RESUMO

In the chemical and petrochemical plants we can notice a big amount and complexity of pipings installeds, it happens due to the need to transfer and process fluids with differents pressures and temperatures and to get the operational requirements of production. A middle size petrochemical plant has among 3,000 to 15,000 tons of carbon steel pipings assembled so an adjusted sizing of these piping systems is very important. This study presents the main components, materials, design features and existing code procedures, especially under higher temperatures. It makes a comparative valuation about methods of structural solution to pipings and discussing previous concepts applied in the codes to improve these applications. In also, together a case study, presents a proposal of a methodology to sizing of pipings using Finity Element Analyse, with the goal to get a solution more safety, optimized and an economic project, in front of the large quantity of material involved in these installations.
