DIN EN 10217-2:2019-08

The EN 10217-1 to -7 series of standards contains the technical delivery conditions for electrically welded and submerged arc welded pipes with circular cross-sections made of unalloyed, alloyed and stainless steels. They are used as pressure-retaining components in plant and power plant construction. Examples of applications are: Tubes in heat exchangers (Part 2 and Part 5), tubes for elevated and lower temperatures (Part 3), tubes for low temperatures (Part 4 and Part 6), stainless tubes for the food and chemical industry (Part 7). Since liquids/gases often flow through the pipes under high pressure and therefore the liquids/gases pose a considerable hazard potential, the pipes standardized here are subject to the European Pressure Equipment Directive. Pipes complying with these harmonized standards are generally supplied with a CE mark. The concept of EN 10217-1 to -7 has been retained with the second edition compared with the previous edition of this standard. Part 2 of the series of standards has been mainly editorially revised with regard to the references and harmonization with the PED. The committee NA 021-00-09-04 UA "Rohre aus warmfesten oder kaltzähen Stählen" ("Creep-resisting tubes and tubes with low temperature properties") at DIN is responsible for Part 2.
