Explosive welding device for joint of zirconium-alloy transition tube and stainless-steel transition tube

Abstract

The invention belongs to the technical field of explosive welding, and particularly relates to an explosive welding device for the joint of a zirconium-alloy transition tube and a stainless-steel transition tube. The explosive welding device comprises a detonator, explosive, a zirconium-alloy compound tube, a stainless-steel base tube, a mold, a bracket, supporting legs and a non-metallic conical body, wherein the supporting legs are symmetrically arranged under the bracket; the bracket is placed on the ground through the supporting legs under the bracket; the mold is arranged on the bracket; the mold is in the shape of a hollow round table; the stainless-steel base tube is mounted in the mold in a sleeving manner; the zirconium-alloy compound tube is coaxially arranged in the stainless-steel base tube; a gap is formed between the inner surface of the stainless-steel base tube and the outer surface of the zirconium-alloy compound tube; the non-metallic conical body is arranged in the zirconium-alloy compound tube; the explosive is stuffed between the non-metallic conical body and the zirconium-alloy compound tube; the detonator is placed on the explosive. Through the adoption of the explosive welding device disclosed by the invention, the production quality of joints of zirconium-alloy transition tubes and stainless-steel transition tubes is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of explosive welding, in particular to an explosive welding device for a pick alloy and stainless steel transition pipe joint. Background technique [0002] Zirconium alloys have good corrosion resistance, moderate mechanical properties, low atomic thermal neutron absorption cross section in high temperature and high pressure water and steam at 300-400 ° C, and have good compatibility with nuclear fuel, so they can be used as water cooling The core structural material of nuclear reactors (fuel cladding, pressure tubes, brackets and tunnel tubes), which is the main use of zirconium alloys. Moreover, zirconium has excellent corrosion resistance to various acids (such as hydrochloric acid, nitric acid, sulfuric acid and acetic acid), alkali and salt, so zirconium alloys are also used to make corrosion-resistant parts and pharmaceutical devices. Pick alloy and stainless steel transition pipe joints are special ...
