Expansion Fire Protection Coatings Cracking Research in Winter Construction
Abstract: Expansion Fire Protection Coatings are an excellent fire protection coatings, widely used in marine platforms and other areas of fire protection. This study is based on the actual engineering projects appear in the expansion of fireproof coatings in low-temperature environment cracking problems, mainly from the performance of fire-resistant paint materials, and from the construction process, material storage and transportation, the stress of protected structures and other aspects of the analysis, to explore the low-temperature conditions of fire-resistant coating cracking possible factors, and give rational engineering recommendations.
Keywords: Passive fire protection coatings; cracking; Extreme cold

Analysis of the causes of corrosion fracture of oil injection wells in an oil field at sea
Abstract: The causes of corrosion fractures in oil injection wells in an oil field at sea are studied in depth by methods such as corrosion profiling, gold-phase tissue analysis, chemical composition analysis, and hydraulic performance analysis. The results show that the corrosion products of the surface of the column are FeCO3, MgF2 and SiO2. It is recommended to check whether the site sealer is not sealed tightly and to optimize the late acidification process.
key words: oil pipe; corrosion fracture; corrosion product; acidification

Steel Structure Module Fire-resistant Paint Center of Gravity Calculation and Analysis
Summary: Steel Passive Fire Protection Technology is widely used in modern engineering, especially in modular plant construction. Although the inflated fire-resistant coating used is light in quality, it has a certain influence on the center of gravity of the module due to its large dosing. This paper summarizes a set of relevant methods applicable to the calculation of fire-resistant paint center of gravity in steel structure modules through practice, and provides design reference for the calculation of fire-resistant paint center of gravity in future projects.
key words: expansion-type fire-resistant paint, fire-resistant paint center of gravity, center of gravity calculation
