El tubo rayado de la caldera de alta presión interna del hilo es una clase de procesos del endophragm la línea espiral la tubería de acero inconsútil. Uso principal adentro en la pared de la refrigeración por agua de la caldera para uso general de la capacidad. Generalmente con el tubo fluorescente que las aplicaciones comparan, puede mantener la condición nuclear de la ebullición bajo condición de funcionamiento de la carga de la alta fiebre, evita así enviar la ebullición de filmación de la condición, previene el tubo para quemar, alarga la vida de servicio del tubo.
