【英文标准名称】: Standard Practice for Rehabilitation of Existing Pipelines and Conduits by the Inversion and Curing of a Resin-Impregnated Tube 【原文标准名称】: 通过树脂浸渍管的倒置和硫化修复现有管线和管道的标准实施规程 【标准号】: ASTM F1216-2007b 【标准状态】: 现行 【国别】: 【发布日期】: 2007 【实施或试行日期】: 【发布单位】: 美国材料与试验协会(ASTM)【起草单位】: F17.67【标准类型】: (Practice)【标准水平】: ()【中文主题词】: 电工导管;电气工程;检修;树脂【英文主题词】: 【摘要】: 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 tube inverted through the existing conduit. As for any practice, modifications may be required for specific job conditions. 1.1 This practice describes the procedures for the reconstruction of pipelines and conduits (4 to 108-in. diameter) by the installation of a resin-impregnated, flexible tube which is inverted into the existing conduit by use of a hydrostatic head or air pressure. The resin is cured by circulating hot water or introducing controlled steam within the tube. When cured, the finished pipe will be continuous and tight-fitting. This reconstruction process can be used in a variety of gravity and pressure applications such as sanitary sewers, storm sewers, process piping, electrical conduits, and ventilation systems.1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see 7.4.2. 【中国标准分类号】: G33;P94【国际标准分类号】: 23_040_20; 23_040_20【页数】: 7P.;A4【正文语种】:
