Product Specification

HT W-Type Radiant Tube – 1860 × 610 mm
Custom Multi-Pass Radiant Tube for Industrial Furnaces | FH® Alloy
FH® Alloy manufactures HT W-type radiant tubes for industrial furnaces, heat treatment equipment, and indirect heating systems.

This customized W-shaped radiant tube is manufactured from HT heat-resistant alloy, with an overall size of 1860 × 610 mm. Its multi-pass W-shaped configuration provides an extended radiant heating path within a compact installation area, making it suitable for furnace systems requiring efficient heat distribution and customized structural integration.

The complete radiant tube assembly can be manufactured with mounting plates, insulation blocks, connection tubes, and other installation components according to customer drawings.

Product Specifications

W-Type Radiant Tube Dimensions
The overall dimensions of this radiant tube are:
1860 × 610 mm
Because the exact tube diameter and wall thickness are not specified for this project, these parameters should be manufactured according to the approved technical drawing.

Typical customizable dimensions include:

• L – Overall Length
• W – Overall Width
• OD – Tube Outside Diameter
• WT – Wall Thickness
• C – Center Distance
• R – Return Bend Radius
• Mounting plate dimensions
• Mounting hole positions
• Connection tube diameter
• Connection tube length
• Insulation block dimensions

All dimensions can be customized according to the customer's furnace design.

HT Heat-Resistant Alloy
This W-type radiant tube is manufactured from HT heat-resistant alloy, a material grade used for components operating under demanding elevated-temperature conditions.

For industrial furnace applications, HT alloy can provide characteristics such as:

• Good high-temperature strength
• Good oxidation resistance
• Stable structural performance at elevated temperatures
• Suitability for repeated heating and cooling cycles
• Good performance for fabricated and cast furnace components

Actual radiant tube service life depends on multiple operating factors, including:

• Furnace temperature
• Furnace atmosphere
• Burner conditions
• Thermal cycling frequency
• Tube wall thickness
• Weld design
• Operating and maintenance conditions

The exact HT material specification can also be produced according to the customer's required standard.

W-Shaped Multi-Pass Structure
The main feature of this product is its W-shaped multi-pass heating path.
Multiple straight tube sections are connected through return bends, creating a long continuous flow path inside a relatively compact furnace area.

Compared with a conventional straight radiant tube, this design provides:

• Longer radiant heating path
• Larger effective heat-transfer surface
• Compact installation arrangement
• Flexible furnace layout
• More extensive heat coverage
• Custom burner and exhaust arrangement

The W-type geometry is especially useful when the furnace requires a large radiant area without excessively increasing installation length.

Designed for Indirect Furnace Heating
W-type radiant tubes are commonly used in industrial furnace systems where the combustion process 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 help provide:

• Controlled furnace atmosphere
• Reduced direct flame contact with workpieces
• Stable radiant heat transfer
• More uniform furnace temperature
• Reliable continuous heating

Integrated Insulation & Mounting Structure
As shown in this product configuration, the radiant tube can be supplied as a complete assembly with:

• Furnace mounting plate
• High-temperature insulation blocks
• Mounting bolts or studs
• Burner-side connection
• Exhaust-side connection
• Supporting structures

This integrated design is especially useful for furnace builders and replacement projects because the installation interface can be manufactured according to the existing equipment.

Customizable items include:

• Mounting plate size
• Plate thickness
• Bolt-hole layout
• Insulation thickness
• Tube opening positions
• Connection positions
• Overall installation orientation

Typical Applications
HT W-type radiant tubes are suitable for:

• Heat treatment furnaces
• Annealing furnaces
• Hardening furnaces
• Tempering furnaces
• Carburizing furnaces
• Continuous furnaces
• Roller hearth furnaces
• Protective atmosphere furnaces
• Steel processing lines
• Industrial heating equipment

They are particularly suitable for applications requiring a long multi-pass radiant heating path within limited installation space.

Manufacturing Process
Depending on the drawing and tube design, production may include:
Material Preparation → Tube Production → Straight Section Preparation → Return Bend / Elbow Fabrication → Assembly → Welding → Mounting Plate Fabrication → Insulation Assembly → Dimensional Inspection → Final Inspection
For W-type radiant tubes, manufacturing control is especially important because multiple tube sections and return bends must remain correctly aligned.

Key control points include:

• Tube straightness
• Wall thickness consistency
• Center distance
• Return bend geometry
• Weld quality
• Parallelism between tube sections
• Overall dimensions
• Mounting plate accuracy
• Connection alignment
