1. Whether the seamless steel pipe with large diameter need to be finished or not?

The seamless steel pipe generally  all need to be finished whatever the caliber. And this is also an important process. So, on this issue, the answer is yes without doubt. The finishing is divided into general finishing and re-finishing. It is different in the steel finishing equipment. So we should pay attention to it.


2. What is the main steel finishing equipment and concrete content in the specific operation of cold rolling?

In the specific operation of cold rolling, it includes checking, cutting, straightening, printing, classifying packing and so on. It will use different equipment along with the different specific operation. For example, it will use the cutting machine and plate shearing machine when cutting. And it will use the straightening machine or leveler when  straightening or leveling. Therefore, the specific operation is different, and the corresponding steel pipe finishing equipment will be different, too. 


3.How to summarize the finishing of the steel pipe finishing equipment? And what is hot finishing?

Summarizing the finishing of the steel pipe finishing equipment, it is a accurate coning operation to attaining the expected goal and effect. And hot finishing means heating the parts to a definite temperature, then doing coning operation to achieve the form tolerance, which is required on the drawings.
