安全状况等级是在用压力容器安全性能的综合体现,是对各项检验结果综合评价得出的结论,如果安全状况等级评定的不准确,一方面可能使某些在用压力容器“带病”运行,隐患的不到及时排除,影响装置的安全运行,甚至引发爆炸事故;另一方面可能将仍可使用的容器判废,给企业带来较大的经济损失。因此要依据《在用压力容器检验规则》,通过检验,加以分析和判断,准确评定出在用压力容器的安全状况等级,从而保证在用压力容器的安全经济运行。下面就《检规》中的“安全状况等级评定”结合两个实例加以探讨: The safety status grade is a comprehensive reflection of the safety performance of the pressure vessel and is the conclusion of the comprehensive evaluation of the test results. If the assessment of the safety status grade is inaccurate, on the one hand it may cause some problems in the pressure vessel “Operation, the hidden dangers less than promptly removed, affecting the safe operation of the device, and even lead to an explosion accident; the other hand, may still be used container sentenced to waste, to bring greater economic losses to the enterprise. Therefore, based on the ”Inspection rules for pressure vessels in use“, they are analyzed and judged through tests to accurately assess the safety status of pressure vessels in service, so as to ensure the safe and economical operation of pressure vessels in use. The following on the ”regulatory“ in the ”security rating" with two examples to explore:
