The material of the pipe with no drift is No. 15 mesh, the accuracy is mass pass level, and the pressure source is selected according to the technical documentation recommended by JB/Z95-7 pressure system for integrated steel pipe insertion. The size of the threaded hole is in accordance with GB196-63, and the manufacturing precision is in accordance with GB197-63, grade 26. The vertical difference between the end face of the screw hole and the center of the thread is o. When using a single piece or a small batch of main production pipe joints, in order to meet the production conditions, the short structure is modified, see J8/29-6.
