Next-Generation Cracking Tube with Aluminum Oxide Layer on the Inside Surface
Kubota developed a surface modification technology for forming an aluminum oxide layer on the surfaces of metallic materials. The inert aluminum oxide layer is very dense, adherent, robust and highly stable even under high temperatures, which can dramatically improve the material’s resistance to carburization, oxidation and coking.
AFTALLOY is a next-generation material developed for the purpose of applying this surface modification technology to cracking tubes for petrochemical plants. This can extend tube life and increase the operation efficiency of thermal cracking furnace.
Concept:

◆ Superior resistance to carburization and oxidation
The dense aluminum oxide surface with high chemical stability and peeling resistance dramatically extends the life of cracking tubes.
◆ Superior anti-coking performance
Since the dense, robust aluminum oxide surface reduces catalytic coking, your cracking furnace can operate longer run times between decoking, which dramatically increases furnace operation efficiency.
Combination with the Flow Mixing Feature:

Applying another Kubota proprietary technology, MERT, to AFTALLOY tubes dramatically improves cracking tube performance and provides additional user benefits.
