其他电镀金属相比，锌是比较便宜而又易镀覆的一种金属，属于低值防蚀电镀层，被广泛用于保护钢铁件，特别是防止大气腐蚀，并用于装饰。镀覆技术包括槽镀（或挂镀）、滚镀（适合小零件）、蓝镀、自动镀和连续镀（适合线材、带材）

Compared with other electroplated metals, zinc is cheaper and easier to be plated. It belongs to low value anti-corrosion electroplated coating. It is widely used to protect iron and steel parts, especially to prevent atmospheric corrosion, and for decoration. Plating technology includes bath plating (or hanging plating), barrel plating (suitable for small parts), blue plating, automatic plating and continuous plating (suitable for wire and strip)

下面呢，小编来给大家简单介绍一下镀锌钢管的主要目的是什么呢？

Next, let's briefly introduce the main purpose of galvanized steel pipe?

镀锌钢管的主要目的是为了防止钢铁类物体被腐蚀，提高钢铁的耐蚀性及使用寿命，同时也使产品增加装饰性的外观，钢铁随着时间的增长会被风化，水或泥土腐蚀。

The main purpose of galvanized steel pipe is to prevent steel objects from being corroded, improve the corrosion resistance and service life of steel, and also increase the decorative appearance of products. Steel will be corroded by weathering, water or soil as time goes on.

国内每年被腐蚀的钢铁差不多占整个钢铁量的十分之一，所以，为了保护钢铁或其零件的使用寿命，一般都采用镀锌钢管来将钢铁加工处理。镀锌钢管金属或构件的使用条件和使用寿命与电镀层厚度有着密切的关系。使用条件越严格和使用寿命越长，所要求的镀锌钢管层应越厚。

Corrosion of steel accounts for almost one tenth of the total amount of steel in China every year. Therefore, in order to protect the service life of steel or its parts, galvanized steel pipe is generally used to process steel. The service conditions and service life of galvanized steel pipe metal or components are closely related to the thickness of plating layer. The stricter the service conditions and the longer the service life are, the thicker the galvanized steel pipe layer is required.

不同的产品，要根据使用的具体环境(温度、湿度、降雨、大气成分等)确定预期的使用寿命的电镀层厚度，盲目的加厚会造成各种浪费。但如果厚度不足，又会达不到预期的使用寿命要求

Different products, according to the use of the specific environment (temperature, humidity, rainfall, atmospheric composition, etc.) to determine the expected service life of the plating thickness, blind thickening will cause all kinds of waste. But if the thickness is not enough, it will not reach the expected service life
