12、ine began in the 1860s, the primary means of establishing pipeline integrity has been through the use of pressure testing. These tests have been most often performed upon completion of the construction of the pipeline. The completed pipeline segment has been pressurized to a level equal to or exceed

13、ing the anticipated maximum operating pressure (MOP). Government regulations have recently specified the test pressures, test media, and test durations that must be achieved for pipelines to be permitted to operate within their jurisdictions. However, until very recently, there have been no such req

14、uirements for pipelines to be periodically tested for integrity. Some pipeline operators have traditionally performed periodic integrity assessments in a variety of forms with varying degrees of success. In the mid 1960s, pipeline operators began to use a form of instrumented inspection technology t

15、hat has evolved into what is known today as in-line inspection (ILI). ILI is but one tool used in pipeline integrity assessment. The technology has now become so reliable that it holds a prominent place in many operators integrity programs because when properly applied, ILI provides many economies a

16、nd efficiencies in integrity assessment at a relatively small risk. This standard practice outlines a process of related activities that a pipeline operator can use to plan, organize, and execute an ILI project. Guidelines pertaining to ILI data management and data analysis are included. A key compa

17、nion guide to this standard is NACE International Publication 35100.1This standard is intended for use by individuals and teams planning, implementing, and managing ILI projects and programs. These individuals include engineers, operations and maintenance personnel, technicians, specialists, constru

18、ction personnel, and inspectors. Users of this standard must be familiar with all applicable pipeline safety regulations for the jurisdiction in which the pipeline operates. This includes all regulations requiring specific pipeline integrity assessment practices and programs. This NACE standard was

19、originally prepared by Task Group (TG) 212, “In-Line Nondestructive Inspection of Pipelines,” in 2002 and was revised by TG 212 in 2010. This standard is issued by NACE International under the auspices of Specific Technology Group (STG) 35, “Pipelines, Tanks, and Well Casings.” In NACE standards, th

20、e terms shall, must, should, and may are used in accordance with the definitions of these terms in the NACE Publications Style Manual. The terms shall and must are used to state a requirement, and are considered mandatory. The term should is used to state something good and is recommended, but is no

21、t considered mandatory. The term may is used to state something considered optional. _ SP0102-2010 ii NACE International _ NACE International Standard Practice In-Line Inspection of Pipelines Contents 1. General . 1 2.

24、on dioxide, water including brine, liquefied petroleum gases (LPG), and other services that are not detrimental to the function and stability of ILI tools. 1.2 This standard is primarily applicable to free-swimming ILI tools, but is not applicable for tethered or remotely controlled inspection devic

25、es. 1.3 This standard provides recommendations to the pipeline operator based on successful, industry-proven practices in ILI. 1.4 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

26、 such as hydrocarbon distribution and gathering systems, water injection systems, station piping, and isolated crossings of railroads, highways, or waterways. 1.5 ANSI(1)/ASNT(2)ILI-PQ2establishes minimum requirements for the qualification and certification of ILI personnel whose jobs require specif

27、ic knowledge of the technical principles of ILI technologies, operations, regulatory requirements, and industry standards as applicable to pipeline systems. 1.6 API(3)11633provides requirements for qualification of ILI systems used in onshore and offshore gas and hazardous liquid pipelines. This inc

28、ludes, but is not limited to, tethered or free-flowing systems for detecting metal loss, cracks, mechanical damage, pipeline geometries, and pipeline location or mapping. This standard is an umbrella document covering all aspects of ILI systems, including procedures, personnel, equipment, and associ

29、ated software. It is performance-based, but it does not define how to meet qualification requirements. _ Section 2: Definitions Aboveground Marker (AGM): A portable or permanently installed device placed on the surface above a pipeline that both detects and records the passage of an in-line inspecti
