Recommended test conditions for Transition Joint Life Test Articles. [LMFBR]
Transition Joint Life Test (TJLT) is a series of high temperature creep-fatigue tests of welded pipe transition joints. The joints are made from ferritic steel (2-1/4 Cr-1 Mo) to austenistic steel (SS316) pipes of 18 inch (45.7 cm) outside diameter with or without an intermediate pipe section of Alloy 800H. ERNiCr-3 is the weld metal between 2-1/4 Cr-1 Mo and Alloy 800H or between 2-1/4 Cr-1 Mo and SS316, and weld metal 16-8-2 is used between Alloy 800H and SS316. All welds are with a nominal 0.5 inch (1.27 cm) root and a 30/sup 0/ inclusion angle. This weld geometry is selected such as to minimize the thermal stresses within practical fabrication requirements. Among the major objectives of TJLT are: (1) evaluate structural integrity of the tri-metallic transition joint design; (2) induce cracks in the test articles; and (3) evaluate the service life of the tri-metallic design and compare it to the service life of the bi-metallic design.
