Custom Flange-Mounted Radiant Tubes | OEM Manufacturing | FH® Alloy
FH® Alloy manufactures I-shaped radiant tubes for industrial furnaces and heat treatment equipment, providing customized solutions for indirect heating systems used in various thermal processing applications.
Compared with bent or U-shaped designs, the I-shaped radiant tube features a straight-through structure that is suitable for furnace systems requiring simple installation, convenient maintenance, and efficient radiant heat transfer.
The product can be customized according to customer drawings, furnace dimensions, operating conditions, flange requirements, and material specifications.
Product Overview
The I-shaped radiant tube is a straight radiant heating tube commonly used in industrial furnace systems where indirect heating is required.
Its straight cylindrical structure, together with customized flange connections, makes it suitable for furnace layouts that require:
FH® Alloy can manufacture I-shaped radiant tubes with different diameters, lengths, wall thicknesses, flange dimensions, and alloy materials according to actual service requirements.

Typical material options include:
If the material has not yet been determined, we can recommend a suitable grade based on the actual working conditions.
Designed for Indirect Heating
I-shaped radiant tubes are widely used in furnace systems where the heat source must be separated from the furnace chamber.
During operation, heat is generated inside the tube or along the tube system and transferred through the tube wall into the furnace chamber by radiation.
This design helps provide:
Typical Applications
I-shaped radiant tubes are suitable for:
They are especially suitable for furnace systems requiring straight radiant tube structures with flange-mounted installation.
