  1. 管道防腐
  1. Pipeline anti-corrosion
  (1)基本治疗
  (1) Basic treatment
  黑套保温管的底处理质量直接影响防腐层的粘结质量和防腐效果。目前常用的底层处理方法有喷雾解吸、化学解吸、化学解吸和化学解吸。野外常用的方法主要有喷发法和除锈法。
  The bottom treatment quality of black sleeve insulation pipe directly affects the bonding quality and anticorrosive effect of anticorrosive coating. At present, the commonly used bottom treatment methods include spray desorption, chemical desorption, chemical desorption and chemical desorption. The common methods in the field are eruption and derusting.
  (2)防腐结构
  (2) Anticorrosive structure
  施工防腐涂料时,在雨、雪、风、沙等环境及相对湿度较大的情况下,没有有效的施工方法。
  During the construction of anticorrosive coating, there is no effective construction method under the conditions of rain, snow, wind, sand and relative humidity.
  防腐涂层的类型应按规定分层。涂布厚度应均匀,无流动、起皱、针孔和空心滚筒缺陷。干燥后可采取保养方法。胶带型涂料应严格使用。控制施工温度,不要过热。
  The type of anti-corrosion coating shall be layered as specified. The coating thickness shall be uniform without flow, wrinkling, pinhole and hollow drum defects. After drying, maintenance methods can be taken. Tape type coating shall be strictly used. Control the construction temperature and do not overheat.

  2. 管道保温
  2. Pipeline insulation
  当黑套保温管保温层厚度大于100mm时,应分层。非水平管道的保温结构由下至上,防潮层与维护层重叠部分向下压紧,重叠宽度不小于30mm。
  When the thickness of the insulation layer of the black sleeve insulation pipe is greater than 100mm, it shall be layered. The insulation structure of non horizontal pipeline is from bottom to top, and the overlapping part of damp proof layer and maintenance layer is pressed down, and the overlapping width is not less than 30mm.
  安装前对带报警线的预制保温管进行开关状态及警戒线电阻值检测。报警线的尺寸应符合货物的要求,然后对管焊接。报警线应位于管道上方。一旦报警线受潮,应通过预热或烘烤使其干燥。
  Before installation, check the switch status and guard line resistance value of the prefabricated insulation pipe with alarm line. The size of the alarm line shall meet the requirements of the goods, and then the pipe shall be welded. The alarm line shall be located above the pipe. Once the alarm line is damp, it shall be dried by preheating or baking.
  在进行绝缘工作之前,应在保证套管密封合格后,对直埋绝缘管的接口进行检查。
  Before the insulation work, the interface of the directly buried insulating pipe shall be inspected after the casing seal is qualified.
