Construcción de un horno eléctrico para realizar tratamiento térmico de alivio de tensión a la sección roscada de tubos grado l80 de 3½ pulgadas de diámetro en la Empresa SERTECPET

Abstract

This thesis deals with the construction of an electric furnace designed to carry out the tension relief heat treatment in the threaded section of 1.80 grade pipes of 3½ inches of diameter in SERTECPET Company. This project comes from the need to optimize the manufacturing processes and improve the quality of the products, therefore, the objective is focused on building an electric furnace for the tension relief heat treatment of the threaded section of 1.80 grade pipes of 3½ inches of diameter in the production plant of SERTECPET company. During the progress of the research, it was diagnosed the problem, which allowed to understand that SAMO THERMAL electric furnaces applied in SERTECPET company to perform tension relief heat treatment to the threaded section of 1.80 grade pipes do not cover the production needs of the rectification plant due to the design and the capacity of pipes per chamber. This situation is pretended to be improved with bases supported in the theory, for which several researches, such as articles, books or study thesis, were analyzed. Once the information was expanded, it was necessary to develop the construction of the electric furnace for heat treatment of tension relief. for which it was perform the thermal analysis of the furnace, with the calculations of thermal loads of the air, of the piping, and the thermal resistance of the walls or doors was evaluated. In addition, the design of the electric furnace was shown with its plans and designs. Summarizing, the specific requirements and variables that impact directly on tension relief were established, supplying a solid basis for the development of the furnace.
