Long-term corrosion of steel structure quality inspection
Now, for the design and construction of steel structures, the quality of life system is adopted. In recent years, the government has set forth a clear life expectancy for the design and manufacture of steel structures (such as bridges). Therefore, no matter what kind of anti-corrosion technology steel structure to take protective treatment, in the process of making or maintaining it, we must conduct professional and strict quality inspection and supervision. In the spirit of being responsible for the steel structure project, the project users, construction parties and professional supervision parties should attach great importance to this important link.
For each anti-corrosion
construction process, we must put forward a clear quality and technical specifications. Such as blasting grade or manual pretreatment grade during pretreatment of steel structure, environmental requirements for anti-corrosion construction, paint construction procedure, bonding performance and thickness of the correct choice of paint coating or thermal spray coating on-site sampling inspection, sampling Corrosion simulation environment, the coating appearance inspection, etc., are required by someone responsible.
Regardless of the construction side, or the user of the project, the anti-corrosion coating for strict quality testing, we must use more sophisticated detection methods and equipment, and at present, many steel structure manufacturers or engineering users on how to detect the construction The performance of anti-corrosion coating, the basic no good attention, and some simply simply no testing equipment or conditions. This is one of the main reasons why many disasters, such as life-long service life of steel structures, have been greatly shortened and may be damaged.
V. CONCLUSION Through the above analysis, we can draw the following conclusions: 1. Nowadays, the society has begun to seriously treat the systematic long-term preservation of steel structures, which is closely related to the safe operation of steel structures and the guarantee of life expectancy. 2. To strengthen the construction and maintenance of steel structures in the process of construction management and supervision of anti-corrosion, the project uses the party, the construction side and the professional supervision side is crucial. 3 in the steel structure design and production process, there must be professional anti-corrosion engineering and technical personnel and experts in the participation or guidance. 4. In China, arc spraying long-term anti-corrosion technology is an emerging technology developed in recent years, has attracted more and more attention, and the organic combination of coating technology, will have more market advantages.
