Description
Technical field
The utility model relates to a kind of fluid-transporting tubing components, especially a kind of LNG conveyance conduit.
Background technique
When using pipeline LNG, external environment has very big influence to fluid temperature in pipeline.External environment master
Heat transfer is carried out to liquid in pipeline by direct heat transfer, heat radiation etc..Vacuum pipe generally uses segmented to make
The scene transported to is assembled again, generallys use welded connecting or flanged joint.It is the inner tube welding that will be docked using being welded to connect
Afterwards, then at docking it winds heat-preservation cotton to be kept the temperature, which process is more, takes a long time, and heat insulation effect is poor；Flanged joint meeting
Cooling capacity is caused to be easy to be lost from junction, the cold insulation that will lead in junction is ineffective, and heat insulation effect is poor.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of LNG conveyance conduit to solve prior art presence
The problem of.
The utility model uses following technical scheme:
A kind of LNG conveyance conduit, including inner and outer tubes, between said inner tube and outer tube be vacuum chamber, the outer tube and
Inner tube length is identical, and said inner tube one end has an inner tube male connector, and the other end of said inner tube has an inner tube female, described interior
Pipe male connector is adapted with said inner tube female, and described outer tube one end has an outer tube male connector, and the other end of the outer tube has one
Outer tube female, the outer tube male connector are adapted with the outer tube female, are provided with the first external screw thread, institute on the outside of said inner tube male connector
It states and is provided with the first internal screw thread on the inside of inner tube female, be provided with the second external screw thread, the outer tube female on the outside of the outer tube male connector
Inside is provided with the second internal screw thread, first external screw thread and the first internal screw thread adaptation, spiral shell in second external screw thread and second
Line is adapted.
Further, said inner tube outer surface is provided with multiple annular brace pieces to support the outer tube.
Further, the annular brace piece is in netted, and the annular brace piece is made of polyurethane material.
Further, first external screw thread, the first internal screw thread, the second external screw thread and the second internal screw thread are that thread form angle is
55 ° of pipe screw thread.
Compared with the prior art, the advantages of the utility model are:
1. the connection type of the inner and outer tubes of a LNG conveyance conduit more than is to be threadedly coupled, and work efficiency is high, and connection is completed
The cavity between inner and outer tubes is vacuumized afterwards, makes whole LNG feed-line all under vacuum heat-preserving, heat insulation effect
It is good.
2. the support chip made of polyurethane material, thermal coefficient is low, can greatly reduce the cold draining amount of the outer tube of inner tube.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
