Abstract

Dispositivo para la eliminación de las tensiones residuales producidas en un tubo, por una operación de engaste de dicho tubo, en un ánima que atraviesa, de parte a parte, una placa de gran espesor, en la que el tubo está situado de tal modo que uno de sus extremos se encuentra a nivel de una de las caras de la placa, y que vuelve a salir por la otra cara de la placa, efectuándose el engaste o mandrilado por expansión y laminado del tubo al nivel de la placa, hasta una zona próxima al lugar en que el tubo vuelve a salir de la placa, denominándose esta zona del tubo zona de transición.
