When stainless steel heat exchange tubes encounter corrosive environments such as contact with media containing chloride ions or sulfides, or are subjected to high temperature, high humidity, and alternating stress conditions, protective measures should be taken from four aspects: strengthening the corrosion resistance of the material, optimizing the surface state, avoiding corrosion causes, and actively suppressing corrosion. 1. Accurately match corrosion-resistant materials Select the appropriate stainless steel grade based on [...]
Stainless steel heat exchange tubes with problems must be intercepted before leaving the factory and must not flow into the installation process. After all, heat exchange tubes need to work under pressure in an environment with alternating cold and hot temperatures, which may be corrosive. Even if a small problem is not handled properly, it may cause leakage and affect heat transfer after installation, and in severe cases, it may [...]
The process of emergency stop loss, root cause investigation, targeted repair/replacement, and system optimization prevention should be followed to deal with corrosion perforation of stainless steel heat exchange tubes. The key is to first terminate the risk of leakage, and then analyze the cause of corrosion to avoid problem recurrence Firstly, emergency stop loss and system isolation: Corrosion perforation can cause leakage of the heat exchange medium (such as mutual [...]
The burrs on stainless steel heat exchange tubes mainly come from machining processes such as cutting and welding. Burrs can affect the heat transfer efficiency and fluid flow characteristics of stainless steel heat exchange tubes, and may even lead to equipment failure. So we can't just ignore it! Mechanical deburring is the most traditional and widely used method, mainly including the following techniques: Scraper method: By using a device with [...]
There are many crack shapes in stainless steel heat exchange tubes, which are the result of complex interactions between material properties, process defects, and environmental factors. The formation mechanism and crack morphology characteristics are inherently related. From the intrinsic characteristics of the material, 304 stainless steel is prone to pitting corrosion in chloride containing environments, while 316L can significantly enhance its corrosion resistance due to its 2-3% molybdenum content. If [...]
The surface color of stainless steel heat exchange tubes is not fixed and is closely related to the material, production process, and surface treatment method. The surface of a normal stainless steel heat exchange tube should present a silver white metallic luster, which is its natural color. High quality heat exchange tubes usually have a bright and uniform color, and reflect clear light. The differences in different materials are manifested [...]
