1.1 本实施例描述了管道和导管（直径2英寸至96英寸（5厘米至244厘米））的重建程序，方法是将树脂浸渍的柔性织物管拉入现有导管中，并通过使用静水头或气压倒置校准软管进行二次充气（见 图1 ).通过循环热水、通过将受控蒸汽引入管中或通过光引发反应来固化树脂。固化时，成品原位固化管将是连续的和紧密的配合。这种重建过程适用于各种重力和压力应用，例如卫生下水道、雨水下水道、建筑管道、工艺管道、电气导管和通风系统。1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 注1: 没有涵盖该实践主要主题的ISO标准。 1.3 本标准的正文参考了提供解释什麽样什麽样的资料什麽样的注释和脚注什麽样的资料？这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为标准的要求。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 本实践供设计者和指定者、监管机构、所有者和检查组织使用，他们通过使用树脂浸渍织物管通过现有导管拉到位并通过倒置进行二次充气来修复导管。校准软管。特定的工作条件可能需要修改。

1.1 This practice describes the procedures for the reconstruction of pipelines and conduits (2 in. to 96 in. (5 cm to 244 cm) diameter) by the pulled-in-place installation of a resin-impregnated, flexible fabric tube into an existing conduit and secondarily inflated through the inversion of a calibration hose by the use of a hydrostatic head or air pressure (see Fig. 1 ). The resin is cured by circulating hot water, by the introduction of controlled steam into the tube, or by photoinitiated reaction. When cured, the finished cured-in-place pipe will be continuous and tight fitting. This reconstruction process is suitable for use in a variety of gravity and pressure applications such as sanitary sewers, storm sewers, building piping, process piping, electrical conduits, and ventilation systems. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Note 1: There are no ISO standards covering the primary subject matter of this practice. 1.3 The text of this standard references notes and footnotes which provide explanatory material; these notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of conduits through the use of a resin-impregnated fabric tube pulled-in-place through an existing conduit and secondarily inflated through the inversion of a calibration hose. Modifications may be required for specific job conditions.
