29、vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a
30、technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matter
31、s of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulat
32、ed to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible
33、 for identifying any or all such patent rights. ISO 14692-3 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and systems. ISO 14692 consists of the following pa
34、rts, under the general title Petroleum and natural gas industries Glass-reinforced plastics (GRP) piping: Part 1: Vocabulary, symbols, applications and materials Part 2: Qualification and manufacture Part 3: System design Part 4: Fabrication, installation and operation SANS 14692-3:2009This s tandar

36、t the specified performance requirements. These piping systems are designed for use in oil and natural gas industry processing and utility service applications. The main users of the document will be the principal, design contractors, suppliers contracted to do the design, certifying authorities and
37、 government agencies. An explanation of the pressure terminology used in this part of ISO 14692 is given in ISO 14692-1.

44、SO 14692-3:2002(E) 2 ISO 2002 All rights reserved5 Layout requirements 5.1 General GRP products are proprietary, and the choice of component sizes, fittings and material types may be limited depending on the supplier. Potential vendors should be identified early in design to determine possible limit
45、ations of component availability. The level of engineering support that can be provided by the supplier should also be a key consideration during vendor selection. Where possible, piping systems should maximize the use of prefabricated spoolpieces to minimize the amount of site work. Overall spool d
46、imensions should be sized taking the following into consideration: limitations of site transport and handling equipment; installation and erection limitations; limitations caused by the necessity to allow a fitting tolerance for installation (“cut to fit” requirements). The designer shall evaluate s
47、ystem layout requirements in relation to the properties of proprietary pipe systems available from manufacturers, including but not limited to: a) axial thermal expansion requirements; b) ultraviolet radiation and weathering resistance requirements; c) component dimensions; d) jointing system requir
48、ements; e) support requirements; f) provision for isolation for maintenance purposes; g) connections between modules and decks; h) flexing during lifting of modules; i) ease of possible future repair and tie-ins; j) vulnerability to risk of damage during installation and service; k) fire performance
49、; l) control of electrostatic charge. The hydrotest provides the most reliable means of assessing component quality and system integrity. Whenever possible, the system should be designed to enable pressure testing to be performed on limited parts of the system as soon as installation of those parts is complete. This is to avoid a final pressure test late in the construction work of a large GRP pipe system, when probl
