What is EN 10216-3

EN 10216-3:2002 is a standard for the delivery conditions of seamless steel pipes for pressure purposes issued by the European Committee for Standardization. This standard specifically includes the following parts:

Non-alloy steel pipes: steel pipes with specific room temperature properties, mainly used to manufacture boiler water pipes, smoke pipes, superheater pipes and air preheater pipes.

Alloy steel pipes: steel pipes with specified high temperature properties, suitable for use in high temperature environments, covering the requirements of chemical composition, mechanical properties, manufacturing process, etc. of steel pipes.

Fine-grained alloy steel pipes: weldable alloy fine-grained steel pipes with circular cross-sections, with detailed provisions on the alloy composition, grain refinement treatment, performance indicators, etc. of the steel pipes to ensure the reliability and safety of the steel pipes under different working conditions.

This standard is mainly used to ensure that the design, manufacture and quality control of pressure equipment meet specific safety and performance standards.
