Document Type and Number:
WIPO Patent Application WO/2015/019622
Kind Code:
A1
Abstract:
Provided is a seal ring structure for a high-pressure pipe joint that is capable of improving the sealing performance and vibration resistance of a pipe joint. The seal ring structure comprises a seal ring and a retainer. The seal ring is donut shaped. A cross-section of the seal ring comprises a quadrangle having two diagonal lines that are orthogonal to each other. One diagonal line is parallel to a planar perpendicular line formed by the donut shape, and opposing vertexes on the diagonal lines are in contact with the end face of each joint. The retainer is able to engage with the peripheral edge of the joint end face.
