Oil and gas pipelines systems

1.1

This Standard covers the design, construction, operation, maintenance, deactivation, and abandonment of oil and gas industry pipeline systems that convey

a) liquid hydrocarbons, including crude oil, multiphase fluids, condensate, liquid petroleum products, natural gas liquids, and liquefied petroleum gas;

b) oilfield water;

c) oilfield steam;

d) liquid or dense phase carbon dioxide; or

e) gas.

Note:

1) Vapour phase carbon dioxide and hydrogen pipeline systems fall under Item e).

 

1.2

The scope of this Standard includes

a) for oil industry fluids, piping and equipment in offshore pipelines, onshore 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) for gas industry fluids, piping and equipment in offshore pipelines, onshore pipelines, compressor stations, measuring stations, and pressure-regulating stations;

f) gas compressor stations; and

g) gas storage lines and pipe-type and bottle-type gas storage vessels.

Note: Gas industry fluids from renewable natural gas (RNG) and other production facilities are included in e).  

 

1.3

This Standard does not apply to

a) piping with metal temperatures below –70 °C;

b) gas piping beyond the outlet of the customer’s meter set assembly (covered by CSA B149.1);

c) piping in natural gas liquids extraction plants, gas processing plants (except main gas stream piping in dehydration and all other processing plants installed as part of gas pipeline systems), gas manufacturing plants, industrial plants, and mines;

d) oil refineries, terminals other than pipeline terminals, and marketing bulk plants;

e) abandoned piping;

f) in-plant piping for drinking, make-up, or boiler feed water;

g) casing, tubing, or pipe in oil or gas wells, wellheads, separators, production tanks, and other production facilities;

h) vent piping for waste gases of any kind operating at or near atmospheric pressure;

i) heat exchangers;

j) liquefied natural gas systems (covered by CSA Z276);

k) liquid fuel distribution systems;

l) loading/unloading facilities for tankers or barges;

m) refuelling facilities;

n) hydrocarbon storage in underground formations and associated equipment (covered by CSA Z341 Series);

o) RNG, biogas and synthetic gas production facilities; and

p) hydrogen gas production facilities.
