Title:
JOINT STRUCTURE OF FLUID TRANSPORT PIPE
Document Type and Number:
Japanese Patent JP2011127638
Kind Code:
A
Abstract:
To provide a joint structure of a fluid transport pipe, maintaining the sealability for a very low temperature fluid.
A joint 30 connecting transport pipes 20, 10 to each other, which transport liquefied gas fuel (fluid), includes: flanges 21, 11 respectively coupled to the ends of the transport pipes 20, 10; and bolts 31 fastening the flanges 21, 11 to each other. The bolt 31 is formed of material with a larger coefficient of linear expansion than the flanges 21, 11, and as the temperature of the joint 30 drops, the fastening force of the bolt 31 is increased.
