Product Description

Product Description

X11CrMo5 1.7362 Seamless Multi Rifled Boiler Steel Tubes

Application
The rifled tubes are served in super/ultra super critical water wall panels over 300,000KW of boiler, chemical, electricity industries. 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.
