Product Introduction
Product features
1. Outstanding corrosion resistance
A dense chromium oxide passivation film is formed on the surface, effectively blocking corrosive media such as chloride ions, acidic organic substances, and hydrofluoric acid. It is suitable for complex cooling medium environments such as fluorinated liquids and ethylene glycol water solutions.
It passed the 240-hour neutral salt spray test without rusting, meeting the ASTM A269 standard, ensuring long-term reliability.
2. High strength and toughness
It can withstand a working pressure of 1.6 MPa and equipment vibration, avoiding the risks of deformation or rupture.
It can adapt to extreme environmental temperatures ranging from -45°C to 60°C, meeting the diverse needs of data centers, outdoor energy storage equipment, etc.
3. Low flow resistance and efficient heat dissipation
The inner wall is smooth (roughness ≤ 0.8 μm), reducing the flow resistance of the cooling fluid and improving the heat exchange efficiency.
The thermal conductivity is high (16.3 W/m·K at 100°C), quickly conducting heat and ensuring stable equipment temperature.
4. Precision manufacturing and cleanliness
It adopts laser cutting, CNC bending, and fully automatic argon arc welding processes, with a weld seam qualification rate of ≥ 99%, and no risk of micro-pore leakage.
It has undergone ultrasonic cleaning, acid washing passivation, and ultra-high pressure flushing, with particle size ≤ NAS 8 grade, avoiding cooling fluid contamination.
5. Customized design
It supports customization of pipe diameter (3 - 50 mm), wall thickness (0.5 - 3 mm), and length, suitable for complex pipe layout.
It provides diversified interface solutions such as quick joints and flange connections, simplifying the installation and maintenance process.
