Abstract
In this paper, the anti-corrosion countermeasures of chemical equipment are discussed in detail from the aspects of environment, materials, technology and design. This project intends to build a multi-dimensional path of optimization of anti-corrosion strategy from the main lines of material selection and optimization, anti-corrosion design and structural optimization and innovation, intelligent and normalized monitoring and maintenance, anti-corrosion management and training system, anti-corrosion mechanism and development and application of new technologies. This project takes China's petrochemical equipment as the research ob ject, focusing on the role of new anti-corrosion materials, surface treatment technology, intelligent anti-corrosion technology, green anti-corrosion technology, etc., in improving the anti-corrosion ability of China's chemical equipment. According to the service environment and working condition of the equipment, the improvement measures based on material composition and preparation technology are put forward for material selection and optimization. In terms of protection design and structure optimization, the equipment structure layout and protective coating were optimized by combining numerical simulation with experimental verification.
