[0002] Seamless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils. When the steel pipe is electroplated, the steel pipe is placed in an electroplating bath or electroplating pot for electroplating.

[0003] Most of the existing seamless steel pipe electroplating equipment adopts the hanging plating method. Usually, the seamless steel pipe to be electroplated is hung on a hook-like object and then placed in an electroplating box for electroplating. However, when electroplating the seamless steel pipe in this way, the hook and the seamless steel pipe are in contact at the same position for a long time, resulting in poor electroplating effect at the contact position and reduced electroplating quality.
