新压力容器办理使用证,确定压力容器首次检验时间时,许多使用单位误认为首次检验时间应为投入使用后第6年才进行。因新压力容器能办理使用证的均为1～2级,理所当然应为第6年进行首次检验。但根据大量的压力容器事故分析,发现在压力容器投用后的前几年和快到使用最终寿命的几年,为事故高发期。所以,在这一时期中要缩短检验周期,加强检验。对新投用的压力容器,首次检验应在投用后2至3年内进行;对球形贮罐,应在投用1年后进行。压力容器是
New pressure vessel for use permits, to determine the pressure vessel for the first time inspection, many users mistakenly believe that the first inspection time should be put into operation after the first 6 years. Due to the new pressure vessel can handle the use of certificates are 1 to 2, of course, should be the first 6 years of testing. However, according to a large number of pressure vessel accident analysis, it was found that the accident occurred a few years before the pressure vessel was put into use and almost reached the end of its service life. Therefore, in this period to shorten the inspection cycle, strengthen the test. For newly put pressure vessels, the first inspection should be carried out within 2 to 3 years after being put into use. For spherical storage tanks, it should be carried out after one year of operation. Pressure vessel is
