The HK40NB centrifugal casting tubes, OD 88.9 mm, are made by centrifugal casting method, with heat resistant
nickel alloys HK40Nb.
After centrifugal casting process, the boring machining will be done for the inside holes, and other machining jobs
will be done.
The heat exchange tubes are for the Air Preheater of carbon black reactor for air preheating application.
DTL produced thousands of such heating tubes for carbon black plants, with reliable quality.
For HK40NB, we guarantee the correct chemical composition for chrome, nickel, niobium,etc., and we guarantee the
sound mechanical properties like Tensile Strength, Yield Strength, Elongation at Break, etc.,
All the requested NDT will be done.
We can also supply seamless tubes 253MA or S30815 for the carbon black plants.
