In September of 2014, Roc-Master successfully completed the Hydrostatic test on API 10000Psi & API 15000Psi flanges and the leakage test which lasts 15 hours. It is the first time that we provide API Flanges and the whole sets (including spectacle blinds, bolts, gaskets) to MODEC’s Petrobras FPSO Cidade de Caraguatatuba MV27 project on such a large scale.
