Abstract

The invention discloses a production process of an air-conditioner condenser pipe. The production process comprises the following steps of preparing materials, rolling, drawing, straightening, washing, annealing, detecting flaws and putting in storage. According to the process, existing equipment is employed for production, special equipment is not needed so that the air-conditioner condenser pipe can be produced in large scale; compared with a conventional production process, the process is high in product yield and low in production cost after being employed for production, the material waste is reduced, the produced condenser pipe is high in quality and the competitiveness of an enterprise is improved.

Description

technical field [0001] The invention relates to the technical field of condensation pipes, in particular to a preparation process of air-conditioning condensation pipes. Background technique [0002] China's copper demand continues to increase, and this increase is largely resource-consuming. The best way to solve this dilemma is to adopt less and no cutting process, actively research and develop new varieties of copper materials, and continuously improve product quality is an important measure to meet the development of the national economy, reduce the import of high-precision copper materials, and enhance the competitiveness of the international market. However, the traditional method of producing copper condensing pipes is the semi-continuous casting-extrusion-rolling method, which has complex technological process, low yield and high energy consumption, and high production cost. Therefore, an air-conditioning condensing pipe is proposed. Tube manufacturing process. Co...
