A method for connecting pipes with different diameters includes implementation of pipe jointing in vertical space by means of flanges, welding those. To the lower end of the pipe with smaller diameter at given distance from the end in circle one connects support rigidity rib as a flange. One equips the lower end of the pipe with long rigidity ribs in number not less than three as parallelepiped joint plates that are attached at beneath to the flange and along, to the edge of the pipe body. One installs the last ones to long cuts that are provided in the end of the pipe with larger diameter where joints of those are fixed by welding. After fixation of joint plates to the flange and to the body of the pipe at beneath one equips those with reinforcement circular diaphragm that in circle is connected to the end of the pipe with smaller diameter, and at radii – to the lower parts of the joint plates. |
