FIELD: engineering; high pressure flexible piping.
SUBSTANCE: flexible gas piping contains two spherical counter flanges divided by a circular clearance with a circular elastomer positioned between them. The circular clearance uniformly tapers from its centre to periphery, furthermore, the area taken by the circular elastomer near the centre is larger than the area taken by the said elastomer near the periphery.
EFFECT: increased durability.
