PIPELINE WELDING PART REINFORCEMENT STRUCTURE AND BOILER PLANT INCLUDING THE SAME AND PIPELINE WELDING PART REINFORCEMENT METHOD

摘要

To provide a pipeline welding part reinforcement structure which can reinforce a welding part without affecting residual life of the welding part of a pipeline.SOLUTION: A pipeline welding part reinforcement structure 1 includes: a welding part W1 which is formed on a pipeline 2 so as to extend in a circumferential direction; reinforcement ribs 3 which extend in a direction intersecting with the circumferential direction while sandwiching the welding part W1 and are formed so as not to contact with the welding part W1; and support plates 7 which are fixed to both end part sides of the reinforcement ribs 3 and fixed to the pipeline 2 at a position spaced away from the welding part W1 by welding.SELECTED DRAWING: Figure 1
