A unit for pipe connection, preferably of metal ones, by means of sequential lining-up of pipes in vertical space with following welding, includes reducing fitting, this includes flange installed on the pipe with smaller diameter and prepared in respective way for connection to each other ends of pipes of both diameters, with further reducing fitting for pipes with same diameters with prepared in proper way for connection of pipe ends. A reducing fitting from pipes with smaller diameter to larger diameter includes cross end stiffener as flange arranged in circle of the lower section of pipe with smaller diameter and equipped with component long stiffeners installed and fixed in long cuts provided in the upper end of the pipe with larger diameter according to dimensions of the lower part of stiffeners. Further reducing fitting for pipes with same diameters is arranged with preliminary connection of the ends of those, each of that is equipped with connection semi-band, by means of adjusting studs installed to openings of ledges fixed on the bodies of pipes being connected. |
