O PIG Palito é um equipamento que utiliza sensor geométrico para fazer a inspeção interna de dutos de tamanhos variados, podendo, por exemplo, indicar pontos de corrosão severa. Diversos experimentos em bancadas de laboratório foram realizados, com o intuito de se avaliar a capacidade de medição do PIG Palito, considerando-se um disco metálico rotatório com descontinuidades usinadas em seu corpo e um único sensor para detecção dos defeitos. Até o momento, desconhece-se experimentos em bancada em que o próprio PIG Palito e seu sistema completo de sensores passam pelo interior da tubulação. Nesse sentido, o presente trabalho tem como objetivo estudar as incertezas de medição com o PIG Palito, através de experimento em laboratório, comparando os resultados encontrados pela passagem desse dispositivo, em tubulação com diâmetro nominal de 6” em PVC, com descontinuidades sintéticas feitas em impressora 3D calibradas, em laboratório acreditado pelo INMETRO. Os testes foram baseados na utilização operacional do PIG, no qual o mesmo se desloca no interior da tubulação sob diferentes condições de velocidades e com um arranjo de descontinuidades sintéticas com 5 geometrias diferentes. A metodologia empregada foi a mesma utilizada nos laboratórios de calibração de instrumentação. 10
