在化工设备的安装施工中,焊接工程举足轻重,它不仅决定着化工设备的运行状态,还决定着化工设备的使用寿命。化工设备是化学工业生产中所用的机器和设备的总称,化工生产中为了将原料加工成一定规格的成品,往往需要经过原料预处理、化学反应以及反应产物的分离和精制等一系列化工过程,实现这些过程所用的机械,常常都被划归为化工设备。因此,化工产品的质量、产量和成本,在很大程度上取决于化工设备的完善程度,而化工机械本身的特点必须能适应化工过程中经常会遇到的高温、高压、高真空、超低压、易燃、易爆以及强腐蚀性等特殊条件。
In the installation and construction of chemical equipment, welding engineering plays a decisive role, which not only determines the operating status of chemical equipment, but also determines the service life of chemical equipment. Chemical equipment is the general name of machinery and equipment used in the production of chemical industry. In chemical production, in order to process raw materials into finished products with certain specifications, it is often necessary to go through a series of chemical processes such as pretreatment of raw materials, chemical reaction and separation and purification of reaction products, The machinery used to carry out these processes is often classified as chemical equipment. Therefore, the quality, output and cost of chemical products depend largely on the perfection of chemical equipment. The characteristics of chemical machinery itself must be able to adapt to the high temperature, high pressure, high vacuum, ultra-low pressure , Flammable, explosive and corrosive and other special conditions.
