Overhead pipelines have large heat loss, and the insulation layer is exposed to the atmosphere. It is easily damaged by rain, snow and sand, so the insulation layer needs to be repaired and replaced frequently.
Several practices are often used for overhead pipe insulation:
1. Pipe rust removal → brush antirust paint → smear asbestos powder and other materials mixed with cement insulation material → bandage iron mesh sheet → ash asbestos cement protective shell → brush anti-corrosion paint.
2. Pipe rust removal → brush antirust paint → banding pearlite tile → galvanized iron wire → asphalt linoleum moisture barrier layer → outer galvanized iron sheath protection layer → brush topcoat.
3, pipe derusting → brush anti-rust paint → package ultra-fine glass wool shell (or rock wool, polyurethane foam tile) → aluminum foil (or asphalt linoleum) moisture barrier → galvanized iron protective layer → topcoat.
4, pipe derusting → brush anti-rust paint → polyurethane directly sprayed in the pipeline foam → aluminum foil → galvanized iron protective layer → topcoat.
The insulation of the overhead pipeline requires that the insulation layer be dense and void-free, the insulation layer is even and smooth, and the lap width of the moisture-proof layer should meet the requirements of the specification. The joint should be overlapped as far as possible, and the protective layer should not be wrapped with glass cloth.
According to Jiuzheng Building Materials Network, when the galvanized iron protective layer is processed, the curvature should meet the pipe diameter requirements, and the longitudinal joints should be placed in the lower part of the pipe. It is forbidden to lap upward or diagonally to prevent rain and snow from entering the protective layer.
The galvanized iron protective layer shall be processed at the elbow, and the elbow package consisting of not less than 3 tiles shall be processed. In order to reduce the heat loss at the valve and the like, the valve body part shall be insulated.
