Laser Welded Carbon Steel Finned Tube
Laser Welded Carbon Steel Finned Tube’s welds are dense and high-strength, capable of withstanding higher pressures and tensions.
What is Laser Welded Carbon Steel Finned Tube?
Laser-welded carbon steel finned tubes primarily consist of a base tube and fins. The base tube, serving as the primary heat transfer channel, is typically made of high-quality carbon steel. This material not only offers excellent pressure resistance and toughness, but also maintains stable operation in high-temperature and high-pressure environments. The base tube’s diameter, wall thickness, and length are designed based on specific application scenarios and operating requirements to ensure optimal load-bearing capacity and heat exchange efficiency.
Advantages of Laser Welded Carbon Steel Finned Tube
Small Heat-Affected Zone: Laser welding concentrates heat, minimizing the thermal impact on the fins and base tube. This effectively prevents changes in the base material’s microstructure and properties, such as grain growth and reduced hardness, caused by overheating, thereby preserving the original properties of the base material.
High Welding Precision: The laser beam can be precisely focused and positioned, enabling high-precision welding. The weld seam is narrow and uniform, and the weld position is accurate, ensuring the dimensional accuracy and appearance quality of the finned tube.
Good Sealing: During laser welding, the surface tension of the molten metal in the molten pool prevents spattering and loss, resulting in a well-formed weld seam and excellent sealing, effectively preventing leakage.
Material and Cost Advantages of Laser Welded Carbon Steel Finned Tube
Material Savings: The base tube thickness can range from 0.8-1.5 mm, and the fin thickness can range from 0.3-1 mm, significantly reducing material costs compared to other processes.
Weldability: Fins and base tubes of different materials can be welded together, such as stainless steel fins to carbon steel base tubes, with reliable weld quality.
Laser Welded Carbon Steel Finned Tubes Offer High Production Efficiency
High Welding Speed: Laser welding concentrates energy, resulting in significantly faster welding speeds than traditional welding methods, typically reaching several meters per minute or even higher. This significantly improves production efficiency and is particularly suitable for large-scale production.
High Level of Automation: Laser welding equipment can be easily integrated into automated production lines, enabling automated control of the welding process, reducing manual intervention, improving production efficiency and product quality consistency, and lowering labor costs and labor intensity.
Laser Welded Carbon Steel Finned Tube is energy-efficient and environmentally friendly
High Energy Efficiency: Laser welding concentrates energy in the welding area, minimizing energy loss. Compared to traditional welding methods, it offers higher energy efficiency and effectively reduces energy consumption.
Low Environmental Pollution: Laser welding eliminates the need for large amounts of welding materials and shielding gas, generating less waste slag, exhaust gas, and other pollutants, resulting in minimal environmental pollution.
Laser Welded Carbon Steel Finned Tube Application Areas
HVAC:
In the evaporator and condenser of air conditioning systems, carbon steel laser-welded finned tubes provide efficient heat exchange, improving the energy efficiency of the air conditioning system and enabling rapid cooling or heating. Their corrosion resistance also ensures stable operation over long periods of use.
Industrial Waste Heat Recovery:
In waste heat recovery systems in industries such as steel, chemical, and power generation, carbon steel laser-welded finned tubes can be used to transfer heat from high-temperature exhaust gases or wastewater to other media, achieving energy recovery and reuse, reducing energy consumption and improving the company’s economic and environmental benefits.
Petrochemical Industry:
Used in various heat exchangers and coolers in petrochemical production, such as cooling systems for tubular reactors and reflux condensers for distillation towers, they provide reliable heat transfer performance under harsh operating conditions such as high temperature, high pressure, and corrosive media, ensuring stable operation of the production process.
Boiler Industry:
As the primary heat exchange element in industrial boilers and residential wall-mounted boilers, they quickly transfer heat generated by fuel combustion to the media, improving boiler thermal efficiency and reducing energy waste. Their excellent corrosion and wear resistance also extend the boiler’s service life.
