化工压力容器档案是指设计、制造和安装使用过程中所形成的技术文件材料,它属于产品档案或设备档案这个范围。就化工压力容器(以下简称压力容器)而言,可以分为贮运容器、换热容器、反应容器和分离容器,其使用范围相当广泛。它是工业中常用的设备,特别是石油与化学工业更是离不开它。因为许多石油与化工的生产工艺过程都是在高温、高压或低温负压下进行的。这些过程所用的设备绝大部分都是压力容器。另外,每一个使用民用液化罐的家庭,也都有一个小型的压力容器。这也说明了压力容器使用的广泛程度。
Chemical pressure vessel file refers to the design, manufacture and installation of the use of technical documents formed during the material, it belongs to the product file or equipment file this range. For chemical pressure vessels (hereinafter referred to as pressure vessels), can be divided into storage containers, heat exchangers, reaction vessels and separation vessels, the use of a wide range. It is commonly used in industrial equipment, especially the oil and chemical industry is inseparable from it. Because many petroleum and chemical production processes are carried out under high temperature, high pressure or low temperature negative pressure. The equipment used for these processes is mostly pressure vessels. In addition, every household that uses civil liquefaction tanks also has a small pressure vessel. This also shows the wide range of pressure vessels used.
