Large
It is used as a water wall tube loaded with a highly heated flux and is also expected to find broadened other uses in the viewpoint of its energy saving effect and higher safety against the overheating damage.
This has a groove on its inside surface which functions to raise thermal efficiency by distrubing the fluid within the tube,featuring an extremely high thermal conduction property.
