First, common boiler stainless steel pipe series models
1. 304 stainless steel pipe: 304 stainless steel pipe is a commonly used stainless steel material with excellent corrosion resistance and oxidation resistance. It is suitable for boiler systems under normal temperatures and pressures and is often used to manufacture boiler heat exchange pipes, flue gas discharge pipes, etc.
2. 316 stainless steel pipe: 316 stainless steel pipe is a stainless steel material with higher corrosion resistance. It is widely used in marine environments and chemical industries due to its excellent corrosion resistance in environments containing chloride ions. For high-temperature and high-pressure boiler systems, 316 stainless steel pipes are also a reliable choice.
3. 321 stainless steel pipe: 321 stainless steel pipe has good corrosion resistance in high-temperature environments and can withstand higher temperatures and pressures. Due to its excellent heat resistance and anti-oxidation properties, it is widely used in high-temperature gas burners, furnaces, and boiler fuels.
4. 2205 stainless steel pipe: 2205 stainless steel pipe is a duplex stainless steel material with high strength and excellent corrosion resistance. It is suitable for boiler systems requiring higher strength and corrosion resistance, such as chemical, petroleum, and offshore engineering fields.

Second, how to choose suitable boiler stainless steel pipes
1. Select materials according to the working environment: Different boiler systems have different working environments, such as temperature, pressure, corrosiveness, etc. When selecting boiler stainless steel pipes, the appropriate material should be selected according to the specific working environment. For example, in high temperature, high pressure, and highly corrosive environments, stainless steel materials with good corrosion resistance and heat resistance should be selected.
2. Consider the balance between cost and performance: When selecting boiler stainless steel tubes, in addition to considering the performance of the material, you also need to consider cost factors. Different stainless steel materials have different prices and different properties. Therefore, when making a choice, it is necessary to comprehensively consider performance requirements and economic realities, and look for materials with high cost performance.
3. Pay attention to the weldability of the material: For boiler systems, welding is a common connection method. Therefore, when selecting boiler stainless steel pipes, the weldability of the material also needs to be considered. Some stainless steel materials are prone to intergranular corrosion at high temperatures, which affects the quality and performance of welded joints. Therefore, when selecting materials, pay attention to their welding properties
