P-Type Radiant Tube for Industrial Furnaces
Custom P-Shaped Radiant Tube | Heat-Resistant Alloy Furnace Tube Manufacturer | FH® Alloy
FH® Alloy manufactures P-type radiant tubes for industrial furnaces and heat treatment equipment, providing customized solutions according to furnace layout, heating system design, operating temperature, atmosphere, and customer drawings.
The P-shaped configuration combines long straight radiant sections with a return section, allowing the heating path to be arranged within a compact furnace space. This structure is suitable for industrial heating systems requiring indirect heating, controlled furnace atmosphere, and customized heat distribution.
FH® Alloy supports complete customization of the tube body, return section, mounting plate, connection structure, and material grade.
Product Overview
The P-type radiant tube features a distinctive return-flow geometry consisting of long straight tube sections connected through a curved section.
Compared with conventional straight radiant tubes, the P-type structure provides a longer heating path while maintaining a relatively compact installation arrangement.
Typical advantages include:
It is suitable for both new furnace projects and replacement of existing radiant tubes.

P-Type Radiant Tube Dimensions
The dimensions of each P-shaped radiant tube are determined by the furnace layout and heating system.
Typical dimensional parameters include:
Drawing Reference
OD = Outside Diameter
WT = Wall Thickness
L = Overall Length
C = Center Distance
R = Bend Radius
All dimensions can be manufactured according to customer drawings.
For replacement projects, customers can also provide an existing tube sample or dimensional sketch.
Material Options
Radiant tube material should be selected according to the actual furnace operating environment.
FH® Alloy can manufacture P-type radiant tubes from different heat-resistant materials, including:
The correct material selection depends on:
For projects without a specified material, FH® Alloy can provide material selection support based on actual working conditions.
P-Type Return Structure
The structural feature that distinguishes this product from standard radiant tubes is its P-shaped return path.
The long straight tube sections provide the primary radiant heating surface, while the curved return section connects the heating path into a compact assembly.
This design can provide:
The exact structure should be designed according to the furnace and heating system rather than using one standard size for every application.
Indirect Furnace Heating
P-type radiant tubes are designed for applications where the heating source should remain separated from the furnace working chamber.
Heat is transferred through the radiant tube wall and then radiated toward the furnace load.
This type of heating system can help provide:
Typical Applications
P-type radiant tubes can be used in:
They are particularly suitable for furnace designs requiring a long radiant heating path with a compact return arrangement.
Manufacturing & Fabrication
P-type radiant tubes contain multiple straight and curved sections, so dimensional control and weld quality are important during production.
Depending on the design, the manufacturing process may include:
Material Preparation → Tube Fabrication → Elbow / Return Section Preparation → Assembly → Welding → Mounting Plate Fabrication → Machining → Dimensional Inspection → Surface Cleaning → Final Inspection
Important manufacturing controls include:

FAQ
Q1: Can you manufacture P-type radiant tubes according to our drawing?
Yes. FH® Alloy supports custom production according to customer drawings, samples, and furnace dimensions.
Q2: What is the difference between a P-type and a straight radiant tube?
A P-type radiant tube incorporates a return path and multiple connected tube sections, while a conventional straight radiant tube generally uses a simpler linear structure. The P-type configuration is useful when a longer heating path needs to be arranged within a limited furnace space.
Q3: Can the tube diameter and center distance be customized?
Yes. Tube diameter, wall thickness, center distance, overall dimensions, bend radius, and mounting structure can all be customized.
Q4: What materials are available?
Typical options include 1.4848, 1.4849, 1.4852, 2.4879, high-Ni heat-resistant alloys, and other customer-specified high-temperature materials.
Q5: Can you manufacture replacement P-type radiant tubes?
Yes. We can manufacture replacements based on existing drawings, samples, photographs, and dimensional measurements.
Q6: Can the mounting plate and connection structure be supplied together?
Yes. FH® Alloy can manufacture the radiant tube together with mounting plates, flanges, connection sections, and related supporting components.
