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 [...]
The heat transfer principle of stainless steel heat exchange tubes can be understood metaphorically as two people shaking hands to transfer body temperature. However, the heat exchange tubes transfer heat, and the hands are equivalent to stainless steel tubes. The process of shaking hands occurs between two fluids (cold water and hot water). Introduce in simple and popular language as follows: 1. Hot fluid "sticking" stainless steel pipe Suppose you [...]
Stainless steel heat exchange tubes are the "heat transfer gunners" in industrial equipment. They are responsible for transferring heat from hot potatoes to cold brothers, and they can withstand all kinds of corrosion. This thing looks like an ordinary steel pipe, but it hides the hard-core genes of stainless steel. Hard-core conduction: hot oil/steam rushes into the pipe, and the heat is transferred to the cold water along the stainless [...]
Common faults of stainless steel heat exchange tubes, such as corrosion, scaling, material and manufacturing defects, etc., are mainly caused by multiple factors such as material defects, operating environment, and process operation. 1. Corrosion problems Medium corrosion: Acidic/alkaline media (such as acid and alkali solutions in chemical production) directly corrode the tube, causing thinning or perforation of the tube wall. When the chloride ion concentration is ≥500ppm, austenitic stainless [...]
Stainless steel heat exchange tubes are common tubular heat exchange elements. In conventional heat exchange scenarios, they are standard cylindrical. However, they are not just straight tubes... In addition to straight tubes, stainless steel heat exchange tubes are classified by shape, including corrugated tubes, U-shaped tubes, coils, spiral reinforced tubes, serpentine tubes and special-shaped tubes, each of which has different characteristics. 1. Corrugated tubes: The corrugated inner or outer wall [...]
