Preface
This is the fourth edition of CSA Z662, Oil and Gas Pipeline Systems. It supersedes the previous editions published in 1999, 1996, and 1994.
The following are the most significant changes, relative to the previous edition:
a) In Clause 1, a reference to ASTM E 29 has been added to provide a rounding method to be used for observed and calculated values in the determination of conformance with the specified requirements.
b) In Clause 3, definitions have been added for class location end boundary, direct deposition welding, fabricated assembly, indication, steel compression reinforcement repair sleeve, and undeveloped class location assessment area; and the definitions for class location assessment area, company, high-vapour-pressure (HVP) pipeline system, low-vapour-pressure (LVP) pipeline system, maximum operating pressure (MOP), pressure, and trenchless installation have been modified.
c) In Clause 4, requirements have been added concerning the selection of coatings and the effect of pipeline operating temperatures on the environment; and the requirements for class location designations, class location end boundaries, components, valve spacing, and limitations on the use of continuous welded pipe have been modified.
d) In Clause 5, the requirements for the qualification of materials, the use of cast iron, and cement-mortar linings have been modified.
e) In Clause 7, the requirements for the qualification of welding procedure specifications, nondestructive and visual inspection of production welds, the use of line-up clamps, stress relieving of welds, the reference reflector for ultrasonic inspection, and coupling loss in ultrasonic inspection have been modified.
f) In Clause 8, requirements have been added concerning the pressure testing of instrument piping and control piping; and the requirements for test-head assemblies and the determination of maximum operating pressure have been revised.
g) In Clause 9, requirements have been added concerning protective coatings and their application.
h) In Clause 10, requirements have been added concerning emergency response plans, leak detection for gas pipeline systems, the inspection of pipe used for underground storage, steel compression reinforcement repair sleeves, and direct deposition welding; and the requirements for signs, grinding repairs, the repair of underground tanks, the inspection frequency for pressure-relieving systems, the assessment of corrosion imperfections, and the assessment of dents have been modified.
i) In Clause 12, requirements have been added concerning polyethylene piping on bridges and test-head assemblies; and the requirements for design temperature for polyethylene pipe and tubing, cast iron pipe, the qualification of welders, and the squeezing of polyethylene piping have been modified.
j) In Clause 13, requirements have been added concerning fibre-reinforced composite pipelines and thermoplastic-lined pipelines; and the requirements for polyethylene pipelines have been modified.
k) In Clause 15, the requirements for the qualification of joining procedure specifications and the visual inspection, nondestructive inspection, and pressure testing of test joints for the qualification of joining procedure specifications and personnel have been modified.
l) Annex H has been added to provide a dictionary of common terminology for the recording of pipeline attribute and incident information in electronic database form.
m) In Annex K, the requirements for plastic failure analysis have been modified.
n) Annex L has been added to provide a guide for testing methods that are suitable for the evaluation of coating properties.
The requirements of this Standard are considered to be adequate under conditions normally encountered in the oil and natural gas industry. Specific requirements for abnormal or unusual conditions are not prescribed, nor are all details related to engineering and construction prescribed. It is intended that all work performed within the scope of this Standard meet the standards of safety and integrity expressed or implied herein, and that the requirements of this Standard be applied with due regard to the protection of the environment, which includes land, water, plant life, and animal life. Detailed requirements concerning the protection of the environment are not prescribed.
It is expected that changes will be made from time to time, based upon new experience and technology. Where necessary, amendments and supplements will be made by the Technical Committee and published in accordance with CSA practices.
This Standard was prepared by the Technical Committee on Oil and Gas Industry Pipeline Systems, under the jurisdiction of the Strategic Steering Committee on Oil and Gas Industry Systems and Materials, and has been formally approved by the Technical Committee. It will be submitted to the Standards Council of Canada for approval as a National Standard of Canada.
Scope
1.1
This Standard covers the design, construction, operation, and maintenance 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) carbon dioxide used in oilfield enhanced recovery schemes; or
e) gas.
Note: Designers are cautioned that the requirements in this Standard may not be appropriate for gases other than natural gas, manufactured gas, or synthetic natural gas.
1.2
The scope of this Standard, as shown in Figures 1.1 and 1.2, 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) for carbon dioxide pipeline systems, piping and equipment in onshore pipelines, pressure-regulating stations, and measuring stations;
d) for gas industry fluids, piping and equipment in offshore pipelines, onshore pipelines, compressor stations, measuring stations, and pressure-regulating stations;
e) gas compressor stations; and
f) gas storage lines and pipe-type and bottle-type gas storage vessels.
1.3
This Standard does not apply to
a) piping with metal temperatures below .70 °C;
b) piping (except oilfield steam distribution piping) with metal temperatures above 230 °C;
c) gas piping beyond the outlet of the customer's meter set assembly (covered by CSA B149.1);
d) 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;
e) oil refineries, terminals other than pipeline terminals, and marketing bulk plants;
f) abandoned piping;
g) in-plant piping for drinking, make-up, or boiler feed water;
h) casing, tubing, or pipe in oil or gas wells, wellheads, separators, production tanks, and other production facilities;
i) vent piping for waste gases of any kind operating at or near atmospheric pressure;
j) heat exchangers;
k) liquefied natural gas systems (covered by CSA Z276);
l) liquid fuel distribution systems;
m) loading/unloading facilities for tankers or barges;
n) refuelling facilities; and
o) hydrocarbon storage in underground formations and associated equipment (covered by CSA Z341).
1.4
This Standard is intended to establish essential requirements and minimum standards for the design, construction, and operation of oil and gas industry pipeline systems. This Standard is not a design handbook, and the exercise of competent engineering judgment is a necessary requirement to be employed concurrently with its use.
1.5
The requirements of this Standard are applicable to the operation, maintenance, and upgrading of existing installations; however, it is not intended that such requirements be applied retroactively to existing installations insofar as design, construction, and established operating pressures are concerned.
1.6
Unless otherwise stated, to determine conformance with the specified requirements, it is intended that observed or calculated values be rounded to the nearest unit in the last right-hand place of figures used in expressing the limiting value, in accordance with the rounding method of ASTM E 29.
1.7
Where any requirements of this Standard are at variance with the requirements of other publications incorporated by reference into this Standard, it is intended that the requirements of this Standard govern.
1.8
It is not the intent of this Standard to prevent the development of new equipment or practices, or to prescribe how such innovations should be handled.
1.9
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “shall be permissible”, “is permissible”, or “is permitted” is used to express that which is permitted; and “may” or “might” is used to express a possibility. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the tables and figures and may be written as requirements. Legends to equations and figures are considered requirements.
