The emergence of high frequency finned tubes has been sought after by many people. The reason why they can be widely used and promoted is mainly due to the excellent performance of high-frequency finned tubes.
The product has high production efficiency and can be wound continuously. Production; and the production cost is low, it relies on the characteristics of high-frequency welding itself – the skin effect to heat the surface of the workpiece to achieve the purpose of welding, and does not need to add any filler metal materials during the welding process.
Due to the advanced welding process, it can ensure the welding quality of high frequency finned tubes, the welding is reliable, and it can withstand the thermal shock fluctuations caused by frequent start-up and shutdown.
This product has been widely used in new high-efficiency heat transfer elements in petroleum, chemical, electric power and other industries to enhance heat transfer outside the tube, improve heat recovery efficiency, save energy and reduce consumption.
Although high-frequency finned tubes have so many advantages, users still need to pay more attention to inspections during the daily use of high-frequency welded finned tubes.
The main contents include:
1. The inlet temperature of the high-temperature exhaust has exceeded the allowable value, or has dropped to a value that is too low;
2. Whether the flow rate of the high-temperature exhaust exceeds or is insufficient;
3. Whether the flow rate of the low-temperature side is insufficient or not Too many problems;
4. Whether there is dust accumulation in the finned tube.
Avoid mistakes during daily use.
