ABSTRACT:
According to one aspect of the present disclosure, 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. According to another aspect of the present disclosure, 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.
