Oil Pipeline Transportation Systems
This fourth edition of CSA Standard Z183, Oil Pipeline Transportation Systems, supersedes previous editions published in 1967, 1973, and 1977.
This Standard is part of the Pipeline Systems and Materials segment of CSA’s Transportation program and is identified as such by the Transportation symbol on the front cover.
This edition differs mainly from the third edition as follows:
(a) The scope of the Standard has been extended to the oil well-head and now covers the transportation of multiphase fluids, including reinforced epoxy resin pipe requirements. Also, requirements for offshore pipelines have been added to appropriate clauses throughout the Standard. Future editions of his Standard may require expansion and modification of these subjects.
Throughout the Standard he term oil pipeline covers all services contained in Clause 1.1.1;
(b) Definitions have been revised to complement the text and to follow industry practice;
(c) SI (metric) units have been adopted throughout the Standard;
(d) The design formula is now expressed in terms of nominal pipe wall thickness;
(é) Notch toughness criteria have been added for HVP pipelines;
(f) Material requirements for sour multiphase service have been added;
(g) Welding clauses have been extensively revised to comply with current procedures and materials;
(h) Inspection requirements are now specifically directed towards new or replacement installations unless cross-referenced to the Operation, Maintenance and Repair Clause;
(i) The hydrostatic test period for steel pipelines has been reduced to a 4 h strength test and a 4 h leak test;
(j) Requalification of pipelines to confirm line integrity, or to qualify a pipeline for a higher maximum operating pressure, has been added;
(k) Field tolerances related to mechanical damage and other defects are no longer more stringent than pipe-mill tolerances and tolerances in dents are now related to pipe diameter ranges, with clarified repair procedures;
(l) Clause 1O is now expanded and titled Corrosion Control, including both internal and external corrosion under one heading.
This Standard contains basic reference data and formulae relating to design, supplemented by specific requirements, where necessary, to obtain a uniform interpretation of the design requirement. It refers to unsafe pipeline practices that are prohibited and sets out warnings where caution must be exercised. In addition, this Standard contains a bibliography (Appendix A) listing applicable reference standards organizations that may be of interest to users of this Standard.
This Standard is intended to establish essential requirements and minimum standards for the design, installation, and operation of oil pipeline systems. It is not a design handbook and the need for exercising competent engineering judgement is a necessary requirement to be employed concurrently with its use.
The requirements of this Standard are adequate under conditions normally encountered in the oil industry. Requirements for abnormal or unusual conditions are not specifically provided for, nor are all details of engineering and construction prescribed. It is intended that all work performed within the scope of this Standard shall meet or exceed the safety standards expressed or implied herein.
As with all new Standards, it is to be expected that changes may have to be made from time to time based on new experience or technology, or both. When necessary to do so, amendments will be made by the Committees and published in accordance with CSA practices.
This Standard was prepared by the CSA Technical Committee on Oil Pipeline Code under the jurisdiction of the Standards Steering Committee on Pipeline Systems and Materials and was formally approved by these Committees.
This Standard covers the design, material selection, fabrication, installation, inspection, testing, operation, maintenance, and repair of pipeline systems, that carry crude oil, multiphase fluids, condensate, liquid petroleum products. natural gas liquids, and liquefied petroleum gas at or between facilities shown in Figure 1.1.
The scope of this Standard is shown in Figure 1.1 and includes:
(a) All pressure pipe, valves, fittings and auxiliary components used in pipeline systems, tank farms, pump stations, pressure reducing stations, and metering stations; and
(b) Selection of materials and installation of tank farms and pump stations in accordance with other referenced codes and standards. with specific references to Clause 3.7.
This Standard does not cover the following:
(a) Auxiliary piping systems such as those used for air. water, steam, gas, fuel, and lubricating oil;
(b) Casing, tubing, or pipe in oil wells, wellheads, separators, production tanks, or other production facilities;
(c) Terminals (other than pipeline), refineries, marketing bulk plants, or gas processing plants;
(d) Gas pipeline systems;
(e) Liquefied natural gas lines;
(f) Fuel distribution systems; and
(g) Tanker and barge loading/unloading facilities.
It is not intended that the application of this Standard shall operate to prevent the development of new equipment or practices, nor to prescribe specifically how such innovations should be handled.
Where any requirements of this Standard are at variance with the requirements of other standards or codes incorporated by reference into this Standard, the requirements of this Standard shall govern.
The requirements of this Standard shall not be applied retroactively to existing installations or to installations under construction at the time of its approval but shall apply to the extension, repair, maintenance, and up-rating of such installations.
The term shall as used in this Standard indicates a mandatory requirement. The term should indicates a recommended practice.
