Large-caliber steel pipes have their own unique characteristics.It can be used in many fields.In the production of large-caliber steel pipes, the latest production technology is used to make large-caliber steel pipes work normally.
What is the manufacturing process of large-caliber steel pipe?Next, we will introduce a production technology of large-caliber steel pipes.
Steel pipe drawing is the most commonly used and mature production process in the production of large-caliber steel pipes.The so-called pipe drawing refers to the tension of the pipe billet in the machine chain.Through the combination of the output abrasive tool and the internal control mandrel, the large-diameter steel pipe blank is drawn into the specifications specified in the design.The general principle is: from small to large, from thick to thin, if from small to large refers to reaming, this is often used in the production process of large-diameter and large-diameter steel pipes.The biggest feature of large-diameter steel pipe drawing is that the metal phase transition capacity is limited, so the diversion capacity is limited every time it is drawn. Therefore, if you want to extend more, you must go through high temperature combustion, so that the internal metal molecular phase of the large-diameter steel pipe can be restored to its original state without modification. If the specification range of the forced drawing channel is too large, it will directly lead to the fracture or deformation of the large-diameter steel pipe.This special performance of the drawn pipe makes the production process of large-diameter steel pipe repeated in the drawing, annealing and then drawing process, and finally meets the required specifications.
Through the above content, we have learned about the most mature technology of large-diameter steel pipes, so as to better understand large-diameter steel pipes.In practical applications, large-caliber steel pipes need to be selected correctly in order to use large-caliber steel pipes rationally.
