1.ISO 9329 - 2:1997
Specifies the technical delivery conditions for seamless pipes of circular cross section with specified high temperature properties, which are suitable for high temperature piping systems. For pressure equipment, ISO/R831 and ISO5730 can be used, which replace ISO2604 - 2:1975.
2.ISO 9329 - 3:1997
Specifies the technical delivery conditions for seamless pipes of circular cross section with specified low temperature properties, which are suitable for low temperature piping systems. For pressure equipment, ISO5730 can be used, which also replaces ISO2604 - 2:1975.
3.ISO 3304:1985
Specifies the technical conditions for smooth end precision seamless steel pipes, listing the chemical composition (Table 2) and mechanical properties (Tables 3 to 6) and dimensions (Table 9), with an outer diameter ranging from 4 mm to 260 mm, and also includes tests (Tables 7 and 8). When used for hydraulic piping equipment, they can only be used in the annealed or normalized state. The second edition of this standard cancels and replaces the first edition (1975).
4. EN related standards
EN 10216 - 4:2013
Specifies the technical delivery conditions for two test categories of seamless tubes of circular cross-section made of non-alloy steel and alloy steel with specified low temperature properties. It should be noted that once this standard is published in the Official Journal of the European Union (OJEU) in accordance with Directive 97/23/EC, the presumption of compliance with the Essential Safety Requirements (ESR) of Directive 97/23/EC is limited to the technical data of the material in this standard, and it is not assumed that the material is sufficient to meet the requirements of a specific equipment. The designer or manufacturer of pressure equipment needs to evaluate the technical data specified in this material standard according to the design requirements of that specific equipment item to verify whether the ESR of the Pressure Equipment Directive is met, and also take into account the subsequent manufacturing processes that may affect the performance of the base material. This standard also references several standards such as EN 10027 - 1:1992, EN 10028 - 1:1992, etc.
5.EN 10216 - 1:2013
Specifies technical delivery conditions for seamless tubes of circular cross-section made of non-alloy high-quality steel of two qualities TR1 and TR2 with specified room temperature properties. Similar to EN 10216 - 4:2013, there are the same restrictions and requirements for compliance with the essential safety requirements of Directive 97/23/EC. Several related standards are also referenced, such as EN 10027 - 1:1992, EN 10045 - 2:1992, etc.
6.BS EN 10216 - 2:2002
This British Standard is the official English version of the European standard EN 10216 - 2:2002, and together with BS EN 10217 - 2:2002, it replaces BS3059 - 2, BS3602 - 1, BS3604 - 1 and the obsolete BS3606:1992. The allowable deviations of the outer diameter and wall thickness of the cold-drawn seamless pipe are as follows: the outer diameter deviation is ±0.5% or ±0.30mm, whichever is greater; the wall thickness deviation is ±10% or ±0.20mm, whichever is greater; the length L≤6M
