FH® Alloy manufactures custom U-shaped radiant tube assemblies for industrial furnaces and heat treatment equipment. The assembly can be supplied with the U-shaped tube, insulation blocks, mounting plate, and other installation components according to the customer's furnace design.
The U-shaped configuration provides a long radiant heating path within a relatively compact installation space and is commonly used in furnace systems requiring indirect heating, controlled atmosphere, and stable heat transfer.
All dimensions, materials, connection structures, and mounting arrangements can be customized according to drawings or existing furnace requirements.
Product Overview
This U-shaped radiant tube consists of two parallel straight tube sections connected by a return bend at the top.
The lower section is integrated with insulation blocks and a mounting base, helping the radiant tube fit securely into the furnace structure while reducing heat loss around the installation area.
Typical customization includes:
FH® Alloy supports OEM and drawing-based manufacturing for new furnace projects and replacement applications.

Material Options
The material of a radiant tube should be selected according to the actual operating conditions rather than temperature alone.
FH® Alloy can provide different heat-resistant materials depending on:
Typical material options can include:
If the material has not yet been determined, customers can provide the operating conditions for material selection support.
Integrated Insulation Block & Mounting Structure
A key feature of this radiant tube assembly is the customized lower mounting system.
The tube can be supplied together with:
The insulation blocks help reduce heat transfer around the furnace opening and support the tube installation according to the furnace structure.
The exact insulation material and mounting design can be customized according to the project requirements.
Indirect Heating Performance
U-shaped radiant tubes are commonly used where the heat source needs to remain separated from the furnace chamber.
Heat generated inside the radiant tube is transferred through the tube wall and radiated toward the furnace load.
This arrangement can provide:
Typical Applications
U-shaped radiant tube assemblies are suitable for:
They are particularly suitable for furnace systems requiring custom radiant heating elements with integrated mounting structures.
Manufacturing Process
Depending on the design, the production process may include:
Material Preparation → Tube Forming → Bend Preparation → Assembly → Welding → Machining → Mounting Plate Fabrication → Insulation Assembly → Dimensional Inspection → Final Inspection
