BELLOWS FOR COMPENSATION OF DEFORMATION IN PIPE LINE Russian patent published in 1998 - IPC

FIELD: connection of high-pressure main pipe lines. SUBSTANCE: radius of profile of bellows corrugations is equal to R=(8-12)t, where t is thickness of wall of corrugated pipe of bellows; radius of profile of corrugation space is equal to r=(0.3-0.4)R; height of corrugations is equal to H=(2.5-3.2)R; angle of inclination of rectilinear sections of profile of reinforcing half-rings is equal to γ = 7^°...10^° and undercut of corrugations is equal to α = (0,45...0,55)γ. EFFECT: enhanced reliability and serviceability; reduction of mass and overall dimensions of bellows. 2 cl, 4 dwg
