This review article critically analyzes the selection and compatibility assessment framework of metallic alloys in pure oxygen (>99.5%) atmospheres using promoted combustion and particle impact ignition tests in combination with the Pressure-Velocity (PV) curves. The historical test data for four important metallic alloys frequently used in the oil and gas industry, namely nickel alloys C276 and 600, stainless steel 304 and 316, are mined and analyzed to: (i) capture trends and correlation of data obtained by these two tests with the PV curves, (ii) identify gaps in the data for critical process variables such as temperature, pressure and gas velocity, (iii) identify limitations of the two tests, (iv) understand the relevance of shape factors and geometry of test samples and flowing vs. non-flowing conditions on test results and (v) evaluate whether exemption pressures and PV curves can be extended or adjusted for important metals to accommodate more demanding conditions. In industry practices, PV curves are utilized to impose velocity limitations in oxygen systems to help mitigate particle impact ignition when the operating pressures are greater than alloys exemption pressures. Our analysis shows, current version of PV curves - based primarily on historical data and industry experience are conservative, limited to specific thicknesses and available only up to 200 °C for both exempt and non-exemptalloys. For the oil and gas industry where conditions up to 300°C and 80 bar are desired, there is a need to conduct new testing to develop guidelines for thinner cross-sections and more demanding operating conditions including higher temperatures and pressures.This will open avenues for new innovations and applications of gaseous oxygen and help industries operate their plants with higher efficiencies.

这篇评论文章批判性地分析了纯氧 (>99.5%) 环境中金属合金的选择和兼容性评估框架，使用促进燃烧和粒子撞击点火测试并结合压力-速度 (PV) 曲线。对石油和天然气行业常用的四种重要金属合金，即镍合金 C276 和 600、不锈钢 304 和 316 的历史测试数据进行挖掘和分析，以： (i) 捕捉趋势和这两者获得的数据的相关性使用 PV 曲线进行测试，(ii) 确定关键过程变量数据中的差距，例如温度、压力和气体速度，(iii) 确定两个测试的局限性，(iv) 了解形状因素和测试几何形状的相关性样品和流动对比 测试结果中的非流动条件和 (v) 评估是否可以针对重要金属扩展或调整豁免压力和 PV 曲线以适应更苛刻的条件。在工业实践中，当操作压力大于合金豁免压力时，PV 曲线用于对氧气系统施加速度限制，以帮助减轻粒子撞击点火。我们的分析表明，当前版本的 PV 曲线 - 主要基于历史数据和行业经验是保守的，仅限于特定厚度，并且对于豁免和非豁免合金仅适用于 200 °C。对于需要高达 300°C 和 80 bar 的条件的石油和天然气行业，
