An instrumented loop of stainless steel in which molten chloried salt is transported has been constructed and operated. The purposes of operating this equipment are to investigate thd feasibility of transporting liquid salt with a pressurizing cylinder, to test the equipment and various instruments, and to determine whether pressurized salt loops are suitable for laboratory use. The principal components of the loop include a high temperature valve, vessel with furnace, and an orifice flow meter. The high temperature valve is a commercially available, needle valve. The orifice flowmeter is also a commercial item. Most of the connections in the loop are welded. A material test is conducted to evaluate the suitability of various materials of construction for process applications. Such items as transport lines, agitators, and associated equipment are included. Corrocion rates of various materials are obtained.
