Abstract

duto. duto, para utilização na produção offshore de hidrocarbonetos, compreendendo: (i) duto interno eletricamente condutor: (ii) camada concêntrica externa; (iii) uma ou mais camadas concêntricas intermediárias entre o duto interno e a camada externa; e, (iv) malha concêntrica eletricamente condutora. uma simples e usualmente fina malha permite o aquecimento elétrico ao longo do duto interno de fácil fabricação, e, desta forma, aumenta significativamente a simplicidade e a eficiência do aquecimento elétrico do duto.
