Standard interpretation: EN 10216-1 and EN 10216-2

EN 10216 series of standards: EU standards for boilers, smoke tubes and superheater tubes

In recent years, with the advancement of industrialization, the demand for high-quality steel pipes has continued to increase, especially in the fields of boilers, smoke tubes, superheater tubes and air preheater tubes. In order to ensure the safety, durability and performance of these products, the EU has formulated the EN 10216 series of standards to clarify the requirements and uses of steel pipes. This article will focus on two important EU standards, EN 10216-1 and EN 10216-2, focusing on their application, main steel pipe grades and precautions when using them.

Standard interpretation: EN 10216-1 and EN 10216-2

EN 10216-1 and EN 10216-2 are EU standards for steel pipe manufacturing and quality requirements, specifically for different types of steel pipes and their use scenarios. EN 10216-1 mainly involves the manufacturing requirements of seamless steel pipes, especially for applications such as high-pressure boilers and heat transfer pipes that are subjected to high temperature and high pressure conditions. EN 10216-2 focuses on specific alloy steel pipes, such as those widely used in the chemical and power industries. These standards specify the chemical composition, mechanical properties, dimensional tolerances and necessary inspection items of steel pipes to ensure the reliability and safety of the produced steel pipes in harsh environments such as high temperature and high pressure.

Main uses

Steel pipes produced according to the EN 10216 series standards are widely used in boiler water pipes, smoke pipes, superheater pipes, air preheating pipes and other fields. These steel pipes are usually used to withstand high temperature, corrosive gases and high-pressure steam working environments. Therefore, they need to have high strength, excellent corrosion resistance and good thermal conductivity.

In boiler equipment, EN 10216 series steel pipes are used for boiler water pipes and smoke pipes to conduct heat and discharge exhaust gas. Superheater pipes and air preheating pipes are also important application areas of this series of steel pipes. Their role is to effectively improve the thermal efficiency of boilers and reduce energy consumption.

Common steel pipe grades

In the EN 10216 series of standards, common steel pipe grades include: P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10, etc. These grades of steel pipes have different chemical compositions and physical properties and are suitable for different working environments. For example, P195GH and P235GH steel pipes are often used in boiler equipment, while 13CrMo4-5 and 10CrMo9-10 are mainly used in chemical equipment and high temperature and high pressure environments.

Precautions for use

Although the EN 10216 series steel pipes have excellent performance, some precautions should still be taken when using them. First, users should choose the appropriate steel pipe grade according to the specific application environment to ensure the safe operation of the pipeline system. Secondly, the steel pipe needs to be inspected regularly during use, especially in high temperature and high pressure environments, and attention should be paid to whether the pipe has corrosion, cracks or other damage. Finally, in order to extend the service life of the steel pipe, regular cleaning and maintenance should not be ignored.

The EN 10216-1 and EN 10216-2 series of standards provide high-quality steel pipe products for industrial production, ensuring the safety and stability of key equipment such as boilers, smoke pipes, superheater tubes, etc. By following these standards, the operating efficiency of the equipment can be maximized and the continuous and stable operation of industrial production can be ensured.
