First, the zigzag pipe of Ji'nan galvanized pipe is tortuous because of the improper adjustment of rolling mill, the residual stress during rolling and the reason of cooling unequal along the section and length of pipe. As a result, a straight tube can not be obtained directly from the mill, so that the rules of the skill condition can be satisfied only by the zigzag of the cold straightening tube.
Second, the fundamental principle of straightening is to make the precision steel pipe elastic-plastic and tortuous, and become a minor tortuosity from large tortuosity, so it is necessary for steel pipes to be subjected to repeated twists and turns in the straightening machine. The degree of repeated twists and turns of the Ji'nan galvanized pipe is mainly determined by the adjustment of the straightening machine.
Third, there are many factors that affect the quality of the straightening, such as the zigzag degree of the precise steel pipe, the scale of the steel tube and the type of material straightening, the adjustment of the parameters, etc. The use of tin cans: tin coating is non-toxic, a large number of products used in contact with food and beverage, the largest use is to make tin cans.
