2. Core Product Highlights: Customized for Boiler Working Conditions, Outstanding Performance
1. Innovative Embedded Forming Process, More Stable Structure
Adopting mechanical embedded forming process: First, precisely groove the outer diameter of the base tube, guide the root of the aluminum fin strip into the groove, and then lock the fin by rolling to close the groove, forming a seamless and firm structure.
Compared with traditional welded finned tubes, it can effectively resist vibration and continuous thermal cycling, and the fins are not easy to fall off. Its temperature resistance is much higher than that of aluminum L-foot finned tubes, with a maximum applicable temperature of 450°C, perfectly adapting to the high-temperature working environment of boilers.
3. Efficient Heat Transfer, Cost-Effective Choice
The fin and tube wall maintain constant contact, with low thermal resistance, significantly improving heat transfer efficiency;
The fin is fixed along its entire length, so it will not loosen even if partially damaged, extending the service life;
It balances performance and cost, with outstanding cost-effectiveness in boiler heat transfer scenarios, making it the preferred component for efficient heat transfer.

5. Application Scenarios: Focus on Boilers, Covering Multiple Industries
As the core heat transfer component of boiler systems, it can greatly improve heat exchange efficiency and is widely used in:
Power Industry: Heat exchange systems of power plant boilers;
Petrochemical Industry: Boiler equipment in refineries and chemical plants;
Others: Industrial boiler scenarios in steel plants, fertilizer plants, etc., especially suitable for medium-high temperature working conditions with high requirements for heat transfer stability.
6. Quality Assurance: Strict Control in Multiple Links, Rest Assured to Choose
Raw Material Control: Conduct incoming inspection on base tubes and fin strips, and provide raw material mill test certificates (MTC);
Production Supervision: Conduct full-process production inspection and real-time monitoring of key links;
Finished Product Testing: Carry out water pressure test and fin bonding strength test (hanging a 3kg weight to check fin firmness);
Third-Party Certification: Support customers to entrust third-party institutions for testing to ensure products meet standards.
