RESULTS OF A SAPL THERMAL STRESS TEST ON A STAINLESS STEEL TUBE
Technical Report
·
OSTI ID:4352374
The effect of a repeating or cycling thermal stress on a thin wall stainless steel tube was determined. The apparatus used was essentially a paralleled flow single pass concentric tube heat exchanger with hot Na flowing through the inside of the inner tube and cold Na flowing in the annulus between the inner and outer tubes. It is concluded that the experimental values of Na film coefficients are about 35% lower than predicted but are of the right order of magnitude. A thermal stress varied from zero to 32,400 psi 132 times is insufficient to cause a crack or failure in a stainless steel tube at an average temperatare of 540 deg F. (L.T.W.)
