Atenci\u00f3n: La norma DIN 17175 ha sido retirada oficialmente y sustituida por la norma europea vigente EN 10216-2.<\/span><\/p>\n

Reglamento t\u00e9cnico y campo de aplicaci\u00f3n<\/h2>\n

Esta norma establece las condiciones t\u00e9cnicas de suministro para tubos sin costura, incluidos los elementos de sistemas colectores, fabricados con los grados de acero resistentes al calor que figuran en la tabla siguiente. Los productos que cumplen con estos requisitos est\u00e1n destinados a su uso en plantas de generaci\u00f3n de vapor, tuber\u00edas de alta temperatura y recipientes que trabajan bajo presi\u00f3n. La temperatura m\u00e1xima de funcionamiento es de 600 \u00b0C, aunque la tolerancia real viene determinada por una combinaci\u00f3n de factores: la intensidad de la carga mec\u00e1nica, la presi\u00f3n interna y el grado de exposici\u00f3n a medios oxidantes.<\/p>\n

Bajo el concepto de \u00abaceros resistentes al calor\u00bb en el contexto de esta norma, se entienden las aleaciones que conservan caracter\u00edsticas f\u00edsico-mec\u00e1nicas estables, incluida la resistencia a la fluencia, durante un uso prolongado en condiciones de altas temperaturas.<\/p>\n
