摘要

PROBLEM TO BE SOLVED: To improve a sealing performance when an excessive external force is loaded to a loose flange type flared pipe coupling, repeatedly in particular.;SOLUTION: A loose flange type flared pipe coupling forces a loose flange 4 to be engaged with a flare part 2 formed by flange machining an end of a steel pipe 1, end surfaces of the flare part 2 to abut on each other by interposing a gasket 3 and an abutment part to be sandwiched between the loose flanges 4 to be mechanically fastened, wherein the flare part end surface angle [] between an end surface of the flare part 2 and the center shaft of the steel pipe, and the corner curvature radius R [mm] between the flare part 2 and steel pipe 1, satisfy 870.88ln(R)+89.3. The excellent sealing performance is thus provided.;COPYRIGHT: (C)2010,JPO&INPIT
