The seamless steel pipe has a wide application in the middle of the industrial production due to its favorable performance. In order to give play to the ideal performance of the seamless steel pipe, sometimes we need to carry out zinc coating protection to the seamless steel pipe. The effective protection is a kind of way to prolong the service life of the seamless steel pipe. As for how to maintain seamless steel pipe, there are nearly two ways, hot galvanizing and electric galvanizing. The hot galvanizing includes wet process, dry process, lead and zinc process, and oxide reduction process. Viewing from the name of the electric galvanizing, the electric galvanizing adopts electrolytic way to for uniform, density as well as well-united metal on the surface of the seamless steel pipe to function as a covering layer.

The first step of how to maintain seamless steel pipe is to promote the zinc layer. The zinc layer that needs to carry out electric zinc is very smooth and compact. And it possesses well mechanical performance and favorable corrosion resistance performance at the same time, which is better than the black steel pipe. The main difference of the zinc protection methods relies on how to promote the quality of the zinc covering after using acid to wash the seamless steel pipe. And in real production, generally it is possible to use hot galvanizing due to the complex property of the technology of the electric galvanizing. It is necessary to involve in the acid of the seamless steel pipe in the middle of the manufacturing of the seamless steel pipe. However, during how to maintain seamless steel pipe, there are maybe several problems arising in the middle of the acid of the seamless steel pipe.

1. Before carrying out acid of the seamless steel pipe, it is possible to wear the protection tools well. And it is also necessary to check the scene working condition carefully, especially to check the belts of the seamless steel pipe.
2. During the acid process, it is possible to use chlorohydrin acid pickling to carry out the acid step. And generally the content of the acid is 18% to 20%.
3. And the workers need to understand the concentration and temperature of the acid well before the operation, and all these data can be measured by the professional tools.
4. And the weight of the acid should be controlled between 2 tons to 5 tons with time 5 to 15 minutes. And the time should be adjusted by the weight of the acid. And during the acid process, it is necessary to vibrate frequently. And to incline the seamless steel pipe when laying pipe under the acid tank to avoid hurting somebody.
