Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipes, in particular to a drilling device for processing seamless steel pipes. Background Art

[0002] Seamless steel pipe is a long steel strip with a hollow cross-section and no seams around it. Generally, seamless pipes are made of high-quality carbon steels such as 10, 20, 30, 35, 45, low-alloy structural steels such as 16Mn, 5MnV, or alloy steels such as 40Cr, 30CrMnSi, 45Mn2, 40MnB, etc., which are hot-rolled or cold-rolled. Seamless pipes made of low-carbon steels such as 10 and 20 are mainly used for fluid delivery pipelines. Seamless pipes made of medium-carbon steels such as 45 and 40Cr are used to manufacture mechanical parts, such as load-bearing parts of automobiles and tractors. Some seamless steel pipes need to be punched for external connection and fixation.
