Abstract

The invention discloses a processing method of a corrosion-resistant copper pipe. The method comprises the following steps of (1) pretreating the surface of the copper pipe; (2) soaking the copper pipe subjected to surface pretreatment in a tin-containing solution for a period of time; (3) carrying out electroplating treatment on the copper pipe treated in step (2); and (4) cleaning, neutralizing, secondarily cleaning and drying the electroplated copper pipe. The working procedures in the steps belongs to conventional treatment in the field. The process method is simple and convenient, and the produced copper pipe is good in corrosion resistance.

Description

technical field [0001] The invention relates to a copper pipe, in particular to a tinned inner wall copper pipe with high corrosion resistance and a processing method thereof. Background technique [0002] With the development of the economy, the scope of application of copper pipes is becoming wider and wider, especially for products such as gas water heaters, which have a huge demand for the use of copper pipes; Although copper tubes have good corrosion resistance and are not easy to oxidize, most of the existing copper tubes are treated around the outside of the tube to achieve anti-corrosion; and the inner cavity of the tube is seldom treated specially, which will lead to the inner cavity of the copper tube. Corrosion resistance is poor, which brings a lot of inconvenience to the users and users of copper pipes. Therefore, there is an urgent need for a copper pipe with high corrosion resistance on the market, especially a copper pipe with better corrosion resistance in ...
