Title:
装置中の腐食した流体伝導部品を溶接によって交換する方法及びそれによって得られる部品
Document Type and Number:
Japanese Patent JP5922729
Kind Code:
B2
Abstract:
A part for an article of equipment includes a fluid conducting first region including a corrosion resistant first material, and a fluid conducting second region including a second material. The first region and the second region are either directly or indirectly joined by solid state welding to form a unitary fluid conducting part. A method for replacing at least one fluid conducting part of an article of equipment is disclosed wherein a replacement part is provided that includes a fluid conducting first region including a corrosion resistant first material, and a fluid conducting second region including a second material. The second material is substantially identical to the material of a region of the equipment on which the replacement part is mounted. The first and second regions are either directly or indirectly joined by solid state welding to form a unitary fluid conducting replacement part. The replacement part is secured to the article of equipment by a process comprising fusion welding the second material of the second region of the replacement part to the substantially identical material of the mounting region of the article of equipment.
