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 [...]
There are different methods for cutting stainless steel heat exchange tubes, each with its own advantages and disadvantages. It is necessary to choose the appropriate method to ensure that the performance of the cut tube is not affected. Grinding wheel cutting → conventional cutting, batch processing Easy to operate, low cost, fast cutting speed, but may produce burrs that require further processing, and sparks that require protection. Laser cutting → [...]
The lower temperature tolerance range of stainless steel heat exchange tubes is determined by the material type! There are significant differences in the performance of heat exchange tubes made of different materials in low-temperature environments. 304 stainless steel heat exchange tube: It can maintain good toughness in extremely low temperature environments of -196 ℃ and is suitable for cryogenic equipment such as liquefied natural gas (LNG) storage tanks. Its austenitic [...]
What are the difficulties in quality control during the processing of stainless steel bright tubes? 1. Surface defect control: Cold processing can easily produce black spots and scratches, so it is necessary to strictly clean the rollers and molds; Impure annealing atmosphere may lead to oxidation color difference, and real-time monitoring of gas purity is required. 2. Dimensional accuracy guarantee: The wall thickness tolerance after cold rolling needs to be [...]
