aerated water can cause erosion of the tubes. Heat exchange should be piped for counter flow. The cooling water inlet should be on the lower connection and outlet the upper connection. Always circulate at the recommend sea water and fresh water flows. Excessive flow can also cause corrosion and erosion.
