Precautions for pickling of seamless tubes:
The first thing to pay attention to is the acid content in the pickling process used for rust removal. Through practice, it is found that the acid content of 18% is the best. Although the seamless steel pipe can be placed in a humid environment, in order to prevent the electrolyte from adhering to the surface of the seamless steel pipe, friends also need to place it in a dry environment.
The maintenance of seamless steel pipes in the later stage is actually quite important, especially after leaving the factory. The most important step is pickling. Because it is processed by chemical elements, you need to pay attention to your own safety in terms of safety protection. In particular, the staff need to wear the necessary protective equipment, and the same environment should also be carefully checked. Don't just care about one point, check it several times to see if the protective sling of the steel pipe is firm. After this series of checks are correct, the work can be carried out.
Pickling, there is no doubt that the raw material is mainly acid, but the content of acid should not be too strong, not more than 20%. When operating and cleaning, the staff must first understand the acid concentration and the tonnage and area of the steel pipe. Similarly, while understanding these, it is also necessary for the staff to master the cleaning time. Because when cleaning, the cleaning time is determined according to the weight of the steel pipe. Can not wash for a long time, to grasp the washing time.
Furthermore, during cleaning, vibration is inevitable. Especially when the lower pipe enters the acid tank, the steel pipe is inevitably inclined. At this time, special attention should be paid to avoid splashing hydrochloric acid and accidentally hurt the people next to it. During the
pipe pickling process, unrelated personnel are not allowed to approach the pickling project to avoid accidents. After the wastewater is treated, it cannot be discharged into the soil, which will pollute the soil quality.
