Estudo de viabilidade de implementação do processo direto de HIP para manufatura de um bloco de válvulas

Abstract

In recent years, the oil and gas industry has been undergoing a modernization movement, in which new manufacturing processes are constantly being developed. This growing investment in new technologies makes the market increasingly competitive, forcing companies in the oil and gas sector to always be looking to optimize their processes. The present work aimed to study the possibility of applying the HIP process to manufacture valve blocks of a Pipeline End Manifolds, to the detriment of the forging process currently used. For the development of the study, a collaboration was carried out with the company Aker Solutions do Brasil Ltda., beneficiary of the results obtained. First, the theoretical references related to the subject were raised, then a 3D model was developed, focused on the HIP process, followed by the quotation of the models together with suppliers, further data analysis and comparison of the results obtained for both manufacturing methods with the study of calculation. A block integrity study was also carried out using calculation software. So, with all the data collected, it was possible to conclude that the HIP process, replacing forging and machining, is not technically and economically viable. The block integrity calculation study showed logarithmic deformation results greater than 2%, and the best quoted value for the supply of the part in HIP culminated in a final product 11% more expensive than the block from the forging.
