Alloy Engineering radiant tubes out perform and last longer than the tubes they replace to reduce maintenance, production, and energy costs. They are thin, light weight and resist sagging and cracking. Made from ductile high-nickel, low-carbon alloys with a controlled, tight grain structure, our radiant tubes have high resistance to thermal fatigue.
We understand how and why radiant tubes fail and may use various grades of wrought materials in a fabrication to enhance the performance of specific areas of a tube. Our fabricated tubes have a low mass that enhances heat transfer for high efficiency while reducing energy and operating expense.
We fabricate tubes in any configuration and wall thickness and support all furnace OEM tube designs. We can repair or replace return bends, flanges, bungs, and straight components.
According to application requirements, tubes in all sizes and configurations are made from a variety of materials including stainless steel, Inconel 600 and 601, Incoloy 800, RA330 or RA333. For carburizing, carbonitriding, hardening or annealing, material selection is made to avoid problems such as creep deformation and metallurgical deterioration.
Wall thicknesses range from 1/8 to ¼ in. Pressed return bends are a feature on most Alloy Engineering tube assemblies to assure uniform metal section for consistent heat transfer.
