The method provides a basis of pressure joint matching design and technological test.
油气田集输管道采用压接技术,其压接接头不存在焊接接头的隐患,连接效率高,施工成本低。
The water injection and gas discharge device is added,the flexible pressure testing sub is used and the high and low pressure water conversion valve body is improved.
通过增加管体注水排气装置、采用柔性试压接头、改进注水端高低压水转换阀体等措施,解决了油管试压机存在的损伤油管螺纹、试压接头消耗快、试压过程密封性能差、生产效率低、安全性差等问题。
