- 摘要:
- 梳理分析了国内输油、输气站工艺管道试压标准，提出借鉴国外标准的先进理念来提高国内输油、输气站设计和运行水平的思路。国外输油、输气站工艺管道试压标准的先进性主要体现在以下几方面：管道运行压力较低，强度试验和严密性试验合并进行，或者仅进行严密性试验；工艺管道划分原则；试压过程空气含量检测方法和降压程序；工艺管道试压周期等。此外还介绍了国内外关于输油、输气站工艺管道试压的先进技术和施工实例，包括利用严密性数学模型确定合理稳压时间；利用高压气体爆炸能量计算方法确定气试压损伤半径等。最后提出借鉴国外标准，提高我国输油、输气站工艺管道试压标准的建议。
Conducted is evaluation on pressure test standards for domestic oil and gas stations, put forward is the concept of drawing lessons from foreign advanced standards so as to improve design and operation level of domestic oil and gas stations. The advancement of foreign standards for oil and gas station process pipeline pressure test mainly includes the following aspects: low pipeline operation pressure, strength test together with leak test or leak test only, classification principles of process piping, pressure test process, air content detection method and the decompression procedure, process piping pressure test cycle, etc. Introduced are some advanced technologies and construction examples in oil and gas station process piping pressure test at home and abroad, including application of leak test mathematical model in determining reasonable pressure stabilization time and usage of high pressure gas explosion energy calculation method to determine gas pressure damage radius, etc., and it is suggested that drawing lessons from foreign standards to improve domestic oil and gas station process piping pressure test standards.
