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.
4. Core Specifications: Flexible Adaptation to Diverse Needs

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.
