Beschreibung
Zusammenfassung:	civil engineering. SUBSTANCE: method is used in construction of pipelines with internal protective lining. Metal pipes with internal coating are set on sealing cylindrical bushing which has projections on external surface and groove in the middle potted with sealing compound. Squeezing cylindrical coupling with at least one circular groove of cylindrical form on external surface and with entry radius on groove side is positioned on pipe butt-joint from external side. Side sections of coupling are arranged from different sides of butt-joint with entry radius towards reducing member. Coupling reduction is performed from one end of coupling to the other till external surface of coupling takes cylindrical form. Squeezing cylindrical coupling may have thread and/or grooves on internal surface. EFFECT: higher reliability. 2 cl, 2 dwg
