CAD design from a drawing (Test Loop) 01 08132019



Given the plot layout for a test-loop, a CAD design must be developed using the principles of parametric design while the fabrication and assembly methods and procedures should be simultaneously considered. The material to use in inconel, a high-temperature material with good response to corrosion.

The test-loop will be used to characterize different type of pumps (the pump will not be designed but an empty space will be at the pump location and the effect of such a

test pump will be simulated later on, for example pressure drop and flow rate).

The work fluid is molten-salt (i.e. liquid fluorides such as FLiBe, LiF–KF (50–50), LiF–NaF–KF (46.5–11.5–42), LiF–RbF (44–56)) or liquid metal (i.e. Na, NaK78, Li). Molten

salts and liquid metals can be highly corrosive and corrosion increases with temperature so a material is needed that can withstand corrosion at high temperatures. The fluid

will operate between 450-750 C. The material selected in principle is inconel.

We should highlight that fluoride salts have very low vapor pressure even at red heat, carry more heat than the same volume of water, have reasonably good heat transfer

properties, do not react violently with air or water, and are inert to some common structural metals, for which they are preferred.
