Multi-rifled seamless steel tube

 Multi-rifled seamless steel tube 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 iits energy saving effect and higher safety against the overheating damage.

Multi-rifled seamless steel tube

This has groove on its inside surface which functions to raise thermal efficiency by distrubing the fluid within the tube, featuring and extremely high thermal conduction property.


Available grades and size range:

Multi-rifled seamless steel tube are produced to meet specific end use requirements, specifications, tolerances and chemistries.

Rifled tube

The rifled tube 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 overheating damage.

The rifled tube has a groove on its inside surface that functions to raise thermal efficiency by disturbing the fluid within the tube, featuring an extremely high thermal conduction property.
