Abstract

The invention discloses a finishing method of a zirconium alloy pipe and belongs to the technical field of metal material finish machining. The finishing method comprises the steps that the zirconiumalloy pipe is straightened, and a straightened zirconium alloy pipe is obtained; the straightened zirconium alloy pipe is subjected to inner surface sand blasting treatment, and a sand-blasted zirconium alloy pipe is obtained; the sand-blasted zirconium alloy pipe is placed on a cut-off machine to be subjected to fixed length cutting treatment, the inner surface of the zirconium alloy pipe subjected to fixed length cutting treatment is cleaned, and thus a cleaned zirconium alloy pipe is obtained; and the cleaned zirconium alloy pipe is polished or subjected to internal flowing acid-pickling treatment, and thus a finished zirconium alloy pipe finished product is obtained. The zirconium alloy pipe finished through the technique meets the required precision requirement, the using requirementsof a nuclear reactor are met, the size performance, the surface state and the in-reactor using performance of the zirconium alloy pipe all meet the domestic technological requirements of products, and the zirconium alloy pipe can put into service after passing subsequent nondestructive detection and appearance detection.

Description

Technical field [0001] The invention belongs to the technical field of metal material finishing, and relates to a finishing method of zirconium alloy pipes. Background technique [0002] Introduction of existing technology [0003] Zirconium alloy is a widely used structural material in nuclear reactors. Its main function is UO 2 Cladding, fuel assembly structural support and fuel rod end sealing, etc. Nuclear-grade zirconium material technology includes manufacturing technology from nuclear-grade sponge zirconium to tubes, bars and strips for nuclear fuel assemblies. So far, my country has not developed practical high-performance zirconium alloy fuel assembly materials with completely independent intellectual property rights, and still heavily relies on foreign imports. [0004] In order to solve the problem of localization of nuclear-grade zirconium materials, we have developed a new type of zirconium alloy comparable to the mature and used internationally for many years of Ameri...
