Document Type and Number:
WIPO Patent Application WO/2016/051770
Kind Code:
A1
Abstract:
A guide mechanism for guiding a male-side joint part into a female-side joint part when connecting the male-side joint part and the female-side joint part of a bayonet joint in a vacuum-insulated double-walled pipe for transporting low-temperature fluids and having an inner pipe and an outer pipe fitted thereon with a vacuum layer interposed therebetween, wherein: one joint flange of the male-side joint part and the female-side joint part of the bayonet joint is provided with a guide member in which the length in the axial direction of the double-walled pipe is greater than the insertion distance for inserting the male-side joint part into the female-side joint part; the other joint flange of the male-side joint part and the female-side joint part is provided with a guidable part to be guided by the guide member when inserting the male-side joint part into the female-side joint part; and the radial clearance between the guide part and the guidable part is set so as to be no greater than the radial clearance between the male-side joint part and the female-side joint part.
