When rust spots appear on the surface of decorative stainless steel pipes, they should be treated in time. 2018-10-31 The long-term existence of rust spots on the surface of decorative stainless steel pipes will not only affect the appearance, but also reduce the service life due to the corrosion of the stainless steel pipe surface. Two points should be paid attention to when dealing with rust spots: 1. Do not damage the original two sides of the decorative stainless steel pipe as much as possible. If the surface is damaged, polish it smoothly; 2． The treatment should be carried out when the weather is clear and the air is relatively dry. The reason why the decorative stainless steel pipe is resistant to rust is that there is a dense layer of Cr203 on the surface, and this layer of Cr203 can be formed in contact with oxygen. When the air humidity is relatively high, there will be condensed water on the surface of the stainless steel. This condensed water makes the stainless steel and the air Of oxygen isolated. The 0r203 layer damaged by rust removal cannot be repaired in time, and the impurities in the water continue to react chemically or electrochemically with the stainless steel, so new rust spots appear on the rust-removed iron parts quickly. This is why it is required to choose to remove rust spots when the weather is relatively clear and the air is relatively dry. As long as the decorative stainless steel pipe is used and maintained correctly, it can keep bright and corrosion-free for a long time.
