Details description
Core Product Advantages
High-Efficiency Heat Transfer Performance
The inner wall features a precisely rolled spiral or straight-tooth thread structure, increasing the surface area by over 30%. This enhances the fluid turbulence effect, improving heat transfer efficiency by 40%-60% compared to smooth tubes and significantly reducing energy consumption.
Pressure and Corrosion Resistance
Using materials such as TP2 copper, 304/316L stainless steel, and carbon steel, combined with an inner wall anti-oxidation coating process, it can withstand high pressure (10MPa+), high temperature (300℃), and corrosion from refrigerants and water vapor, with a lifespan exceeding 15 years.
Lightweight Design
Thin-walled precision forming technology (wall thickness 3mm-20mm) achieves lightweight design while ensuring strength, suitable for compact heat exchangers.
Customized Services
Supports customization of diameters from Φ30mm to Φ273mm and various thread parameters (height/pitch), suitable for refrigeration copper tubes, boiler heat exchange tubes, and new energy vehicle cooling tubes, etc.
Application Areas
Refrigeration Industry: Air conditioner evaporator/condenser tubes, refrigerator refrigerant circulation tubes.
Energy and Power: Power plant boiler high/low-pressure heat exchange tubes, waste heat recovery spiral tubes.
Automotive Manufacturing: Engine cooling tubes, battery cooling tubes, turbocharger intercoolers.
Chemical Equipment: Reactor coils, liquid heating/cooling circulation systems.
New Energy: Photovoltaic polysilicon cooling tubes, hydrogen fuel cell thermal management components.
Technology and Quality Assurance
Advanced Technology: Uses high-speed rotary swaging forming, online annealing, and inner wall cleaning technology.
Strict Testing: Passes eddy current flaw detection, pressure testing, metallographic analysis, etc., providing reports on compressive strength and heat transfer performance.
Fast Delivery: Fully automated production lines support small-batch trials and mass production, with fast delivery times.
