Seamless steel pipes are very common in daily life. Everyone hopes to increase his utilization rate to the maximum value in order to better use seamless steel pipes. How can the life of seamless honed steel tubes be increased?
1. Seamless steel pipe must be worn with labor protection products before pickling. For the working environment on site, detailed inspection is also carried out, mainly to check whether the sling of the steel pipe is in good condition, and the work can be carried out after the confirmation is completed. ,
2. When the seamless steel pipe is pickled, the pickling is mainly acid washing with hydrochloric acid, and the content of hydrochloric acid is generally 18% to 20%.
3. The staff also needs to know the acid concentration and temperature and the tonnage of the acid pickling pipe before the operation.
4. For pickled steel pipes, it is best to control the weight between 2 and 5 tons each time, and the time is 5 to 15 minutes. Time needs to be adjusted according to the weight. Steel pipes need to be vibrated frequently during the pickling process. When the pipe is placed under the acid tank, the steel pipe should be tilted to prevent accidental injury to hydrochloric acid. Seamless steel pipe is made of high-quality carbon steel such as 10#, 20#, 30#, 35#, 45# or low-alloy structural steel such as 16Mn and 5MnV or hot-rolled or cold-rolled alloy structural steel such as 40Cr, 30CrMnSi, 45Mn2 and 40MnB. Made of. Seamless pipes made of low carbon steel such as 10# and 20# are mainly used for fluid conveying pipes. Seamless tubes made of medium carbon steel such as 45# and 40Cr are usually used to make mechanical parts, such as parts for automobiles and tractors.
