| 在管道阴极保护施工时，经常会遇到穿越马路、铁路以及河流的时候，一般会有金属管套。为了防止管道与管套的接触，一般采取官道上固定绝缘垫块，绝缘垫块一般采用塑料制成的。支撑力度和要根据管道的壁厚还有输送的介质从而断定的，一般的支撑间距控制在1.5-2.0米。 In the construction of pipeline cathodic protection, we often encounter metal pipe sleeves when crossing roads, railways and rivers. In order to prevent the contact between pipeline and pipe sleeve, the insulating pad is usually fixed on the official road, and the insulating pad is usually made of plastic. Supporting force and media should be determined according to the wall thickness of the pipeline, and the general support spacing should be controlled at 1.5-2.0 meters. 管道的端头安装支撑绝缘接头采用端头两组支撑并按排安装，中间段距离按设计要求的安全距离均匀安放。像一些特殊的套管，如混凝土套管，为防止绝缘拉运是受损过大，一般采取前端增加一个钢制托管支架，钢制外圆托管支架不小于绝缘支架。 Insulation joints are installed at the end of the pipeline by two groups of supports at the end and arranged in rows. The distance between the middle section is evenly arranged according to the safe distance required by the design. Like some special bushings, such as concrete bushings, in order to prevent excessive damage to insulation pulling, a steel trustee bracket is usually added to the front end, and the steel trustee bracket is no less than the insulation bracket. |
