Super-high pressure vessel self-reinforcement treatment procedure

For the self-reinforcement process of ultra-high pressure vessels, the following aspects generally need to be considered: 1. Design principles: Ultra-high pressure vessels should have a rational structural design to minimize stress concentration as much as possible. During the processing stage, it is also important to master the appropriate processing methods and sequence in order to avoid defects such as scratches and cracks. 2. Material selection: The materials used for ultra-high pressure vessels must possess sufficient strength and toughness to withstand high pressures as well as different temperatures. Common materials include stainless steel, titanium alloy, aluminum alloy, etc. 3. Ultra-high pressure treatment: Ultra-high pressure treatment involves using high-pressure water jets to strike the surface of a container, thereby enhancing the surface hardness, corrosion resistance, and fatigue life of the material. When using ultra-high pressure treatment, it is necessary to pay attention to controlling the processing parameters, such as water pressure, nozzle spacing, nozzle angle, and water flow velocity, in order to avoid damage to the material caused by excessive treatment. 4. Surface treatment: After ultra-high pressure treatment, tiny pores or burrs may appear on the surface of the container, and surface treatment is required to prevent this from affecting the container’s service life. Common surface treatment methods include chemical polishing, mechanical polishing, electrolytic polishing, etc. Based on the above principles, a self-reinforcement treatment process plan or procedure for ultra-high pressure vessels can be developed. In practical operations, it is necessary to develop specific procedures and parameter control methods based on different container types, materials, and processing requirements. .
