scope:

This standard is applicable to carbon steel pipeline systems used to transport natural gas, hazardous liquids including anhydrous ammonia, carbon dioxide, water including brine, liquefied petroleum gases (LPGs), and other services that are not detrimental to the function and stability of ILI tools.

This standard is primarily applicable to ¿free-swimming¿ ILI tools but not tethered or remotely controlled inspection devices.

This standard provides recommendations to the pipe Iine ope rato r based on successfuI, industry-proven practices in ILI.

This standard is specific to the inspection of line pipe installed along a right-of-way, but the general process and approach may be applied to other pipeline facilities such as hydrocarbon distribution and gathering systems, water injection systems, station piping, and isolated crossings of railroads, highways, or waterways.
