The appropriate solution for the leakage of stainless steel heat exchange tube bundles should be selected based on the leakage location, medium characteristics, and operating conditions. There is no distinction between emergency leak prevention and permanent repair of shutdown. Emergency leak stop without stopping the machine (operated under pressure): 1. Fixture injection sealing (applicable for single tube leakage) Customize arc-shaped fixtures to wrap around leakage points → inject high-temperature resistant [...]
Stainless steel heat exchange tubes need to be replaced in the following situations, otherwise it will affect their use! 1. Serious physical damage Corrosion perforation or wall thickness reduction exceeding 5%: Visible holes appear on the pipe wall, or local thinning exceeding 5% of the original thickness is detected during testing (such as the original 2mm wall thickness being reduced to below 1.9mm). Continuing to use at this time may [...]
If there are defects on the surface of stainless steel heat exchange tubes, they need to be repaired, and the repair method depends on the degree of damage. We can classify different injuries into several levels: Bronze level (shallow scratch repair) Use 800 grit sandpaper as a scrubbing towel and rub it along the metal pattern until it reflects light; The polishing paste is used as a facial mask. After [...]
The highlights of using stainless steel heat exchange tubes mainly focus on four aspects: material, heat transfer efficiency, resistance to manufacturing, and maintenance. 1. Material selection is important For food and medicine, choose 316L for eye closure: soaking in salt water for 5 years without rust spots, it is as easy to resist corrosion as soaking in a bathhouse. High temperature boiler on 310S: able to withstand 900 ℃ barbecue [...]
Whether the stainless steel heat exchange tube can be repaired depends on the degree of damage! The specific repair plan is as follows. If it is mild or localized damage, welding repair or polymer repair agents can be used. Welding repair is suitable for scenarios with crack length ≤ 30% of pipe diameter or pitting corrosion pits (depth ＜ 1mm). TIG argon arc welding is preferred, combined with ER309L stainless [...]
What is the yellow color on the surface of stainless steel heat exchange tubes? This yellow stain is usually caused by high-temperature oxidation, impurity deposition, or material issues. High temperature oxidation refers to the thickening of the surface oxide film on stainless steel heat exchange tubes caused by long-term high-temperature operation, forming a yellow or brown oxide layer (commonly seen when 316L material deteriorates or alloy elements are insufficient); Oil [...]
