            摘要:
            采用內襯層為PVDF、增強層為玻璃鋼帶的柔性復合管,利用承壓設備,基于線性回歸采用剩余強度法對油氣集輸用柔性復合管的服役壽命進行研究。利用掃描電鏡對微觀形貌分析,對柔性復合管的失效機理進行研究。結果表明,隨著服役時間的增加,柔性復合管的剩余強度值呈下降趨勢,并且該對數值與服役時間對數值呈線性關系。該類型管材無外界因素影響,在輸送介質溫度不高于90 ℃,壓力不高于16 MPa條件下,可安全服役超過20年。
            Abstract:
            Using the residual pressure strength method based on the linear regression to study the service life of the flexible composite pipe for oil and gas gathering and transportation, the flexible composite pipe use PVDF as the lining layer and the fiberglass reinforced resin band as the reinforced layer. The failure mechanism of the reinforced thermoplastic pipe is studied by scanning electron microscopy. The results show that the residual pressure strength of the reinforced thermoplastic pipe tends to decrease with the service time increasing, and the logarithmic value is linear with the service time. Under the condition of no external factors, this type pipe can be safely served for more than 20 years if the medium temperature is not higher than 90 ℃and the pressure is not higher than 16 MPa.
