Lord Fin Tube-Rifled tube is steel with spiral ribs on the inner surface

Rifled tube is steel with spiral ribs on the inner surface which are produced by cold drawing process.
Lead angle of the ribs (spiral angle) P is 30 degrees to the tube axis plane.
By irregularities and spiral effect of inner surface, it is possible to prevent the film boiling when the water in the boiler to boil. And it prevent overheating.
Standard material
Low-carbon steel, Low-alloy steel
Processable size
The details of the size will be determined by meeting.
Usage
Boiler tubes for power generation and energy industry
(Subcritical pressure boiler , Supercritical pressure boiler, etc)
 
Inner Finned Tube increaces the heat transfer performance by making fins inside.
Material
Carbon steel tube
Alloy steel tube
Processable size
We would have a meeting before manufacturing because there are some restrictions between each dimension.
 
Usage

Oil cooling steel tube
