| 绝缘垫块 Insulating pad 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。 When pipeline cathodic protection is constructed, there will always be metal pipe sleeves when crossing roads, railways and rivers. In order to prevent the pipeline from contacting with the pipe sleeve, the fixed insulation block on the official road is generally adopted, and the insulation pad is generally made of plastic. The support strength should be determined according to the wall thickness of the pipeline and the transport medium. The general support spacing is controlled at 1.5-2.0 M. 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。 The end of the pipeline is installed with support and insulation joints. The two groups of supports are installed at the end of the pipe and installed according to the row. The distance between the middle parts is evenly placed according to the safe distance of the design requirements. Like some special casing, such as concrete casing, in order to prevent the insulation from being damaged too much, a steel trustee support is added to the front end, and the steel outer tube support is not less than the insulation support. |
