Finite element analysis and stress measurement are carried out for two typical drawing tube headers, which is a new kind of tube header without fillet weld. The material of the drawing tubes and header is SA335-P91. Two cases, normal operating condition (case 1) and cold start up condition (case 2), are analyzed. The maximum stresses are located in the inner corner of the drawing tube for one row of tube header, while the maximum stresses for both cases are located in the inner corner of the cover plate for two row of tube header. The stresses at the drawing tube for both cases meet ASME requirement for stress for both drawing tube headers. Fatigue life of the two row of drawing tube header is more than 106 cycles.
