Estudo da aplicação da norma NR13 para vasos de pressão P190 em condomínios residenciais

Abstract

Most residential condos have an LPG (Liquefied Petroleum Gas) gas central. This central is composed of a series of pressure vessels, commonly called canisters. One of the most common is the P190 pressure vessel with capacity for 190kg / 0.454m3 of LPG. This pressure vessel is replenished locally and is rarely moved maintaining a fixed position within the LPG gas station and may, due to this characteristic of use, be classified as a stationary pressure vessel. In this situation the P190 conforms to the norm NR-13- Boilers and Pressure Vessels. The main objective of this study is to verify if there is a need for the application of the NR-13 Standard for P190 Pressure Vessels in residential condominiums. It will check if there will be safetyrelated benefits for residents and employees and will also check for overlap or contradictions of other standards in relation to NR-13. Another objective is to present a checklist for checking the current condition of the P190 pressure vessels in these gas stations. The result of the checklist should show the main items that are presented today were current standards and in the case of NR-13 what would need to be implemented for its application. In the end, the study shows that NR-13 should be applied to new projects and that old projects should be reviewed because they no longer fully meet current standards.
