Radiant Tubes, Tube Supports & Generator Retort Tubes

Engineered for Demanding High-Temperature Furnace Applications

‍

At Allegheny Alloy, we design and manufacture standard and custom radiant tubes, tube supports, and generator retort tubes for demanding heat-treating and industrial furnace applications. Built from heat-resistant alloys, our products are engineered to withstand extreme temperatures, repeated thermal cycling, and demanding furnace atmospheres where durability, dimensional stability, and long service life matter.

From heat treating and annealing to carburizing, controlled-atmosphere processing, and other high-temperature applications, Allegheny Alloy can manufacture radiant tubes, tube supports, and generator retort tubes to meet your specific operating requirements. Whether you need a standard replacement component or a completely custom solution, our team can help develop the right product for your furnace and process.

Every radiant tube, support, and retort is engineered around the requirements of the application. We consider factors such as operating temperature, furnace atmosphere, tube dimensions, heat transfer requirements, load conditions, thermal cycling, material compatibility, and expected service life when developing a solution. By selecting the appropriate heat-resistant alloy and construction method, we help customers achieve reliable furnace performance while reducing distortion, cracking, premature failure, and frequent replacement.
