Title:
HIGH THERMAL EFFICIENCY TUBE FOR CONVEYING FLUIDS
Document Type and Number:
WIPO Patent Application WO/2016/115612
Kind Code:
A3
Abstract:
The present invention relates to a tube for injecting thermally insulated fluids, in that a technology capable of increasing thermal efficiency using high-efficiency shaped thermal insulators is developed, providing an insulating layer of uniform density and thickness in the annular space between concentric tubes. The risk of welding failures when joining concentric tubes is also reduced in that a specific geometry is used in the welding seams, promoting a satisfactory distribution of mechanical stresses resulting from expansion differences between the inner tube and the outer tube.
