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 on new experience and technology. Where necessary, amendments and supplements will be prepared by the Technical Committee and published in accordance with CSA Group practices. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 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. Notes: 1) Vapour phase carbon dioxide pipeline systems fall under Item e). 2) Designers are cautioned that the requirements in this Standard might not be appropriate for gases other than natural gas, manufactured gas, vapour phase carbon dioxide, and 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) 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. 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; 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; and n) hydrocarbon storage in underground formations and associated equipment (covered by CSA Z341 Series). 1.4 This Standard is intended to establish essential requirements and minimum standards for the design, construction, operation, pipeline system management, and abandonment of oil and gas industry pipeline systems. This Standard is not an application manual for these activities. It is intended to be used by persons competent to make technical judgments in the areas to which this Standard is being applied including engineering, safety, and environmental protection. Note: Where newly developed materials or processes are used, or unusual conditions are encountered, requirements in addition to those specified in this Standard might be needed. 1.5 The requirements of this Standard are applicable to the operation, maintenance, and upgrading of existing installations. It is not intended that such requirements be applied retroactively to existing installations insofar as design, materials, construction, and established operating pressures are concerned, except as required by Clause 10.7.1 for changes in class location and Clause 10.8.1 for crossings of existing pipelines. 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 E29. 1.7 Where any requirements of this Standard are at variance with the requirements of other publications referenced in 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 are to 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; and "may" is used to express an option or that which is permissible within the limits of the Standard. 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 table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

ASME B1.20.1-2013 (R2018)

Pipe Threads, General Purpose, Inch

ASME’s widely-referenced B1.20.1 Standard on Pipe Threads, General Purpose, Inch covers dimensions and gaging of the world’s most common pipe threads: NPT, NPSC, NPTR, NPSM, and NPSL.  From critical applications demanding robustness and precision to common plumbing and hardware, these threads are used everywhere in the United States and abroad.   This long awaited revision incorporates both subtle and substantive changes, including:  Moving of the gaging point of reference of external threads in certain circumstances; A new acceptability section for instances of gaging disputes; A change to parameters, facilitating the calibration of working gages; Guidance for plated or coated pipe threads; Better explanatory language for the lay-user. This is the foundational Standard for NPT, NPSC, NPSM, and NPSL pipe threads. All companies that manufacture, sell, or use these threads should have this revision in their technical library.

ASCE MOP 145-2021

Design of Close-Fit Liners for the Rehabilitation of Gravity Pipes

Prepared by the Pipeline Infrastructure Committee of the Utility Engineering and Surveying Institute of ASCE

Design of Close-Fit Liners for the Rehabilitation of Gravity Pipes, MOP 145, provides a comprehensive source of information on the design of flexible, close-fit linings for the renewal or rehabilitation of pipes designed for gravity flow such as sanitary sewers, culverts, and storm sewers.

Introductory topics discussed include pipe-soil structure interaction, condition assessment and inspection methods, and lining options, but the main focus is on the thickness design of close-fit flexible liners. This design is based on a closed-form solution, which takes into account both the current shape of the host structure as well as the potential imperfections of the liner (annular gap) and of the host structure (cracks or fractures).

The design solutions presented can be used for circular and noncircular geometries such as pipe-arch shapes, egg shapes, elliptical shaped pipes (both horizontal and vertical), box shaped pipes (both rectangular and square), and other, undefined site-specific shapes.

This Manual of Practice covers the thickness design of flexible liners to be installed in a gravity-flow sewer or culvert pipe; the host pipe can be rigid or flexible and be circular or noncircular; the installation method is trenchless and yields a close-fit lining, cured-in-place lining, or fold-and-form lining.

MOP 145 will provide guidance to consulting engineers tasked with designing flexible close-fit liners for rehabilitation of existing gravity pipe applications.
