Standardization in the field of pipeline transportation of fluids specific for oil and gas industries including lower carbon energy activities.

Objects of standardization comprise the following elements of the on-land and offshore pipelines:

• pipeline system as a whole including gathering lines and distribution piping,
• line pipe (excluding: ferrous metal pipes and metallic fittings related to ISO/TC 5, aluminium alloy pipes related to ISO/TC67/WG5),
• valves and their equipment (including actuators and mounting kits),
• bends, flanges, and fittings (including corrosion resistant ones),
• pipeline connectors,
• pipeline repair techniques and materials,
• external protective coatings (including polyolefin, polypropylene, polyethylene, polyurethane, and epoxy),
• external insulating coatings (including wet thermal insulation),
• external weight coatings (including concrete coating),
• internal anticorrosion coatings (excluding protective paint systems for steel structures related to ISO/TC 35/SC 14).

Aspects of standardization comprise the concepts relating to design, construction, operation, inspection, and maintenance of the pipeline systems, including:

• integrity management,
• fluid transfer modes,
• life extension,
• risk management including those risks initiated by geological hazards,
• in-field coating repairs,
• corrosion protection including cathodic protection and prevention of corrosion influenced by stray currents,
• requirements for the transportation of fluids containing carbon dioxide,
• requirements for the transportation of fluids containing hydrogen,
• requirements for ammonia transportation,
• test procedures of different elements of pipeline systems,
• non-destructive testing including in-line inspection,
• repair methods,
• terminology.
