Stainless steel heat exchange tubes are generally used in heat exchangers and placed in the cylinder for the exchange of the two media. So do you know what are the standards for stainless steel heat exchange tubes? Mingxin Stainless Steel will tell you below!
Stainless steel heat exchange tubes have the following five standards:
1. Appearance
The appearance of stainless steel heat exchange tubes should meet the relevant standards, and the surface of the pipe fittings should be smooth, free of cracks, depressions, scales, etc., and should also meet the requirements of relevant standards for size and weight.
2. Materials
Stainless steel heat exchange tube materials generally use 316L, 304, 321 and other stainless steels. The chemical composition, mechanical properties, and physical properties of these materials have corresponding national standards, such as ASTM A240, ASTM A276, and ASTM A312.
3. Technology
The manufacture and use of stainless steel heat exchange tubes must comply with relevant technical standards, such as manufacturing process, welding process, heat treatment process, etc., and also meet relevant testing and inspection standards, such as pressure test, hydraulic test, X-ray inspection, etc.
4. Packaging
Stainless steel heat exchange tubes should comply with relevant packaging standards during transportation and storage. For example, measures such as moisture-proof, shock-proof, and corrosion-proof should be adopted to ensure product quality and safety.
5. Application
The application of stainless steel heat exchange tubes must meet the requirements of relevant standards. For example, in the food, pharmaceutical, chemical and other industries, it must meet the corresponding hygienic standards, and at the same time, it must meet the relevant safety and environmental protection standards.
