The redness of stainless steel heat exchange tubes is mainly due to oxidation, ranging from light yellow and light blue to deep red and purple black in severe cases. Therefore, the redness of the pipe needs to be solved by acid pickling and passivation, or by electrolytic polishing. Before operation, personnel must wear acid resistant gloves/face shields. When diluting sulfuric acid, "acid in water" is strictly prohibited from reverse operation! [...]
The high pressure resistance of stainless steel heat exchange tubes is excellent, which is related to material characteristics, manufacturing processes, and design parameters. Firstly, let's talk about the material selection. 304 stainless steel heat exchange tubes are suitable for medium and low pressure scenarios up to 2.5 MPa, with low cost and stable overall performance; 316L stainless steel heat exchange tubes have stronger pressure resistance (>6.4 MPa) due to the [...]
Why do stainless steel heat exchange tubes need frequent maintenance? Many people have this question. Daily maintenance is crucial for stainless steel heat exchange tubes for the following reasons: 1. Dirt deposition leads to a sudden drop in efficiency Calcium and magnesium ions in water can quickly precipitate hard scales such as calcium carbonate (CaCO3) at high temperatures. A 1mm scale layer can reduce the heat transfer efficiency of a [...]
The storage environment of stainless steel heat exchange tubes should strictly follow industrial standards to ensure performance and structural integrity. Below are its requirements for storage environment: 1. Absolute dryness The relative humidity should be controlled below 60%, and the warehouse needs to be equipped with dehumidifiers or air conditioning systems to prevent condensation water erosion. Lay a moisture-proof layer on the ground (such as plastic film+wooden tray) to ensure [...]
The anti rust oil for stainless steel heat exchange tubes should be selected according to the working conditions and anti rust cycle. The commonly used anti rust oils are as follows. 1. Thin layer rust proof oil The oil film is thin, transparent and shiny, and forms a hard protective layer after drying. It has strong resistance to salt spray and humidity. It does not contain nitrite/heavy metals, meets food [...]
The cleaning of stainless steel heat exchange tubes requires the selection of appropriate methods based on the type of dirt, pipeline material, and operating conditions. It is mainly divided into three categories: chemical cleaning, mechanical cleaning, and comprehensive treatment, and attention should be paid to post rust prevention treatment. 1、 Select cleaning method based on dirt type 1. Scale/rust Chemical pickling: For carbon steel materials, 8% -15% sulfuric acid or [...]
