Method for connecting radially placed connecting pipe and shell on pressure vessel

The invention discloses a method for connecting a radial mounting type connecting pipe and a shell on a pressure vessel, and belongs to the technical field of pressure vessel manufacturing and welding, and the method comprises the following steps: S1, according to the direction of the connecting pipe, carrying out lofting and scribing on the vessel shell; s2, pipe orifice tapping and beveling machine machining are carried out on the container shell, and a groove is machined after a curved surface base material of the pipe orifice part of the container shell is milled into a plane; s3, the connecting pipe is subjected to beveling machine machining, and a groove is machined in the end, close to the container shell, of the connecting pipe; s4, lofting and marking on the connecting pipe; s5, the connecting pipe is placed and assembled on the container shell in the radial direction; and S6, the connecting pipe and the connecting joint of the container shell are welded.
