SEGMENTED FLANGE COUPLER FOR GROOVED PIPE

摘要

A segmented flange coupler is disclosed for connecting the free end of a grooved pipe to a fitting having a flange connector. The segmented flange coupler is formed of end-to-end connected individual coupling segments (50, 52) which are configured to move both circumferentially and radially into concentricity during the tightening of their connecting bolts. This is achieved by providing complementary surfaces of revolution (54, 56) about their overlapped bolt receiving apertures (30, 32). These surfaces of revolution are preferably in the form of mating convex and concave conical surfaces.
