In the production of the manufacturing of seamless steel pipes, the steel pipe pickling process is involved in. For the staff, what should be paid attention to during the pickling process of a seamless steel pipe?

First and foremost, you must wear good labor protection supplies before pickling. The working environment on the site should also be checked in detail.

Second, hydrochloric acid pickling is mainly adopted when pickling. The best content of hydrochloric acid is 18% to 20%.

Third, the staff also need to understand the concentration and temperature of the acid and the tonnage of the pickling pipes of the tank before the operation. These can be detected by using professional measuring equipment.

Fourth, the weight of the pickled seamless steel pipe can be best controlled between two and five tons each time, and the time is controlled within five to fifteen minutes. The time needs to be adjusted according to the amount of weight. In the process of pickling, the seamless steel pipe also needs frequent vibration. When the seamless steel pipe is put under the acid tank, it should be tilted to prevent people from injury of the hydrochloric acid.
