Abstract

The invention discloses a drawing technique of a metal hosepipe for nuclear power. The drawing technique comprises the following steps that the surface of a metal wire is pretreated; after the drawing mould temperature is controlled, the metal wire is placed in a chain type drawbench for machining; lubricating agents are added for lubricating; a drawing mould is selected for machining, then powder paint is subjected to electrostatic spraying, heat transfer printing is conducted through thermosensitive transfer paper, and the surface with the drawing effect is obtained; and the metal wire with the surface with the drawing effect is manufactured into the metal hosepipe. The steps are simple, metal wire drawing is firm, the metal hosepipe has the advantages of high flexibility, retractility, bending performance, vibration resistance and bearing capacity and good corrosion resistance, meanwhile, the metal texture is high, the outer surface is attractive, and the brightness and color keeping time is long.

Description

technical field [0001] The invention relates to a wire drawing process, in particular to a wire drawing process of a metal hose for nuclear power. Background technique [0002] Metal hose is an important part of the connecting pipeline of modern industrial equipment. In complex pipeline systems, due to the limitation of space and location conditions, various difficulties in installation work are often caused: the formed pipe cannot be installed; Conversely, a makeshift tube will inevitably produce localized cold corrections. Depending on the diameter of the pipe and the specific conditions on site, the amount of cold correction ranges from a few millimeters to tens of millimeters, and some reach hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress, and the installation stress remaining in the piping system is undoubtedly extremely hidden. In the prior art, the metal hose is made of metal wire, and the production process of...
