At Wuxi Yansheng Technology Co., Ltd., we take pride in our role as a leading manufacturer of high-performance heat transfer components. Established in 2017, our factory spans 1,000–3,000 square meters and is staffed by 101–200 skilled professionals. With an annual export value exceeding US$50 million, we serve diverse markets across North America, South America, Europe, Asia, Africa, and Oceania. Our Carbon Steel Stainless Steel Alloy Boiler Fin Tube is engineered to maximize heat exchange efficiency, delivering reliable performance in demanding industrial applications. This product combines the strength of carbon steel, the corrosion resistance of stainless steel, and the durability of alloy materials, making it an ideal choice for boiler systems, heat exchangers, and condensers.
Our fin tubes are manufactured using advanced welding and extrusion techniques, ensuring consistent fin-to-tube bonding and optimal thermal conductivity. The design minimizes pressure drop while enhancing heat transfer surface area, resulting in superior energy savings. Whether you need custom dimensions, specific fin geometries, or special surface treatments, we offer tailored solutions to meet your project requirements.

Key Features and Benefits
Enhanced Heat Transfer Efficiency: The finned design increases the surface area by up to 10 times, significantly improving heat exchange rates and reducing energy consumption.
Durable Material Combination: Carbon steel provides strength and cost-effectiveness, stainless steel offers excellent corrosion resistance, and alloy steel ensures high-temperature performance. You can choose the ideal mix for your operating conditions.
Customizable Geometry: We offer a variety of fin types (solid, serrated, extruded) and dimensions to match your specific heat transfer requirements and space constraints.
Reliable Bonding: Our manufacturing process ensures a metallurgical bond between the fin and tube, eliminating gaps that could cause thermal resistance. This results in consistent performance over the product's lifespan.
Low Pressure Drop: Optimized fin spacing and shape minimize airflow resistance, allowing your system to operate efficiently with lower fan power requirements.
Wide Application Range: Suitable for boilers, superheaters, economizers, air preheaters, and other heat recovery equipment in power plants, petrochemical plants, and industrial processes.
Certified Quality: Our production is carried out under strict quality management systems, including ISO9001, ISO14000, and other certifications. Each fin tube undergoes rigorous inspection for dimensional accuracy, pressure testing, and material verification.

Frequently Asked Questions (FAQ)
Q1: What materials are available for your boiler fin tubes?
A: We offer carbon steel (e.g., A106 Gr.B), stainless steel (304, 316L, 310S), and alloy steel (T11, T22, T91). You can also request special alloys. The choice depends on your operating temperature, pressure, and corrosion environment.
Q2: Can you produce fin tubes with non-standard dimensions?
A: Yes, we specialize in custom manufacturing. You can specify outer diameter, wall thickness, fin height, fin pitch, and tube length. We will produce according to your drawings or samples.
Q3: What is the typical lead time for an order?
A: Lead time depends on quantity and complexity. For standard sizes, it is usually 15–25 working days. Custom orders may take 20–35 working days. We can expedite for urgent projects.
Q4: Do you provide certificates of material and testing?
A: Yes, we provide mill test certificates (MTC) for each batch, as well as third-party inspection reports if required. We also offer hydrostatic testing, eddy current testing, and other non-destructive tests.
Q5: How do you ensure the fin bonding quality?
A: We use high-frequency welding and extrusion processes that create a strong metallurgical bond. The bond strength is regularly tested via push-out tests and shear tests. Our quality control includes 100% visual inspection and random sampling.
Q6: What is the maximum operating temperature for your fin tubes?
A: It depends on the material. Carbon steel tubes can handle up to about 450°C, stainless steel up to 800°C, and alloy steel up to 650°C (higher with special grades). Please consult our engineers for your specific temperature range.
Q7: Can you provide surface coatings for corrosion protection?
A: Yes, we offer galvanized, aluminized, and epoxy coatings. For high-temperature applications, we recommend aluminized or stainless steel fins. Let us know your environment, and we will suggest the best option.
Q8: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and D/P for regular customers. Payment terms can be negotiated for large or repeat orders.
