18、SO 2010 All rights reservedForeword 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

19、 in a subject for which a 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 Comm

20、ission (IEC) on all matters 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 technic

21、al committees are circulated 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 sha

23、010(E) ISO 2010 All rights reserved vIntroduction This International Standard classifies the techniques used for the renovation of existing pipelines and gives information on the design of plastics piping systems used for such renovation. Over the past 25 years, the rehabilitation of pipeline system

24、s has become increasingly important. Pipeline systems are continuously required to satisfy physical, chemical, biochemical and biological demands. These demands depend on planning, material, construction, type and period of use. When pipeline systems become operational, proper system management has

25、to be put in place. In addition to inspection and cleaning, rehabilitation of the pipeline can be required. Rehabilitation is carried out when there is need for restoration or upgrading of the pipeline system in terms of its performance. Rehabilitation can consist of repair, renovation or replacemen

26、t. To coincide with the publication of ISO product standards for various families of renovation techniques in three different application areas, the need to upgrade ISO/TR 11295 to a full International Standard was recognized, and, at the same time, focus on renovation.

27、 11295:2010INTERNATIONAL STANDARD ISO 11295:2010(E) ISO 2010 All rights reserved 1Classification and information on design of plastics piping systems used for renovation 1 Scope This International Standard defines and describes families of techniques for the renovation of non-pressure and pressure p

28、ipelines through the use of plastics pipes, fittings and ancillary components. For each technique family, it identifies areas of application from the range covered by existing renovation product standards, which include underground drainage and sewerage, and underground water and gas supply networks

29、. This International Standard provides information on the principles of, but not the detailed methodologies for, the design of plastics piping systems applied as linings to existing pipelines, covering: existing pipeline and site conditions; lining system functions; structural performance; hydraulic

30、 performance; other factors affecting lining system selection. It does not cover the calculation methods used to determine, for each viable technique, the required amount of lining material needed to secure the desired performance of the renovated pipeline. 2 Normative references The following refer

43、In addition, certain general characteristics of each renovation technique family are described. NOTE 1 The pipe materials listed in 5.2 to 5.7 reflect the state-of-the-art in the technique families on the date of publication of this International Standard. Not all technique families/material-combina

44、tions are covered by a renovation product standard. The Bibliography gives relevant available standards. NOTE 2 The application areas covered by existing renovation product standards include underground drainage and sewerage, and underground water and gas supply networks. This International Standard

45、 is not applicable to other possible areas of application of the technique families described. 5.2 Lining with continuous pipes Lining with continuous pipes is defined as lining with pipes made continuous prior to insertion; the cross-section of the lining pipe remains unchanged (see Figure 2).
