Abstract

JUNTA METÁLICA SERRILHADA COM PISTA DUPLA REVESTIDA COM POLITETRAFLUOROETILENO LAMINADO PARA SISTEMA DE PROTEÇçO CATàDICA EM TUBULAÇÕES. A invenção se refere a uma junta metálica serrilhada com pista dupla revestida com anéis de Politetrafluoroetileno laminado, tornado-a um isolante elétrico para ser aplicada em tubulações em substituição as juntas tipo anel Ring-Joint de resina fenólica, podendo ser enterradas, submersas em meio com água ou solução aquosa, na presença de sais, ácidos ou bases, auxiliando no sistema de proteção catódica.Knurled metal joint with double track coated with laminated polytetrafluoroethylene for pipeline cathodic protection system. The invention relates to a double track serrated metal joint coated with laminated polytetrafluoroethylene rings, making it an electrical insulator to be applied to pipes replacing the ring-type phenolic resin ring joints, which can be buried, submerged in medium with water or aqueous solution, in the presence of salts, acids or bases, assisting in the cathodic protection system.
