锅炉和压力容器之所以被世界绝大多数国家列为特种设备,实行国家安全监察,究其原因,在于这些设备既是生产和生活中广泛使用的,但又具有爆炸的危险性。前者是由设备的功能(即用途)决定的,后者是由于设备承受压力(即性质)决定的。因此,在讨论有关锅炉和压力容器的安全问题时,总是围绕“压力”进行的。目前,在一些刊物、教科书,甚至专业技术标准上、对“压力”一词的提法是多种多样的。诸如,设计压力、计算压力、工作压力、
The reason why boilers and pressure vessels are listed as special equipment by most countries in the world and the implementation of national safety supervision is based on the fact that these equipments are both widely used in production and daily life but are dangerously explosive. The former is determined by the function of the equipment (ie use), which is determined by the equipment under pressure (ie, properties). Therefore, when discussing safety issues related to boilers and pressure vessels, it is always around “pressure”. At present, there are many references to “stress” in some publications, textbooks, and even professional technical standards. Such as design pressure, calculate pressure, working pressure,
