This document specifies requirements and gives recommendations on the management of geohazard risks of pipeline during the design, construction and operational periods.

This document shall apply to all operators and pipeline systems (existing and proposed/under construction), unless the operator can clearly demonstrate why the document should not apply.

This document applies to onshore gathering and transmission pipelines used in the petroleum and natural gas industries[1].

This document is applicable to all reasonable and credible natural hazards and hazards induced by human activity that manifest similarly to natural hazards, collectively referred to as “Geological Hazards” or “Geohazards”. Geohazards covered by this document include, but are not limited to (not given in order of significance):

—    mass wasting processes, including landslides, rockfalls, debris flows, avalanches, and similar processes whether naturally occurring or anthropogenic;

—    land subsidence and/or sinkhole formation, whether naturally occurring such as from dissolution of salt or carbonate rock formations (karst formation) or human caused, such as from underground mining or withdrawal of subsurface fluids such as groundwater and oil and gas;

—    seismic hazards, such as ground shaking, fault rupture, liquefaction, flow failures and lateral spreading or associated secondary effects, such as seismically triggered landslides;

—    volcanic hazards, such as lahars, pyroclastic flows, lava flows, dam break, and volcanically induced seismicity (excluding ashfall), where such hazards can be reasonably predicted;

—    hydrologic processes, such as flooding, vertical scour of river bottoms, channel migration and bank erosion, channel avulsion, rapid lake drainage;

—    permafrost/periglacial processes and geothermal effects, such as frost heave or thaw settlement;

—    surface and backfill erosion;

—    expansion or collapsing process caused by expansive and collapsible soils, such as glaciomarine clays, collapsible loess, etc.

This document does not cover atmospheric effects such as:

—    high winds induced from hurricanes and tornadoes and similar storms, except where such events are reasonably predictable and will induce geohazards such as landslides, erosion, etc.,

—    lightning,

—    forest or brush fires,

—    ashfall from volcanic eruptions,

—    tsunamis induced by seismic hazards.

Furthermore, this document does not cover so-called cascading events, where one remote event leads to a chain of events that eventually induces a geohazard near the pipeline. Only geohazards that directly affect the pipeline or RoW are covered.


[1] Piping and pipelines within well-defined plants and facilities, such as pump or compressor stations, processing facilities or refineries are not covered by this document. It is assumed that the facility site as a whole will be subject to a separate geohazard assessment to evaluate applicable natural and man-made hazards. Nevertheless, this document may provide useful guidance for assessing the geohazard threat to facilities, including the pipelines within the facility.

This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material.

For pipes covered by this International Standard, the sizes, masses and wall thicknesses, as well as, grades and applicable end-finishes are listed in Tables C.1 and C.2 and Tables E.1 and E.2.

By agreement between the purchaser and manufacturer, this International Standard can also be applied to other plain-end pipe sizes and wall thicknesses.

API Spec 5L pipe may be ordered as casing in accordance with API RP 5C6.

This International Standard is applicable to the following connections in accordance with API Spec 5B:

short round thread casing (SC);

long round thread casing (LC);

buttress thread casing (BC);

non-upset tubing (NU);

external upset tubing (EU);

integral tubing (IJ).

For such connections, this International Standard specifies the technical delivery conditions for couplings and thread protection. Supplementary requirements that can optionally be agreed for enhanced leak resistance connections (LC) are given in A.9 SR22.

This International Standard can also be applied to tubulars with connections not covered by ISO/API standards.

1.2       The products to which this International Standard is applicable include the following grades of pipe: H40, J55, K55, N80, L80, C90, R95, T95, P110, C110 and Q125.

1.3     Casing sizes larger than Label 1: 4-1/2 but smaller than Label 1: 10-3/4 can be specified by the purchaser to be used in tubing service, see Tables C.1, C.23, C.27 and C.28 or Tables E.1, E.23, E.27 and E.28.

1.4     Supplementary requirements that can optionally be agreed between purchaser and manufacturer for non-destructive examination, fully machined coupling blanks, upset casing, electric-welded casing, tubing and pup joints, impact testing, seal ring couplings,enhanced leak resistance, tensile testing, sulfide stress cracking testing, yield strength, hardenability and hardness testing are given in Annex A.

1.5     This International Standard is not applicable to threading requirements.

NOTE          Dimensional requirements on threads and thread gauges, stipulations on gauging practice, gauge specifications, as well as, instruments and methods for inspection of threads are given in API Spec 5B.


Dual referencing of normative references

In the interests of world-wide application of this International Standard, ISO/TC 67 has decided, after detailed technical analysis, that certain normative documents listed in Clause 3 and prepared by ISO/TC 67 or other ISO Technical Committee are interchangeable in the context of the relevant requirement with the relevant document prepared by the American Petroleum Institute (API), the American Society for Testing and Materials (ASTM) or the American National Standards Institute (ANSI). These latter documents are cited in the running text following the ISO reference and preceded by “or”, for example “ISO XXXX or API YYYY”. Application of an alternative normative document cited in this manner will lead to technical results different from the use of the preceding ISO reference. However, both results are acceptable and these documents are thus considered interchangeable in practice.
