The UNE 192011-3 standard has been drawn up as a guide for the periodic inspection of pressure equipment and facilities included in ITC-EP 3, which applies to the installation, periodic inspections and repairs of all the equipment included in the regulation on pressure equipment installed in oil refineries and petrochemical plants.
The provisions of ITC-EP 3 will be applied to oil refineries, to petrochemical plants that process oil distillates and waste, and to depots where crude oil, intermediate and refined products are stored.
The following are considered part of a refinery and petrochemical plant: manufacturing units, pumping and transfer stations, piping and operating lines, loading stations, oil separators, plants for mixing and adding chemicals, flares and auxiliary installations, as well as other complementary installations necessary for the refinery to operate.
The standard includes seven Annexes that help with its implementation: determination of equipment class, inspection, marks and identification, frequency of inspections, evaluation methods and criteria, etc.
