The production laboratory of the acid pickling and passivation 20 # seamless steel pipe company has complete analysis and testing methods; The cleaning engineering personnel have strong technical abilities, including 24 engineers; The equipment and supporting facilities for cleaning, phosphating, passivation pre coating, surface treatment, coating, chemical plating, packaging, pressure testing, etc. are complete, and the construction ability is strong. It is in a leading position in the same industry in China. After technological transformation and expansion, it currently has an annual construction capacity of 1 million square meters for cleaning, pre coating, and coating.
The specific process of pickling and passivating seamless steel pipes (process flow): steel pipe → pickling → phosphorus saponification (i.e. lubrication) → cold drawing. If there is also secondary cold drawing, whether annealing is needed depends on the type of steel. Generally, low-carbon steel does not require annealing. After one cold drawing, it undergoes lubrication, cold drawing, annealing, straightening, cutting, finished product inspection, and packaging for storage. High quality requirements for acid pickling and passivation treatment.
