Heavy Wall Large Diameter 304 Stainless 178 Od Boiler Tube

Boiler is a common heat energy conversion equipment in our life, and the boiler stainless steel tube as an important part of the boiler, plays a crucial role in it.

Material requirements:

The material requirements for stainless steel boiler tubes have unified international standards, including ASTM, JIS, etc. Among these standards, the material requirements for stainless steel boiler tubes include quality, processing hardness, mechanical properties, etc.

Chemical composition requirements:

The chemical composition of stainless steel boiler tubes is also a key requirement in the implementation standards. In addition to the general requirements for C, Si, Mn, P, S, and other elements, it also includes corresponding requirements for alloy elements, such as Cr, Ni, Mo, etc. These elements are mainly used to improve the corrosion resistance, high-temperature resistance, and other properties of stainless steel boiler tubes.

Common boiler stainless steel tube series models:

1. 304 stainless steel pipe

304 stainless steel pipe is a commonly used stainless steel material, with reliable corrosion resistance and oxidation resistance. It is suitable for boiler systems under general temperature and pressure and is often used in the manufacture of boiler heat exchange pipes, flue gas discharge pipes, etc.

2. 316 stainless steel tube

316 stainless steel pipe is a kind of stainless steel material with higher corrosion resistance. It is widely used in Marine environments and chemical industries due to its reliable corrosion resistance in environments containing chloride ions. For high-temperature and high-pressure boiler systems, 316 stainless steel tubes is also a reliable choice.

3. 321 stainless steel tube

321 stainless steel pipe has good corrosion resistance in high-temperature environment and can withstand high temperatures and pressure. Because of its reliable heat resistance and oxidation resistance, it is widely used in high-temperature gas burners, furnaces, and boiler flue.

4. 2205 stainless steel tube

2205 stainless steel pipe is a kind of duplex stainless steel material, with high strength and reliable corrosion resistance. It is suitable for boiler systems requiring higher strength and corrosion resistance, such as chemical, petroleum, and offshore engineering.

How to choose the right boiler stainless steel tube?

1. Choose materials according to the working environment

Different boiler systems' working environments are different, such as temperature, pressure, corrosion, and so on. In the selection of boiler stainless steel tube, according to the specific working environment choose the appropriate material. For example, in high-temperature high pressure, and corrosive environments, stainless steel materials with good corrosion resistance and heat resistance should be selected.

2. Consider the balance between cost and performance

In the selection of boiler stainless steel tube, in addition to considering the performance of the material, but also need to consider the cost factor. Different stainless steel material prices are different, the performance is also different. Therefore, when making a choice, it is necessary to comprehensively consider the performance requirements and economic reality, and look for materials with higher cost performance.

3. Pay attention to the weldability of the material

Welding is a common connection method for boiler systems. Therefore, in the selection of boiler stainless steel tube, but also needs to consider the weldability of the material. 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 performance.
