After the steel pipe is produced, in order to ensure that two connected steel pipes are reliably welded and connected, the flatness or perpendicularity of the pipe orifice of the steel pipe (the perpendicularity between the end face of the pipe orifice of the steel pipe and the center line of the steel pipe) needs to meet the form and position tolerance requirement, so that the steel pipe needs to be detected.
At present, the detection of the flatness or verticality of the pipe orifice of the steel pipe is finished by using a right-angle detection ruler, wherein two right-angle sides of the right-angle detection ruler are not equal in length, and the longer right-angle side is larger than the diameter of the steel pipe. When in detection, the shorter right-angle side is abutted against the outer circumferential surface of the steel pipe, the longer right-angle side vertically passes through the center of the steel pipe and is abutted against the end face of the pipe orifice of the steel pipe, then, whether a gap exists between the upper end and the lower end of the end face of the pipe orifice of the steel pipe and the right-angle side is visually detected, if no gap exists, the flatness or the perpendicularity of the pipe orifice meets the requirements, if the gap exists, a clearance gauge is used for detecting the size of the gap, and then, whether the flatness or the perpendicularity of the pipe orifice meets the requirements is judged.
However, in actual operation, when the right-angle detection ruler is used for detecting the flatness or perpendicularity of the pipe orifice of the steel pipe, the position of the right-angle detection ruler is difficult to fix, so that the operation error of the subsequent feeler ruler is large, and the detection precision is low.
