European standard seamless pipe standard

1. EN 10210 standard
The EN 10210 standard is used to manufacture non-alloy seamless steel pipes for structural use, including seamless pipes of different grades such as S235JRH, S275J0H, S355J0H, S355J2H, S355K2H. This standard specifies the physical properties (tensile strength, yield strength, elongation, etc.), chemical composition (carbon, silicon, manganese, sulfur, phosphorus and other element contents) and dimensional standards of seamless pipes. All seamless pipes should meet the requirements specified in the standards to ensure their quality and safety performance.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. EN 10216 standard
The EN 10216 standard is used to manufacture seamless steel pipes used under high temperatures and pressures, mainly used to transport steam, gases and liquids. This standard covers seamless pipes of many different materials, such as P235TR1, P265TR1, P265TR2, 16Mo3 and 13CrMo4-5, etc. The EN 10216 standard requires pipes to have high-temperature stability and corrosion resistance. It also stipulates the chemical composition, physical properties and dimensional standards of pipes to ensure that they can be used safely in high-temperature and high-pressure environments.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. EN 10219 standard
The EN 10219 standard is used to manufacture non-alloy cold-formed seamless steel pipes for structural use. Its main feature is that it has various shapes and specifications, and can be made into pipes of various shapes such as round, square, rectangular, oval and so on. This standard applies to a range of stainless steel, carbon steel and low alloy steel, such as S235JRH, S275J0H, S355J0H, S355J2H, S355K2H, etc. EN 10219 also specifies the chemical composition, physical properties and dimensional standards of steel pipes to ensure that they can meet the application requirements of structural pipes.
4. Summary
European standard seamless pipes are mainly manufactured in compliance with the three standards of EN 10210, EN 10216 and EN 10219. These standards stipulate the physical properties, chemical composition and size standards of seamless pipes, ensuring that seamless pipes have high quality and high safety performance. , can be used in various complex environments. These standards make the production process of seamless pipes more standardized, refined and efficient, providing strong support for the development of related industries.
