A method for making a tube is described in which a multi-layer billet is extruded to provide a tube having a wall comprising an inner layer metallurgically bonded to an outer layer.

Method for making corrosion resistant fluid conducting parts

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.

Zirconium or zirconium alloy components of a cylindrical shape are cleaned with an ice blasting process to produce a defect-free bondline in multi-layered tubing suitable for nuclear fuel cladding and the chemical processing industry. The ice blasting process improves the integrity of the metallurgical bond by removing foreign contamination that can initiate non-bonding defects.
