Precision Engineered Casting Boiler Tube Shield with High Refractoriness

The innovative fins implemented on our advanced boiler superheater tubes are pivotal structural components designed to significantly boost heat transfer efficiency. These fins, crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, are indispensable for expanding the heating area, thereby optimizing the heat transfer rate. Renowned for their superior resistance to high temperatures and corrosion, they guarantee reliable and sustained performance over the long term. During the fin manufacturing process, careful consideration is given not only to cost-effectiveness but also to adopting cutting-edge processing technologies.

The strategic use of these fins effectively addresses the critical issue of scaling on the inner walls of boiler superheater tubes. Scaling significantly diminishes the heat transfer area, leading to a drop in heat transfer efficiency. By integrating fins, not only is this challenge mitigated, but there is also a marked reduction in boiler operating costs due to decreased fuel consumption and enhanced boiler performance.


Functional characteristics of boiler tube fins:
1. Increase heating area: By ingeniously amplifying the surface area on the tube's exterior, the fins enable the smoke circulating between them to transmit heat more effectively to the internal medium, typically steam. This unique design dramatically augments the heat transfer capacity per unit volume, ensuring optimal performance.

2. Improve heat transfer efficiency: By enlarging the heating area, the fins contribute to a significantly higher heat transfer coefficient. This enhancement ensures that the heat transfer process is not only swift but also remarkably efficient, which is essential for maintaining top-notch boiler efficiency and precise steam temperature control.

3. Diverse structural forms: These fins exhibit exceptional versatility, available in spiral shapes that envelop the steel pipe continuously, securely fixed by high-frequency welding to prevent detachment. Alternatively, they may be crafted as separate circular sheets, which, despite being subjected to singular forces, can alleviate issues of dust accumulation and dead corners in specific applications.

4. Membrane wall application: In water-cooled wall structures, the application of finned tubes is referred to as a 'membrane wall.' This not only enhances the heating surface but also markedly improves sealing performance, thereby minimizing boiler air leakage and elevating overall thermal efficiency.

6. Welding strength and stability: Premium quality finned tubes are subjected to rigorous welding strength tests, such as ensuring a pull-out force exceeding 200MPa. This meticulous testing regimen guarantees the stability and reliability of the welded components, ensuring unparalleled performance.

7. Specific design applications: Exemplified by the double H-shaped finned tubes, these uniquely designed components offer unparalleled heating surfaces and superior heat transfer efficiency. They are ideally suited for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, surpassing ordinary finned tube capabilities.
