1.1 本规程涵盖了管道和导管的重建程序（4 在里面至72英寸。(100 mm至1830mm）直径），然后用压缩空气压力充气（参见 图1 )以使其紧靠主体结构的壁表面牢固地膨胀。然后将管中的光引发树脂系统暴露于紫外线（UV）下固化。固化后，完工的就地固化管道将是一个连续且紧密配合的管道。这种类型的重建过程可用于各种重力流应用，如卫生下水道、雨水下水道、工艺管道、电气管道和通风系统。 图1 紫外线固化就地管道安装方法（空气/蒸汽） 1.2 以英寸-磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。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，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本规程适用于通过使用树脂浸渍玻璃纤维管修复导管的设计者和规范制定者、监管机构、所有者和检验机构，通过现有管道或导管将其拉入适当位置，然后充气，然后通过设计的紫外线照射进行固化- 光对于任何标准实践，可能需要针对特定工作条件进行修改。

1.1 This practice covers the procedures for the reconstruction of pipelines and conduits (4 in. to 72 in. (100 mm to 1830 mm) diameter) by the pulled-in place installation of a resin-impregnated, glass fiber tube into an existing pipe or conduit followed by its inflation with compressed air pressure (see Fig. 1 ) to expand it firmly against the wall surface of the host structure. The photo-initiated resin system in the tube is then cured by exposure to ultraviolet (UV) light. When cured, the finished cured-in-place pipe will be a continuous and tight fitting pipe within a pipe. This type of reconstruction process can be used in a variety of gravity flow applications such as sanitary sewers, storm sewers, process piping, electrical conduits, and ventilation systems. FIG. 1 UV Cured-In-Place Pipe Installation Method (Air/Steam) 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. 1.3 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. 1.4 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 glass fiber tube, pulled in place through an existing pipe or conduit, subsequently inflated and then cured by a designed exposure to UV-light. As for any standard practice, modifications may be required for specific job conditions.
