Product Characteristics
SEAMLESS COLD-DRAWN LOW-CARBON STEEL HEAT-EXCHANGER AND CONDENSER TUBES
Scope of Application
Suitable for steel pipes used in tubular heat exchangers, condensers, and similar heat transfer equipment.
- Extreme Heat Transfer Performance: Adopting high-precision rolling technology and special tube design (such as threaded tubes, finned tubes), the heat transfer coefficient is increased by more than 40% compared with ordinary straight tubes. It can quickly realize heat transfer between media, shorten the thermal cycle, and help improve the overall operating efficiency of equipment by 25%-50%, accelerating and enhancing the production process.
- Superior Damage Resistance and Durability: Selected high-quality special materials such as carbon steel, cupronickel alloy, and Hastelloy, and processed through multiple strengthening procedures including annealing and pickling. It can withstand high temperatures (up to 600℃), high pressures (up to 30MPa), and multi-medium corrosive environments. Under normal working conditions, the service life is as long as 10-15 years, significantly reducing equipment maintenance and replacement costs.
- Energy-Saving and Consumption-Reducing Advantages: Optimized the distribution of flow fields inside the tube to reduce the flow resistance loss of media. Combined with the lightweight tube wall design, it reduces the overall energy consumption of equipment while ensuring structural strength. It can help enterprises reduce energy expenditure by 20%-30% annually, complying with the national policies on energy conservation and emission reduction.
- High Adaptability and Flexibility: Full-specification customization is supported. The tube diameter (6mm-50mm), length (1m-12m), and connection methods (flange, thread, welding) can be adjusted according to customer needs. It is compatible with various heat exchangers such as shell-and-tube, plate-type, and double-pipe heat exchangers, without the need for large-scale modification of existing equipment, enabling convenient installation and strong adaptability.
- Industrial Manufacturing Field: In the waste heat recovery of iron and steel smelting, equipment cooling in mechanical processing, and coating drying systems in automobile manufacturing, heat exchanger tubes can efficiently realize the recovery and transfer of heat. They not only reduce energy consumption in industrial production but also ensure the stable operation of equipment and improve the precision of production and processing.
- HVAC Industry: As the core heat transfer component of central air conditioning and floor heating systems, heat exchanger tubes can quickly complete heat exchange between cold and hot water, accurately control indoor temperature. They are suitable for various places such as residential communities, commercial office buildings, hotels, and shopping malls.
- Petrochemical Industry: In processes such as crude oil heating, oil product cooling, and chemical reaction heat exchange, heat exchanger tubes can withstand high-viscosity and strong-corrosive media, ensuring stable heat transfer efficiency and guaranteeing the safety and efficiency of production processes such as petroleum refining and chemical synthesis.
- Biopharmaceutical Industry: Used in scenarios such as constant-temperature reactions in pharmaceutical production and temperature control for vaccine cold storage, heat exchanger tubes are made of food-grade and pharmaceutical-grade materials with smooth surfaces that are easy to clean. They can avoid medium contamination and meet the strict requirements for hygiene and precision in the biopharmaceutical industry.
