Throughout the entire industrial production process, cleaning is a crucial step for ensuring equipment efficiency, improving product quality, and achieving safe and environmentally sustainable operations. “During the 14th and 15th Five-Year Plans period, China’s industrial cleaning industry continued to expand in scale, saw an accelerated pace of technological upgrading, experienced faster progress in its green and low-carbon transformation, and its service offerings continued to evolve toward higher quality and greater sophistication. By focusing on core technological innovation, strengthening standards and talent foundations, adopting green and safety principles, and embracing the wave of digital intelligence, the industrial cleaning industry has seen a comprehensive enhancement in its core capabilities to serve strategic goals and modern industrial systems, thereby reinforcing its role as an important pillar for the high-quality development of the national economy. The innovation system is becoming increasingly comprehensive, with continuous breakthroughs in technological research. During the 14th Five-Year Plan period, China’s industrial cleaning industry’s innovation system has seen further improvement. The number of national industrial cleaning chemicals verification centers increased from 7 to 10, creating a broader R&D and verification network that provides a solid foundation for technological innovation. At the same time, continuous breakthroughs have been achieved in the development of key industry technologies and equipment, yielding fruitful results. A range of high-end equipment with independent intellectual property rights has been developed, including the WR250/320 wall-crawling robot, the XDQX-Ⅱ environmentally friendly and energy-saving modular tank cleaning device, and the QXXT-00 fully automatic cleaning device for large air-cooled radiators. The industry has also made progress in addressing practical challenges in production such as the maintenance of large-scale equipment systems, the cleaning of precision components, and the application of energy-saving and emission-reduction technologies, thereby providing strong support for **major infrastructure projects and the transformation and upgrading of the manufacturing sector. In addition, the China Industrial Cleaning Association has recommended a total of 15 projects from its member enterprises for inclusion in the Science and Technology Guidance Program of the China Petroleum and Chemical Industry Federation; 4 of these projects won science and technology awards, 4 received awards for outstanding Chinese patents, and 16 achievements were recognized as management innovation achievements. Preliminary establishment of standard matrices leads to significant improvements in personnel competence. During the 14th Five-Year Plan period, the China Industrial Cleaning Association took the lead in formulating 1 industry standard, namely the \"Technical Specifications for Chemical Cleaning Pump Stations and Related Equipment\" (HG/T 6005—2022), as well as 5 group standards; these standards cover the operational guidelines and quality inspection requirements for various cleaning applications such as gas stations, industrial equipment, and storage tanks ； Also participated in the drafting of 3 industry standards and 1 local standard. Together, these standards form a comprehensive standard matrix of \"environmental protection limits – equipment specifications – operational safety,\" which significantly enhances the standardization and professionalism of the industry. Talent is the core element that drives industry development. By continuously improving specialized training and certification systems for chemical cleaning, high-pressure water jet cleaning, PIG pipeline cleaning, and mechanical tank cleaning, and by introducing innovative teaching methods for practical operations, the China Industrial Cleaning Association has significantly enhanced the skill levels and practical capabilities of industry professionals. As the supporting organization for **vocational skill assessment centers, the association regularly updates the assessment question banks and maintains strict control over the quality of certifications, thereby supplying the industry with a large number of qualified professionals. In addition, upon the recommendation of the association, a total of 55 members passed the evaluation for junior and intermediate professional titles. A positive atmosphere that values and encourages innovation is growing stronger, and the technological driving force for the high-quality development of the industry is continuously increasing. The green transition is accelerating, and safety governance is improving steadily. The industry has always regarded green development as a key element of high-quality growth. On January 5, 2024, the \"Decision of the State Council on Amending the Regulations on the Management of Ozone-Depleting Substances\" was issued, introducing significant changes to those regulations. The China Industrial Cleaning Association actively assisted the Ministry of Ecology and Environment in advancing the phase-out of HCFC-containing cleaning agents in an orderly manner, completing the implementation of phase-out projects for 62 enterprises. At present, aside from the 4 new projects signed in 2024 that are currently under implementation, China’s cleaning industry has already phased out a total of 2,327.798 tons of HCFC-141b. The phase-out plan for HCFCs in this industry is on track to be fully completed, marking a new stage in China’s efforts to fulfill its international environmental commitments. At the same time, the research, development, and application of green industrial cleaning technologies are booming. The market for environmentally friendly cleaning agents such as water-based, biodegradable, and low-VOC ones has great potential ； Energy-saving equipment such as the 250 series of ultra-high pressure washers can reduce fuel consumption by approximately 25% through the optimization of the electrical control system, offering both economic benefits and environmental advantages. These green technologies and products reduce pollution at the source and lower environmental risks. Safety is a prerequisite for development, and the widespread use of intelligent equipment fundamentally enhances the safety level of the industry. Industrial cleaning robots have been put into practical use. The adoption of mechanical cleaning techniques such as high-pressure water jetting and dry ice cleaning, along with the implementation of standards such as the \"Technical Specifications for Chemical Cleaning Pump Stations and Related Equipment\" and the \"Quality Acceptance Standards for Water Jet Cleaning of Industrial Equipment,\" provides a solid foundation for standardizing operations and controlling risks, thereby facilitating a shift in the industry’s safety management approach toward proactive prevention. Digital and intelligent technologies are widely applied, driving continuous growth in industries. Digitalization and intelligence have become the key drivers for industrial upgrading during the 14th Five-Year Plan period. Various industrial cleaning robots and online monitoring cleaning systems are being used on a large scale in complex applications such as rust removal, sludge extraction, weld grinding, and cleaning of precision components. They are particularly used to replace manual labor in confined spaces such as flammable, explosive, and toxic storage tanks and reactors, thereby eliminating the risk of workers being exposed to high-risk environments and significantly reducing safety hazards. At the same time, they improve production efficiency through consistent quality of work. Innovation is driving the industry’s service models toward higher standards and greater sophistication. The integration of intelligent equipment with Internet of Things and big data technologies enables industrial cleaning to be more thoroughly incorporated into the intelligent operation and maintenance systems of modern large-scale production, facilitating a shift from \"passive cleaning\" to \"predictive maintenance\". This provides strong technical support for the high-quality development of high-end manufacturing industries such as petrochemicals and electronics, while also opening up new avenues for growth within these industries.
