Rifled Tube (Ribbed Tube)
Feature 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.
Low-carbon steel, Low-alloy steel
The details of the size will be determined by meeting.
Boiler tubes for power generation and energy industry
(Subcritical pressure boiler , Supercritical pressure boiler, etc)
