Flanges Analysis for Energy Sector

HPC-Competence Center

Galician Supercomputing Center (CESGA) is a public HPC Center; bringing HPC, High bandwidth communications, storage, and advanced services to the Galician research community, Galician university academic system, the Spanish National Research Council (CSIC) and industry, particularly small and medium enterprises (SMEs). It aims to contribute to the advancement of science and technology, through research and application of HPC and other information technology resources for the benefit of society as a whole.


The Enterprise

Established in the nineties, TEXAS CONTROLS is a Spanish SME with ~37 employees dedicated to instrumentation, tightening, sealing and eolic prospection. Its main customers are energy generation and oil&gas companies. It is the only Spanish enterprise specialized in tighten and sealing, which is a must-have in oil and gas industries, where extreme pressures and temperatures are reached in pipes, heat exchangers or reactors, and economic and environmental costs are always high or irreparable in case of leaks in critical facilities.


How HPC makes the difference

To achieve maximum quality tightening process, it ́s crucial to analyse with maximum precision flanged joints‘ behaviour and acquire knowledge on how elastic interactions between elements take place. Texas controls had used simulation previously, but not with such high computational demands as needed in this complex modelling. They needed a detailed mechanical analysis to gather precise information about the stresses and deformations which are present in joint elements, in order to identify the right tightening parameters that make it perfect. This challenge was not feasible with their own resources, so CESGA provided infrastructure to make this a reality. The analysis showed some misbehaviours in the flanged joints that may lead either to a tightening process redesign which would meet such demanding requirements, or to completely rejecting the original design. TEXAS CONTROLS CEO, Mr Frank Fernandez, stated that without CESGA´s HPC infrastructure it would have been impossible to face the challenge and discover as much information about what really takes place in a flanged union, the collaborations helped bring much-needed expertise to build more quality products and services.
