U-Shaped Radiant Tube Manufacturer | Heat-Resistant Furnace Tubes | FH® Alloy

U-Shaped Radiant Tube
Reliable Indirect Heating Solution for Industrial Furnaces

FH® Alloy manufactures U-shaped radiant tubes for industrial furnace heating systems. These tubes are widely used in heat treatment and continuous furnace applications where stable indirect heating, uniform temperature distribution, and long service life are required.

The U-shaped structure provides an efficient radiant heating surface while separating the combustion process from the furnace atmosphere. This helps improve heating consistency and protect product quality during operation.

Product Overview
Our U-shaped radiant tubes are designed for use in a wide range of thermal processing equipment. According to furnace structure and service conditions, the product can be supplied in different sizes, wall thicknesses, material grades, and fabrication designs.

FH® Alloy supports custom manufacturing based on drawings, samples, or working conditions.
