FIELD: pipeline transport. SUBSTANCE: method relates to protection of pipeline connections against corrosion. Sealing between external surface of bushing and coated internal surfaces of pipe ends is performed before or after pipe connection by welding. To this end, ends of pipes located opposite to bushing or sealing elements of bushing are squeezed. Pipe ends are calibrated by internal diameter for length not exceeding length of bushing by value of clearance necessary for pipe connection by welding. Prior to installation of sealing elements, external surface of bushing ends is coated with adhesive compound based on organic and inorganic compounds or on their compositions. EFFECT: simplified technology, reduced expenses. 3 cl, 1 dwg
