FIELD: oil- field equipment. SUBSTANCE: invention relates to packing devices of pipelines and can be used in pipelines operating at high pressure in oil and gas industries, particularly, in reservoir pressure maintenance systems. Proposed packing of pipeline joints consists of flanges with seat for centering ring, guard bushing, fasteners and Δ-section sealing member. Surface forming flow section of sealing member is made convex, pointing to center. Sealing member is provided with bead on periphery. Bead is essentially one-side wedge with thickened part towards periphery. Lock recess for bead is made in one of flanges. Flange at delivery side is provided with guard bushing overlapping by open end the edge of lobe of sealing member. EFFECT: improved reliability in operation, simplified design of packing. 2 dwg
