在石油化工行业中,有大量的设备是在腐蚀工况下运行的,对于这些设备都必须采用较好的耐蚀性材料,通常是采用不锈钢,然而由于不锈钢价格很贵。正因为如此,复合板在近年来得到了广泛的应用,以取代某些环境下采用纯不锈钢,达到既能防腐又能降低设备造价的目的。我厂是从1987年开始用复合板制造压力容器的,经过几年来在制造过程中的不断摸索和总结,得到了一些经验,特别是对制造过程中某些环节的控制非常关键,下面就将关键环节施工时要注意的事项介绍给大家,供同行们参考。
In the petrochemical industry, a large number of equipment is operating under corrosive conditions. For these equipment, good corrosion resistance materials are usually used, but stainless steel is often used, however, because stainless steel is expensive. Because of this, the composite board has been widely used in recent years to replace the pure stainless steel in some environments, to achieve both anti-corrosion and lower equipment costs. Our factory has been manufacturing pressure vessels with composite plates since 1987. After several years of continuous exploration and conclusion in the manufacturing process, we have gained some experience, especially for the control of some aspects of the manufacturing process. The key aspects of construction should pay attention to the matter introduced to you for your colleagues for reference.
