Serrated Fin Tube for HRSG Harps, Superheater, Economizer, Evaporator

Serrated fin tubes are critical high-efficiency components in Heat Recovery Steam Generators (HRSGs), maximizing heat transfer surface area for economizers, evaporators, and superheaters within power plants. These tubes, often high-frequency welded with serrations (segmented fins), reduce total equipment size, enhance gas-side heat transfer, and manage high-temperature flue gases efficiently.

Yuhong Group specializes in the manufacture of serrated finned tubes and have long supplied markets in the Middle East, South America, Africa, Europe, and other regions, additionally, we can provide assembly services for the Harps, as well as on-site installation guidance.

Key Applications in HRSG Harps

Economizers (Preheaters): Located in the colder, downstream section, these tubes preheat feedwater using low-grade heat. Serrated fins are often used here to optimize heat absorption from the flue gas.
Evaporators: These tubes convert preheated water into saturated steam. They are frequently used in the "water wall" or floor of the HRSG, where high thermal conductivity is required.
Superheaters: Positioned in the hottest gas stream, these tubes raise the temperature of saturated steam above the saturation point, often requiring durable material to handle high-temperature gas, where serrated fins help distribute heat efficiently.

Specifications and Advantages

Material: Frequently manufactured from carbon steel, alloy steel, or stainless steel to withstand harsh, high-temperature, high-pressure environments.
Design: The serrated design (also called segmented) breaks up the boundary layer of the flue gas, enhancing heat transfer coefficients compared to solid fins.
Fabrication: High-frequency electric resistance welding is used to bond the fin to the base tube, ensuring a secure metallurgical bond and reliable thermal performance.
HRSG Harps: These tubes are typically arranged in vertical or horizontal modules (harps) and connected via headers with crossover piping.

To get an accurate quotation for serrated fin tubes, you must provide the base tube specifications (OD, wall thickness, material, and total length), fin specifications (height, thickness, density, and material), and total quantity. Essential technical details include the serration pattern, requiredPlain End lengths, and relevant design standards.

Required Information for Quotation

Base Tube Specifications: Outside Diameter (OD) and Wall Thickness (WT) (e.g., 25.4 mm OD x 2.77 mm WT or 1'' OD x 12 BWG).
Tube Material: Grade (e.g., SA106 Gr.B, Stainless Steel TP304H, Alloy steel T11/T22).
Tube Length: Total length, and specific length of plain (unfinned) ends.
Fin Dimensions: Fin height (e.g., 15.88 mm), thickness (e.g., 1.0 mm), and type.
Fin Density: Fins per inch (FPI) or pitch (e.g., 6 mm).
Serration Pattern: Number of segments or width of serration.
Fin Material: Carbon steel, stainless steel, or alloy steel.
Quantity: Total number of tubes or total length in meters/feet.
Applicable Standards: E.g., ASME, EN, or GB standards.
