CSA Z260:25

1 Scope 1.1 Service fluids This Standard applies to liquid and gaseous energy systems that convey a) liquid hydrocarbons, including crude oil, multiphase fluids, condensate, and liquid petroleum products; b) natural gas liquids and liquefied petroleum gas; c) oilfield water; d) oilfield steam; e) liquid or dense phase carbon dioxide; or f) gas, including but not limited to natural gas, fuel gas, hydrogen and hydrogen blends, compressed air, carbon dioxide, and nitrogen. See Figures 1and 2. Notes: 1) Non-hydrocarbon products used as process fluids and transported by operating companies by pipeline or within pipeline facilities are considered within the scope of this Standard, provided that those products are used in facilities connected to the pipeline system. 2) Fluids used within equipment supporting the pipeline system operation, including consumables such as lubricating or hydraulic fluids, are considered within the scope of this Standard, provided that the equipment is connected to the pipeline system at the time of the pipeline system safety event (PSSE). 1.2 Stations and equipment This Standard applies to a) piping and equipment in onshore liquids pipelines, tank farms, pump stations, pressure-regulating stations, and measuring stations; b) oil pump stations, pipeline tank farms, and pipeline terminals; c) pipe-type storage vessels; d) carbon dioxide pipelines; e) piping and equipment in onshore gas pipelines, compressor stations, measuring stations, and pressure-regulating stations; f) gas storage lines, and pipe-type and bottle-type gas storage vessels; g) loading and unloading facilities for tankers or barge, truck, and rail when connected to the process; and h) gas distribution systems.
