FIELD: construction, particularly oil-trunk pipeline laying.
SUBSTANCE: device comprises frame, centrators, hydraulic press with hydraulic drive, technological plates and compression unit. Centrators are made as adjustable rollers, which support pipes. Technological panels are made as panel of front pressing unit, movable panel of compression unit and rear support panel. The plates are connected with each other by means of guiding tightening bars. Compression unit is made as two roller pairs. The first roller pair defined in clutch compression direction includes rollers for one clutch section compression. The second roller pair includes rollers with inner profiles, which simulate half of outer compressed clutch surface. As said rollers touch each other the rollers define total outer surface of compressed clutch. The rollers are installed so that total clutch surface may be compressed.
EFFECT: increased connection reliability.
