Abstract RU 2244353 C1

FIELD: packing engineering.

SUBSTANCE: proposed packing assembly has packing means installed in jointing pipe body between two supporting rings. Packing means is made in the form of set of W-shaped stacks with arc-shaped valleys and spacing members disposed between stacks. Each spacing member is made in the form of flexible ring that has three arc-shaped kinks in sectional area of which top one is disposed in a spaced relation above top of W-shaped stack and two bottom kinks are located in arc-shaped valleys of W-shaped stack so that they contact its vanes at points disposed not higher than top of W-shaped stack.
