Abstract

PIPE JOINT Provided herein is a pipe joint of a relatively small joint diameter for use under ultrahigh pressure conditions. The pipe joint includes first and second joint members having mutually communicating fluid passages; and a gasket interposed between abutting end surfaces of the first and second joint members. The first and second joint members have ring-shaped seal projections formed at the abutting end surfaces thereof. The pipe joint satisfies a coefficient F of 0.4 or less in the following formula (1). Formula (1): F = (D32 - D12)/ (D42 - D22), where D1 represents the inner diameter of the first and second joint members, D2 represents the inner diameter of the gasket, D3 represents the diameter of the seal projections, and D4 represents the outer diameter of the gasket.
