目前有關地下管線的檢測主要依據API 570 Piping Inspection code，此Code乃針對石油煉製業及化學製程工業而發展，實用上亦可適用於任何管路。但地下管路因為可能會受土壤之影響而引起嚴重之外表腐蝕，故其檢測方法是與其他製程管線之檢查有所不同。因為地下管路有無法接近之特性，故其檢查也以獨立的章節呈現在API -570中。本文所敘之檢測方法，皆為非破壞檢測並且以不影響原管線之正常操作為原則。其他相關但非強制性之參考法規有：NACE RP-0169,NACE RP-0274,NACE RP- 0275以及API RP-651之第九節。 |
| 英文摘要 |
The current underground piping inspection method is according to the ''API 570 Piping Inspection Code'' which is developed for petrochemical and chemical processes. As the outer surface of underground pipe line may suffer sever corrosion by soil, and for its unaccessable characteristics, the inspection method of underground piping is quite different from other processing pipings, so that it was issued as an independent section in the API-570 Code. This review paper focus the non-destructive inspection methods from the API-570 and other non-mandatory referent practices such as NACE RP-0169, NACE RP-0274, NACE RP-0275 and API-651. |
