Las aplicaciones de DIN 1629 son las calderas sobrecalentadas, como ferrita de espesor mínimo y tubos de acero sin costura, y como intercambiadores de calor a través de tuberías austeníticas.
LA EN 10216 COMPRENDE VARIAS PIEZAS. LAS PIEZAS QUE SON RELEVANTES PARA NOSOTROS SON LAS SIGUIENTES:
EN 10216 Parte 1: tubos sin aleación con propiedades específicas a temperatura ambiente
EN 10216 Parte 2: tubos sin aleación con propiedades específicas a temperaturas más altas
EN 10216 Parte 3: tubos de aleación hechos de acero de grano fino para cualquier temperatura
This part of EN10216 may also be applied for tubes of non-circular cross section; necessary modification should be agreed a time of enquiry and order.
Some examples:
EN 10216-1, QUALITY P235TR2 (FORMERLY DIN 1629, ST.37.0)
- P = Pressure
- 235 = minimum yield strength in N/mm2
- TR2 = quality with specified properties relating to aluminum content, impact values and inspection and test requirements. (In contrast to TR1, for which this is not specified).
EN 10216-2, QUALITY P235 GH (FORMERLY DIN 17175, ST.35.8 CL. 1, BOILER PIPE)
- P = Pressure
- 235 = minimum yield strength in N/mm2
- GH = tested properties at higher temperatures
EN 10216-3, QUALITY P355 N (MORE OR LESS EQUIVALENT TO DIN 1629, ST.52.0)
- P = Pressure
- 355 = minimum yield strength in N/mm2
- N = normalized*
* Normalized is defined as: normalized (warm) rolled or standard annealing (at a min temperature of 930°C). This applies to allqualities designated by the letter ‘N’ in the new Euro Standards.
