This specification covers the material, dimensions, and construction of a water trap for diesel exhaust. The diesel exhaust water trap system shall consist of a tank and baffles manufactured from a nickel-chromium-molybdenum-columbium alloy, with gaskets made of nonmetallic materials. A minimum of three baffles shall be installed. The traps shall withstand the maximum temperatures specified, be free of paint, and be so designed such as to prevent sea backwash from entering the diesel exhaust system. The trap and piping systems shall prevent dirt accumulation, with the welding being of small, even beading, free of slag and splatter. Pneumatic proof testing of each trap shall be performed with no visible seam leakage and shall conform to the requirements specified.
