Tipos de fabricación de tuberías y revestimientos J55/K55 según API 5CT
Las tuberías J55/K55 se pueden fabricar sin costura o con soldadura EW. En la mayoría de los casos, las tuberías se fabrican sin costura.
Métodos de tratamiento térmico para tubos J55/K55
PSL1: J55 y K55 son iguales (condición de entrega laminada en caliente sin tratamiento térmico);
PSL2: Las tuberías y los tubos J55 y K55 deben ser normalizados en toda su longitud o normalizados y templados; si están engrosados, deben engrosarse después de normalizarlos o normalizarlos y templarlos.
Prueba de impacto Charpy
Cuerpo de tubería y de revestimiento:
PSL1: No hay diferencia entre J55 y K55;
PSL2: J55 y K55 requieren una energía de impacto horizontal mínima de 20 J para una muestra de tamaño completo y de 27 J para una muestra de tamaño completo.
Acoplamientos: Las pruebas de impacto J55 y K55 deben realizarse con una energía de impacto transversal mínima de 20 J para muestras de tamaño completo y de 27 J para muestras de tamaño completo en la dirección longitudinal.
Prueba no destructiva
J55/K55 PSL1: No hay requisitos obligatorios para la prueba NDE.
J55/K55 PSL2: Todos los grados de tuberías se deben inspeccionar para detectar imperfecciones longitudinales en las superficies externas e internas para que sean aceptadas por el nivel L4 utilizando uno o más de los siguientes métodos:
a) Pruebas ultrasónicas de acuerdo con la norma ISO 9303 o ASTM E213;
b) Pruebas de fuga de flujo de acuerdo con la norma ISO 9402 o ASTM E570;
c) Pruebas de bobina concéntrica de corrientes de Foucault de acuerdo con la norma ISO 9304 o ASTM E309;
d) Para la superficie externa de la tubería, inspección de partículas magnéticas de acuerdo con la norma ISO 13665 o ASTM E709.
