Is there any API or other standard about inspection of cross country pipelines? Which inspection types are recommended and what is the recommended frequency?

Thanks,
JZ

Recommended for you

Inspection types and frequency vary considerably depending on the fluid you have in your pipeline and the risk level.

Many operating companies work on an initial frequency of 7 to 10 years and then adjust it when the results come back.

Tell us more and you'll get more back in response

Not a design code; it is the (US) law.

49 CFR § 192.493 - In-line inspection of pipelines.

§ 192.493 In-line inspection of pipelines.
When conducting in-line inspections of pipelines required by this part, an operator must comply with API STD 1163, ANSI/ASNT ILI-PQ, and NACE SP0102, (incorporated by reference, see § 192.7). Assessments may be conducted using tethered or remotely controlled tools, not explicitly discussed in NACE SP0102, provided they comply with those sections of NACE SP0102 that are applicable.

49 CFR § 195.591 - In-Line inspection of pipelines.

§ 195.591 In-Line inspection of pipelines.
When conducting in-line inspection of pipelines required by this part, each operator must comply with the requirements and recommendations of API Std 1163, Inline Inspection Systems Qualification Standard; ANSI/ASNT ILI-PQ, Inline Inspection Personnel Qualification and Certification; and NACE SP0102-2010, Inline Inspection of Pipelines (incorporated by reference, see § 195.3). An in-line inspection may also be conducted using tethered or remote control tools provided they generally comply with those sections of NACE SP0102-2010 that are applicable.

@LittleInch

We have cross country gas lines and water lines.
Currently there is no inspection regime being followed for these lines.

The purpose of the question is to get knowledge about minimum requirements mentioned in different codes and then align our inspection regime accordingly.
